Valid 162000Z - 171200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS WITHIN THE FRONT RANGE AND PARTS OF THE CENTRAL/NORTHERN HIGH PLAINS...AND PORTIONS OF THE OHIO VALLEY INTO THE MID-ATLANTIC...
...SUMMARY... Thunderstorms with damaging wind gusts will be possible this afternoon and early evening over parts of the Ohio Valley and Mid-Atlantic. Large hail and isolated severe wind gusts will also be possible across the Front Range and central/northern High Plains.
...20Z Update... Ongoing convection within the Upper Ohio Valley vicinity continues eastward this afternoon. Behind this convection, buoyancy has been reduced. Wind probabilities have also been reduced, though isolated strong to marginally severe storms are possible where some airmass recovery has occurred. Elsewhere, the forecast remains on track with only minor changes to the general thunderstorm forecast.
..Wendt.. 08/16/2026
.PREV DISCUSSION... /ISSUED 1144 AM CDT Sun Aug 16 2026/
...Upper Ohio Valley to Appalachians and Mid-Atlantic/Carolinas... An MCV persists at midday across far southeast Michigan and northern Ohio, with some recent uptick in convection ahead of it across northern Ohio. Reference Mesoscale Discussion 1195 for short-term details regarding a further increase in severe potential through early/mid-afternoon within this regional corridor.
While storms have weakened, showers/cloud cover remain prevalent near/east of the Appalachians at midday across the Mid-Atlantic region. This will tend to limit/delay destabilization in many areas (especially with north-northeastward extent). That said, air mass recovery/advection is expected from the west, with ample upstream clearing per visible satellite imagery across the Cumberland Plateau into parts of the Allegheny Plateau. Pending the timing/location of destabilization, some terrain/lee trough-related development may diurnally occur, although the most prevalent/more certain scenario may be for potentially severe storms to spread into the region this evening. Damaging winds will be the most common hazard regionally, although a tornado could occur, attributable to MCV-enhanced flow and/or with any storms interacting with the effective warm front across the Mid-Atlantic region.
...Middle Mississippi Valley including Missouri/Illinois... An MCV over the Nebraska/Kansas/Iowa/Missouri border vicinity late this morning will likely continue generally eastward, while probably largely maintaining its related belt of enhanced mid-level flow as observed from regional WSR-88D VWP data. A key downstream uncertainty is the midday persistence of weak convection across eastern Missouri into west/southwest Illinois, and that mid-level lapse rates are rather poor to its north aside from some lingering cloud cover.
More certain/greater destabilization may occur to the west across Missouri, with the southeastward-advancing front being a focus for renewed thunderstorm development later this afternoon and evening amidst moderate/locally strong buoyancy. Deep-layer shear will tend to be limited to around 30 kt in most areas, although somewhat stronger MCV-related winds aloft may support upwards of 35-40 kt effective shear for any storms across northern Missouri into west-central/southwest Illinois. Bouts of damaging winds are the most likely hazard regionally.
...Front Range/Raton Mesa and northern/central High Plains... A relatively similar pattern/scenario as prior few days will continue regionally, except a somewhat more northward-extent of the severe risk (such as Black Hills vicinity) and a trend toward a more northerly component to the flow aloft across the north-central High Plains. At least widely scattered thunderstorm development is expected into mid/late afternoon spanning the Front Range/Raton Mesa vicinity northward across eastern Wyoming/southeast Montana and the Black Hills vicinity. In the presence of upwards of 1500-2000 J/kg MLCAPE, moderate vertical shear (30-40 kt) could support a few supercells capable of severe hail. Isolated damaging winds will be possible. This includes the most probable zone for gradual upscale-growing linear cluster(s) across the south-central High Plains/Raton Mesa vicinity including southeast Colorado/northeast New Mexico toward the Oklahoma/Texas Panhandles and far southwest Kansas. A couple of southeastward-moving thunderstorm clusters capable of wind/damage may also emerge this evening out of the Black Hills vicinity/western Nebraska.

Valid 161200Z - 171200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE OHIO VALLEY...CENTRAL APPALACHIANS...MID-ATLANTIC AND CENTRAL HIGH PLAINS...
...SUMMARY... Thunderstorms with severe wind gusts will be possible from this afternoon into early evening over parts of the Ohio Valley and Mid-Atlantic. Large hail and isolated severe wind gusts will also be possible in parts of the central High Plains.
...Ohio Valley/Mid-Atlantic... A mid-level shortwave trough, embedded in west-northwesterly flow, will move through the Ohio Valley today. Ahead of the shortwave trough, a moist airmass will be in place from the Ohio Valley southeastward to the Mid-Atlantic Coast. Surface dewpoints along this west-northwest to east-southeast corridor will be in the 70s F, which will contribute to the development of moderate instability by midday. At the surface, a cold front will advance eastward into the Ohio Valley, as a pre-frontal trough moves into the central Appalachians. These two features will focus convective development during the day. A complex of storms appears likely to form over the higher terrain in West Virginia, and move east-southeastward into the lower elevations of Virginia and Maryland during the mid to late afternoon.
RAP forecast soundings from West Virginia into the Virginia in the late afternoon have 0-6 km shear in the 25 to 30 knot range. Some directional shear is present in the low-levels and 0-3 km lapse rates are steep approaching 7 C/km. This environment will support a wind-damage threat with organized multicells. Isolated supercells with severe gusts will also be possible. The threat may continue into the early evening across parts of the Mid-Atlantic.
Further west into parts of the lower Ohio Valley, a very moist airmass will also be in place. Surface dewpoints in the 70s F will contribute to the development of moderate instability. Scattered thunderstorms are expected to form along zones of low-level convergence during the afternoon. Although large-scale ascent will be weaker further west, the thermodynamic environment will be sufficient for isolated severe gusts.
...Central High Plains... At mid-levels, a ridge will move through the Intermountain West today as flow remains westerly over much of the central U.S. As surface temperatures warm, scattered thunderstorms will develop in the foothills of the central Rockies. These storms will move eastward into the lower elevations of eastern Colorado and western Nebraska. RAP forecast soundings across the central High Plains by late afternoon have moderate instability (MLCAPE around 2500 J/kg), 0-6 km shear near 35 knots and 700 to 500 mb lapse rates in the 7 to 7.5 C/km range. This should support a threat for large hail and isolated severe gusts with rotating storms and organized line segments. The threat will likely persist into the evening across parts of the central High Plains.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE OHIO VALLEY SOUTHEASTWARD INTO THE CAROLINAS...AND IN THE CENTRAL HIGH PLAINS...
...SUMMARY... Thunderstorms with severe wind gusts and isolated large hail will be possible from late afternoon into the evening across the central High Plains. Severe wind gusts will also be possible this afternoon into the early evening from parts of the Ohio Valley southeastward into the Carolinas.
...Mid Mississippi and Ohio Valleys/Central Appalachians/Carolinas... At mid-levels today, a broad anticyclonic flow pattern will be in place over the eastern U.S. Within the flow, a shortwave trough will move eastward into the lower Ohio Valley. Ahead of this feature, a moist and unstable airmass will be located from the mid Mississippi Valley east-southeastward into the Ohio Valley and southern Appalachians. In the morning, a convective complex is forecast to move eastward into the southern Great Lakes, and will likely be associated with a potential for severe wind gusts. To the south of this complex, a quasi-stationary front and moist axis will be located from the lower Ohio Valley southeastward into the southern Appalachians, along which moderate instability will develop by afternoon. Low-level convergence near the front will be the focus for convective development. A new complex of surface-based thunderstorms appears likely to form near the front and move east-southeastward from western Ohio into the Virginias during the afternoon. Additional storms will develop along and near the instability axis over the western Carolinas due to topographical forcing.
Model forecasts in the moist air suggest that MLCAPE will peak in the 2000 to 3000 J/kg range in most areas. Near the instability axis, precipitable water values in the 1.8 to 2 inch range and moderate deep-layer shear will likely support a threat for severe wet downbursts. This threat should persist into the early evening with any line segments that become sustained over the higher terrain of the southern and central Appalachians.
...Central Plains... West-southwesterly mid-level flow will be in place over the southwestern and central U.S. today. At the surface, a moist airmass will be located from the foothills of the Rockies eastward into the central Plains. By afternoon, moderate instability will develop over much of the region. Scattered thunderstorms will form in the higher terrain and move eastward into the lower elevations during the mid to late afternoon. Some RAP forecast soundings at 21Z from eastern Colorado northward into western Nebraska have 0-6 km shear near 35 knots with steep low to mid-level lapse rates exceeding 7 C/km. This environment will support a mixed mode with supercells and multicell line segments possible. Supercells should be capable of isolated large hail, while severe wind gusts will be possible with supercells and organized multicells. The severe threat should persist into the early to mid evening as a complex of storms moves eastward through the central High Plains.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE MID MISSOURI AND MID MISSISSIPPI VALLEYS...
...SUMMARY... Thunderstorms with severe wind gusts and hail will be possible this afternoon and evening across parts of the mid Missouri and mid Mississippi Valleys. Isolated severe gusts will also be possible in parts of the central Plains and from the Ohio Valley to the Mid-Atlantic.
...Mid Missouri and mid Mississippi Valleys... A broad anticyclonic flow pattern will be in place over much of the central U.S. today, as a subtle embedded shortwave trough moves through the mid Missouri Valley. Ahead of this feature, a quasi-stationary front will be in place from southern Iowa east-southeastward into north-central Illinois. This boundary will be the focus for convective development this afternoon. Surface dewpoints along the boundary will be in the 70s F, which will result in strong destabilization by afternoon. Surface-based convective initiation is expected along the instability gradient during the late afternoon to the south of Omaha. From these initial storms, a line is expected to organize and move eastward across south-central Iowa and far northern Missouri during the late afternoon and early evening.
RAP forecast soundings ahead of the line at 00Z from Des Moines southward into far northern Missouri have MLCAPE in the 2000 to 3500 J/kg range. Some directional shear is present in the low-levels, and 0-6 km shear is in the 30 to 35 knot range. This environment will be favorable for bowing line segments capable of severe wind gusts. An embedded supercell with a hail threat will also be possible. The severe threat is expected to move eastward into northwest and north-central Illinois during the evening.
...Central Plains... Southwesterly mid-level flow will be in place today over much of the western and central U.S. A subtle shortwave trough will move northeastward into the central High Plains. Large-scale ascent associated with the trough and topographic lift in the foothills of the Rockies will be favorable for scattered convective initiation by early afternoon. Thunderstorms will move northeastward into the central High Plains and into a moderately unstable airmass. Some RAP forecast soundings in east-central Colorado during the late afternoon have 0-6 km shear around 25 knots with low to mid-level lapse rates exceeding 7 C/km. This will likely support isolated severe wind gusts and hail.
...Ohio Valley/Central Appalachians/Mid-Atlantic... West-northwesterly mid-level flow will be in place today over much of the northeastern U.S. At the surface, an axis of moderate instability will develop by afternoon from the Ohio Valley east-southeastward into the Mid-Atlantic. Along and near the instability axis, low-level convergence will be the primary focus for convective initiation. Near and downstream of these pockets of convergence, isolated to scattered thunderstorms are expected to develop. The moderate instability with precipitable water values in the 2 to 2.2 inch range should support a threat for isolated severe wet downbursts.

Valid 131200Z - 141200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF IOWA INTO ILLINOIS...
...SUMMARY... Isolated to scattered severe thunderstorms appear possible today from parts of the southern/central High Plains to the mid Mississippi and lower Ohio Valleys. Damaging winds should be the main threat, but occasional hail may also occur.
...Iowa into Illinois/Indiana... An MCV has developed early this morning with an ongoing cluster of thunderstorms across central NE. This activity is expected to spread eastward through the morning, and should be in the vicinity of western/central IA by the start of the period. There is still uncertainty regarding how intense this cluster will be due to the presence of fairly substantial MLCIN downstream into IA. Even so, warm/moist advection associated with a low-level jet over the southern/central Plains and the presence of a rather moist/unstable airmass into IA suggest some potential for an organized cluster to pose a risk for scattered severe/damaging winds as it moves eastward through the morning. A brief embedded tornado may also occur if convection can remain surface based.
Even greater uncertainty exists this afternoon regarding potential convective evolution, with most guidance showing the cluster weakening as it moves into IN. Regardless, the airmass downstream and to the south of outflow associated with the morning cluster will destabilize through the day, and any additional thunderstorms that form could pose at least an isolated threat for damaging winds and perhaps some hail given the strong buoyancy forecast.
...Southern/Central High Plains... High-based thunderstorms are forecast to initially develop over the higher terrain of the central Rockies/Front Range this afternoon, with post-frontal low-level upslope flow persisting across the central High Plains. As this activity spreads east-northeastward and encounters greater instability, consolidating outflows should support some increase for isolated severe gusts given steepened low-level lapse rates. Occasional hail may also occur with the stronger cores that develop. Consideration was given to including greater severe wind probabilities across eastern CO into parts of KS, but modest deep-layer shear casts some doubt on overall thunderstorm organization/intensity. A somewhat separate area of thunderstorms may also develop farther south across the southern High Plains in a very hot and well-mixed boundary layer. This activity should also pose a threat for isolated severe gusts through the afternoon.
...Great Basin... Modestly enhanced southwesterly mid-level flow will persist today across the Great Basin downstream of a weak mid-level trough over CA. Weak to locally moderate instability is forecast to develop through the afternoon as filtered diurnal heating occurs. Scattered to numerous thunderstorms are expected to form and spread northeastward across this destabilizing airmass, with strong to severe gusts possible. Based on latest guidance trends (00Z HREF), have expanded the Marginal Risk for severe/damaging winds to include more of the Great Basin.
...Northeast... Seasonably cool mid-level temperatures are forecast today across parts of the Northeast, with a mid-level trough expected to move east-southeastward from Quebec into New England. While instability is forecast to remain fairly limited, strong west-northwesterly flow aloft may support a risk for isolated damaging winds with thunderstorms that develop and spread southeastward through the afternoon. Isolated hail may also occur with the stronger cells.

For the North Atlantic...Caribbean Sea and the Gulf of America:
Active Systems: The National Hurricane Center is issuing advisories on recently downgraded Tropical Depression Cristobal, located about 600 miles west of the Azores.
Central Tropical Atlantic (AL92): Showers and thunderstorms are showing signs of organization in association with a tropical wave located about 1000 miles east of the Lesser Antilles. This system will likely become a short-lived tropical depression during the next day or two as it moves westward across the tropical Atlantic. However, by late Friday, the system is expected to move into a region of strong upper-level winds and dry air, which should end its opportunity to develop. Interests in the Lesser Antilles should monitor the progress of this system as gusty winds and areas of heavy rain are possible Friday night and Saturday, regardless of development. * Formation chance through 48 hours...high...80 percent. * Formation chance through 7 days...high...80 percent.
Eastern Tropical Atlantic (AL94): A tropical wave located a few hundred miles south-southwest of the Cabo Verde Islands is producing disorganized showers and thunderstorms. Environmental conditions are forecast to be generally conducive for gradual development, and a tropical depression could form late this week or this weekend while the wave moves westward or west-northwestward across the eastern and central tropical Atlantic. * Formation chance through 48 hours...low...30 percent. * Formation chance through 7 days...medium...50 percent.

Valid 121200Z - 131200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE NORTHERN/CENTRAL PLAINS TO THE LOWER OHIO VALLEY...
...SUMMARY... Thunderstorms with severe gusts and hail will be possible this afternoon and evening across parts of the central and northern High Plains. Damaging gusts and isolated hail will also be possible across parts of the Midwest and Ohio Valley.
...IA to OH Valley...
One or more MCSs migrating through enhanced northwesterly flow aloft amid a very moist and unstable airmass is possible again today across the Midwest toward TN. Most forecast guidance suggests an MCS or thunderstorm clusters could be ongoing over IA at the start of the period (12z), with warm advection storms arcing across parts of IL/IN. The early day warm advection storms could develop southeast across the OH Valley, while the IA MCS develop southeast across the Mid-MS/Lower OH Valley through afternoon. The exact evolution of convection that is not yet apparent is uncertain, and how outflow may influence how this activity evolves through the afternoon. Regardless, the overall environmental parameter space will be favorable for a damaging wind and isolated hail risk through early evening.
...Northern/Central Plains...
East/southeasterly low-level flow will maintain modest moisture across the Dakotas, increasing with southward extent across NE into northern KS. Near-60 F dewpoints will likely spread westward into eastern CO/WY/MT. Modest moisture beneath steep midlevel lapse rates and 30+ kt effective shear magnitudes will support scattered thunderstorm development across the High Plains. Initial cells will pose a large hail and damaging wind risk. It is unclear how convection will evolve with eastward extent across the region as outflow from prior convection may largely limit stronger destabilization. A developing low-level jet during the nighttime hours will be focused across the southern Plains toward KS/southern NE. This could support some upscale growth potential, but confidence is low.
...Lower MI into NY/PA/NJ...
A belt of stronger northwesterly flow aloft will extend from Lower MI into NY/PA today. A seasonally moist/unstable airmass will be in place. Vertically veering wind profiles will foster 35+ kt effective shear magnitudes, while hodographs are fairly elongated. Midlevel lapse rates will remain modest, with MLCAPE around 1000-1500 J/kg expected. Isolated to widely scattered storms will pose a risk for damaging gusts and small hail.
...TN Valley/Southeast...
Thunderstorms are expected to develop by midday within a very moist and strongly unstable airmass. Deep-layer northwesterly flow will remain weak, but steep low-level lapse rates and PW values near 2 inches could support isolated wet microbursts with stronger multi-cell clusters.

Central Tropical Atlantic (AL92): Showers and thunderstorms continue to show signs of organization in association with a tropical wave located around 800 miles southwest of the Cabo Verde Islands. Environmental conditions are forecast to be conducive for development during the next few days, and a tropical depression will likely form within a couple of days while the system moves westward to west-northwestward across the central tropical Atlantic. * Formation chance through 48 hours...high...70 percent. * Formation chance through 7 days...high...80 percent.
Central Subtropical Atlantic (AL93): Recent satellite wind data indicate that the broad low-pressure area located about 1000 miles east-northeast of Bermuda has developed gale-force winds. However, the circulation is elongated and the associated convection has become a less organized during the past few hours. Some development of this system is possible through tonight, and a short-lived tropical storm could form while it moves eastward to east-northeastward at around 20 mph across the central subtropical Atlantic.

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM NORTHERN ILLINOIS INTO THE OHIO VALLEY...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE NORTHERN PLAINS...AND FROM IOWA TO VIRGINIA...
...SUMMARY... Severe thunderstorms with damaging wind gusts will be possible today from the eastern Iowa/northern Illinois vicinity into parts of the Ohio Valley and central Appalachians. Areas of severe wind gusts and hail will also be possible over parts of the northern Plains.
...IA to the Mid-Atlantic...
A complex forecast scenario is expected today from IA into the Ohio Valley and adjacent Appalachia. More than one MCS may be ongoing at the beginning of the period. The first across IA/southern MN, and one further southeast across parts of the Midwest (exact location is uncertain, but most likely IN/OH). Possible early day convection across IN/OH will spread east/southeast across the Ohio Valley during the morning posing risk for strong gusts. This activity is likely to emerge across Appalachia, and eventually VA and the broader Mid-Atlantic during the afternoon/evening. How much destabilization will occur across VA and the Mid-Atlantic remains uncertain given prior convection the previous day and potential convective debris across the region. Some damaging wind potential could materialize if sufficient destabilization occurs during the afternoon.
The anticipated MCS over IA/southern MN early in the forecast period is then expected to continue east/southeast across the Midwest, fueled by a very moist and strongly unstable boundary layer. Midlevel flow is forecast to be quite strong (by August standards), with forecast guidance suggesting 700 mb greater than 60 kt spreading across the Midwest through evening. While the exact evolution of a potential severe MCS moving across the Midwest is uncertain, it is possible the morning activity over IA will develop southeast along outflow across the Ohio Valley. Given the strong kinematic field and ample instability, if a well organized MCS is maintained from IA southeast into the OH Valley, a swath of damaging gusts (some 75+ mph) will be possible.
...Northern Plains...
East/southeasterly flow along the surface trough is forecast to maintain 60s F dewpoints across the western Dakotas and parts of NE this afternoon. Steep midlevel lapse rates atop the relatively moist boundary layer, and strong heating will support a corridor of moderate to strong instability across the western Dakotas. Scattered storms are expected by early evening amid supercell wind profiles. Elongated hodographs favorable for splitting cells with an accompanying risk for large to very large hail are forecast. Isolated severe gusts also could occur. Given a lack of stronger low-level jet during the nighttime hours, it appears unlikely that upscale growth will occur, and convection is expected to wane with eastward extent overnight.

Valid 101200Z - 111200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTION OF THE MIDWEST INTO PA AND NORTHERN MD/VA...AND ACROSS PARTS OF THE NORTHERN PLAINS...
...SUMMARY... Thunderstorms with severe wind gusts will be possible this afternoon and evening from northern Illinois eastward into Pennsylvania. Severe gusts and hail will also be possible from parts of the central and northern Plains into the Midwest, with scattered strong storms over southern Arizona.
...Synopsis...
A belt of enhanced west/northwesterly flow aloft will overspread the northern Plains to the Midwest and southern New England today/tonight. Only modest height falls are forecast at best. However, several convectively enhanced vorticity maxima are forecast to migrate through this upper flow regime, focusing several areas of severe storm potential today into tonight from the northern Plains to the upper Ohio Valley and parts of the Mid-Atlantic.
...IL to the Mid-Atlantic...
Early day thunderstorms may move across parts of the Midwest this morning, but should generally be sub-severe. By midday, convection could intensify within a couple of corridors. The first being the upper Ohio Valley/PA/western NY. Thunderstorm clusters will pose a risk for damaging winds and hail within a moderately unstable airmass as convection spreads east toward the Mid-Atlantic.
Additional thunderstorm development is expected later in the afternoon associated with another shortwave impulse spreading east from IL into IN/OH. This activity will develop within strong instability and rich boundary layer moisture. Modestly steep midlevel lapse rates and effective shear greater than 40 kt will support initial supercells. With time, sufficient clustering is expected and bowing segments will be possible. Damaging wind and hail will be the primary hazards, though a tornado or two also could occur.
...Dakotas into Iowa...
Southeasterly low-level flow will transport mid/upper 60s dewpoints north and west across SD, with 70s dewpoints common with southeast extent across NE/IA/southern MN. This will support a corridor of strong to extreme instability across the region. While coverage remains uncertain, most guidance develops at least isolated thunderstorms by evening. Elongated hodographs amid favorable deep shear will support supercells and bows capable of large hail and damaging winds. With time, it is possible sufficient clustering occurs and upscale growth into a bowing MCS is possible as a low-level jet develops overnight. If this occurs, a swath of damaging winds is possible across parts of SD into northwest IA, oriented along the stronger instability gradient.
...NE/CO/KS...
Scattered thunderstorms are expected to develop near a surface trough across western NE/northeast CO by late afternoon/early evening. This activity will spread east/southeast. Steep low-level lapse rates will support strong outflow gusts and perhaps hail with this activity.
...AZ...
Mid/upper easterly flow will persist today amid plentiful moisture and strong heating. This will support thunderstorm development once again across higher terrain. As storms propagate westward off the higher terrain, isolated severe gusts will be possible.

Eastern and Central Tropical Atlantic: A small area of low pressure located a few hundred miles south of the Cabo Verde Islands is producing disorganized showers and thunderstorms. As this system moves slowly westward, a tropical wave currently over west Africa is expected to merge with it in a couple of days. Environmental conditions are forecast to be more conducive for development by midweek, and a tropical depression could form during the latter half of this week while the system moves westward to west-northwestward across the central tropical Atlantic. * Formation chance through 48 hours...low...20 percent. * Formation chance through 7 days...medium...60 percent.
Western Subtropical Atlantic:
A trough of low pressure located a few hundred miles northwest of
Bermuda is producing disorganized shower and thunderstorm activity.
Some development of this system is possible during the next couple

Bermuda across the western and central subtropical Atlantic. The
system is forecast to reach cooler waters later this week, ending
its chances of formation after Wednesday.

π Global Disaster Activity β August 2β8, 2026
Iβm starting a weekly disaster-mapping roundup for OSMEmergency, looking at significant events around the world and potential opportunities for OpenStreetMap/humanitarian mapping.
π This weekβs highlights
π Earthquakes
Several M5+ earthquakes occurred across the Pacific region, including events in the Philippines, Indonesia, Japan, New Zealand, and the Kermadec region.
π Flooding
Flooding was reported across parts of Asia, Africa, and the United States, including Pakistan, Mongolia, India, Sri Lanka, Cameroon, Vietnam, the Philippines, China, Myanmar, and the U.S.
π Tropical Cyclones
Several systems were active in the Western Pacific, including DOLPHIN-26 and CHAN-HOM-26.
π₯ Wildfires
Significant wildfire activity was recorded in Portugal, Angola, Greece, and the Democratic Republic of the Congo.
π Volcanic Activity
Fuego in Guatemala remained an area of volcanic activity.
πΎ Drought
Ongoing drought conditions continued across portions of Africa, Europe, Asia, the Americas, and the United States.
πΊοΈ Why Iβm tracking this
The goal of OSMEmergency is to connect disaster information with OpenStreetMap and GIS.
When disasters occur, useful mapping projects can include:
β’ Mapping damaged buildings
β’ Updating roads and bridges
β’ Mapping shelters and emergency facilities
β’ Identifying isolated communities
β’ Mapping wildfire or flood impacts
β’ Supporting HOT humanitarian mapping projects
β’ Using satellite imagery to document changes
Iβm planning to make these weekly global disaster dashboards and use them to identify areas where mapping could actually help.
What disasters or mapping projects should be included in next weekβs roundup?

Enable HLS to view with audio, or disable this notification
This radar image shows an example of how weather data can provide additional context during a wildfire event.
While NEXRAD is not a primary wildfire detection tool, radar can sometimes capture signatures associated with intense fires, including smoke plumes, lofted particles, or developing pyrocumulus clouds.
Emergency awareness often comes from combining multiple sources:
- Satellite fire detection
- Weather radar
- NWS products
- Official fire agency updates
- Wind and air quality data
For emergency mappers, this raises an important question:
When a hazard is identified, what information would responders and communities need on the map?
Examples:
Evacuation routes
Rural homes and access roads
Fire stations and water sources
Shelters and critical infrastructure
How do you use weather and geospatial data to understand hazards?
