# Southeast US heat and storms Aug-Sept 2026 > Live situation record from CLSTR: https://clstr.news/situations/georgia-severe-thunderstorms-and-flooding > Updated: 2026-09-12T11:17:51.000Z. Sources: 44. Developments: 24. Late July and August 2026 saw continued volatility in the Southeast. On July 28, a mesoscale convective system moved across North Georgia, producing straight-line winds up to 75 mph in Catawba County, NC, and causing widespread tree damage across several Georgia counties. The National Weather Service confirmed an EF-0 tornado in Pickens County with maximum winds of 80-85 mph, causing sporadic damage in Jasper and leaving over 5,000 residents without power. In early August, the National Weather Service issued a hazardous weather outlook for north and central Georgia, warning of scattered thunderstorms and flash flooding through August 7. The Weather Prediction Center placed coastal South Carolina under a Marginal Risk for excessive rainfall, with localized flooding possible in Charleston and surrounding low-lying areas. Similar threats of rain and wind extended into Florida and the broader Southeast. By mid-August, extreme heat returned to the region. A heat advisory in effect through August 17 warned of heat index values reaching as high as 109 degrees, with high humidity providing little overnight relief. Concurrently, the Storm Prediction Center placed North Georgia under a marginal risk for severe storms, forecasting threats of damaging winds, torrential rain, and frequent lightning fueled by a hot, moist airmass. By August 17, a dangerous heat wave expanded across much of the Southern and Southeastern United States, with heat indices expected to reach as high as 115 degrees in some areas. In West Tennessee, an extreme heat warning was issued through Sunday, forecasting heat indices at or above 107 degrees in Memphis, where urban areas may see little nighttime relief. Simultaneously, unsettled weather including heavy rain, flash flooding, and severe thunderstorms impacted the Midwest, Ohio Valley, and Mid-Atlantic, particularly in the central Appalachians and parts of eastern Tennessee and western North Carolina. ## Timeline ### 2026-09-12: Georgia faces thunderstorms, dense fog, and high heat North and central Georgia face hazardous weather, including increasing thunderstorms, dense fog, and heat index values reaching the low 100s through early next week. 3 sources. https://clstr.news/cluster/georgia-faces-thunderstorms-dense-fog-and-high-heat ### 2026-09-04: North Carolina faces severe storms and extreme heat Severe storms and extreme heat have caused widespread power outages, fallen trees, and property damage across North Carolina, with heat indices reaching 109°F in some areas. 3 sources. https://clstr.news/cluster/north-carolina-faces-severe-storms-and-extreme-heat ### 2026-09-04: North Georgia faces extreme heat and severe storm risks North Georgia faces extreme heat with index values reaching triple digits and a risk of severe storms before a cooler front arrives for Labor Day. 5 sources. https://clstr.news/cluster/north-georgia-faces-extreme-heat-and-severe-storm-risks ### 2026-08-26: Georgia weather returns to heat, humidity, and storm risks Georgia faces a return of high humidity, heat, and frequent thunderstorms, with warnings issued for potential flash flooding and damaging winds in north and central regions. 5 sources. https://clstr.news/cluster/georgia-weather-returns-to-heat-humidity-and-storm-risks ### 2026-08-17: Extreme heat and severe storms impact Southern and Eastern United States Extreme heat and high heat indices are impacting the Southern and Southeastern US, while severe storms and flash flooding threaten the Midwest, Appalachia, and parts of Tennessee and North Carolina. 4 sources. https://clstr.news/cluster/extreme-heat-and-severe-storms-impact-southern-and-eastern-united-states ### 2026-08-16: Georgia faces extreme heat and severe storm threats Georgia faces a heat advisory with heat indices potentially reaching 109 degrees, alongside a risk of severe storms capable of producing damaging winds and heavy rain. 6 sources. https://clstr.news/cluster/georgia-faces-extreme-heat-and-severe-storm-threats ### 2026-08-04: Heavy Rain and Flash Flood Risk Threatens Georgia and Southeast US Heavy rain, thunderstorms and gusty winds bring flash‑flood risk to Georgia and the Southeast, with coastal South Carolina under marginal excessive‑rainfall warnings. 2 sources. https://clstr.news/cluster/heavy-rain-and-flash-flood-risk-threatens-georgia-and-southeast-us ### 2026-07-29: North Georgia Severe Storms Spawn EF-0 Tornado in Pickens County Severe storms in North Georgia produced damaging winds, downed trees and a confirmed EF‑0 tornado in Pickens County, leaving over 5,000 without power. 2 sources. https://clstr.news/cluster/north-georgia-severe-storms-spawn-ef-0-tornado-in-pickens-county ### 2026-07-26: Georgia heat advisory issued as triple-digit heat index expected A heat advisory is expected for north and central Georgia as triple‑digit heat indices and isolated thunderstorms are forecast through early next week. 4 sources. https://clstr.news/cluster/georgia-heat-advisory-issued-as-triple-digit-heat-index-expected ### 2026-07-19: Severe Thunderstorms and Heat Wave Expected Across North and Central Georgia North and central Georgia face severe thunderstorms with gusty winds, lightning, flash‑flooding risk and a heat wave pushing heat‑index values into the low 100°F range through the week. 5 sources. https://clstr.news/cluster/severe-thunderstorms-and-heat-wave-expected-across-north-and-central-georgia ### 2026-07-13: North Carolina Faces Flash Flood Threat Ahead of Extreme Heat Wave Flash flood warning in central North Carolina with up to 5 inches of rain; travel disruptions expected.
