North and central Georgia brace for isolated storms and high heat risk as hazardous outlook issued for Monday
The National Weather Service has issued a Hazardous Weather Outlook covering north and central Georgia for Monday, August 18, 2025. Forecasters say isolated thunderstorms are possible this afternoon across portions of the region, with no severe weather expected. However, storms could bring frequent lightning, locally heavy rain, and gusty winds. Heat index values are forecast to reach the upper 90s to around 100 degrees in many areas today.
From Tuesday through Sunday, the pattern shifts to more widespread thunderstorm activity. Scattered thunderstorms are expected each afternoon and evening across north and central Georgia, though coverage will vary by location. In meteorological terms, isolated thunderstorms describe a few storm cells with large gaps between them, while scattered thunderstorms indicate a broader area with multiple storms affecting roughly 30% to 50% of the forecast zone.
A long list of counties is included in the outlook, spanning north and central Georgia, with many communities potentially impacted by thunderstorms at various times through the week. The statement notes that isolated storms today will be capable of lightning and gusty winds, along with heat indices that make outdoor exposure potentially hazardous.
What this means for residents
– Today: Expect isolated storms this afternoon in parts of north Georgia. If you are outdoors, monitor weather updates, choose shaded or indoor locations during storm activity, and stay hydrated as heat index values rise.
– Tonight: If storms occur, plan for brief heavy rain and possible thunderstorm-related hazards.
