Isolated to scattered thunderstorms are expected this afternoon and evening across northern and central Georgia. Isolated damaging winds could occur, but widespread severe weather is unlikely.
Hot weather continues today, with heat index values expected to reach 97 and 102 degrees in the afternoon. Precautions should be taken to ensure adequate hydration and access to cooling.
Isolated thunderstorms will be possible again on Monday, Thursday and Friday this upcoming week.

Current Streamflow Situation from the USGS network of streamflow gauges through Georgia
Sunday's streamflow map appears similar to yesterday, an even mix of normal and below normal ratings on both sides of the divide. The highest flow values recorded are once again found in the northwest Coosa River watershed, above 90th percentile. Water released from Buford Dam has spiked the streamflow gauge on Chattahoochee River above Roswell to 95th percentile, the rest of the area free-flowing creeks and rivers show a mix of normal to much below normal values. The lowest flows Sunday include a 1st percentile recorded on Chattahoochee River at Columbus, and 2nd percentile near Columbia, AL. A new section of the Chattahoochee River watershed is rated below normal on the drought map Sunday in keeping with the extreme low flow levels midchannel. The below normal rated area extends from Muscogee to Clay County. Still hanging around the drought map Sunday, Tallapoosa and Flint watersheds rated below normal on the Gulf side of the divide. On the Atlantic side, Satilla, lower Ocmulgee and Savannah River watersheds have area rated below normal another day. For details on the areas impacted with drought ratings, click here.
WT USA Flood Tracker provisional data from the network of USGS streamflow monitors
Thirty streamflow gauges record flows above flood stage through the US monitoring network Sunday, up from twenty-nine yesterday. WT USA follows the water levels and volume on four of these reference flood events, and all four occurring in the state of Louisiana.
Louisiana: West state border Sabine River got back out of the channel around 9pm Saturday night near Logansport, currently recorded half a foot over minor flood stage running 22600 cubic feet per second. The volume downstream near Bon Wier is 31000 cfs and nine inches over minor flood stage on a steady receding trend. Closer to the Gulf outlet near Ruliff the water level is still more than two feet above the channel and 41600 cfs. Region 1 Bayou Bodcau Lake continues to recede slowly, down another three inches over the last twenty-four hours, currently recorded three and a half feet above the basin near Shreveport. For more info on the flooding in Louisiana, see black tags indicating flood flow volume and gauge height updated daily here.
As many drinking water facilities are supplied from surface water reservoirs, the streamflow situation is pertinent to both drinking water supply and quality. High flows can stir up sediment and cause turbidity in the reservoirs, requiring additional treatments to render the water potable. Low flow volume is linked to warmer temperatures in the reservoir and can be an issue for water quality where HABs are present. WT tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
