Heat index spikes, isolated thunderstorms for north and central GA
June 15, 2024 1030 am EDT
Hazardous Weather Outlook issued 338 am June 15 from National Weather Service forecast center in Peachtree City
Heat index values between 98 and 104 degrees are expected in northern and central Georgia today. This level of heat may affect anyone without access to adequate hydration or effective cooling. Isolated thunderstorms are expected between 2 PM and 10 PM in northern and central Georgia. Isolated damaging winds could occur,
but widespread severe weather is unlikely.

Current Streamflow Situation from the USGS network of streamflow gauges through Georgia
An even mix of normal and below normal ratings Saturday as a heat dome rolls in to north and central state. The highest flow values recorded today are 95th and 93rd percentile on tributaries of the Coosa River watershed in the northwest. A 2nd percentile low flow on the Chattahoochee River near Columbia, Alabama is the single low flow rating today. Chattahoochee River is clear of the drought map Saturday, leaving Tallapoosa and Flint watersheds below normal on the Gulf side of the divide. On the Atlantic side, we have the Satilla River watershed coming on at below normal from south Appling to northeast Pierce and west Wayne Counties. Lower Ocmulgee River watershed remains below normal from south Laurens County, west Wheeler, east Dodge and north Telfair Counties; and Brier Creek channel is still rated below normal through south McDuffie, north Glascock, central Burke and central Screven Counties in the Savannah River watershed.
WT USA Flood Tracker provisional data from the network of USGS streamflow monitors
Twenty-nine streamflow gauges record flows above flood stage through the US monitoring network Saturday, down from thirty-two yesterday. WT USA follows the water levels and volume on three of these reference flood events now, and all three pertain to the state of Louisiana.
Louisiana: Sabine River flooding continues, down two feet overnight near Bon Wier, still two and a half feet above flood stage, overflowing about the same measure above flood stage near Ruliff. Region 1 Bayou Bodcau Lake is settling down slowly, down three inches overnight, presently three feet nine inches over 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.
