Isolated severe thunderstorms possible
NWS: Damaging wind gusts for Central Georgia
Water news for Monday, May 13, 2024 902 am EDT
National Weather Service Hazardous weather outlook issued 428 am EDT May 13
A couple isolated severe thunderstorms are possible in central Georgia today or tonight. The primary hazard with any storms should be damaging wind gusts.
Isolated severe thunderstorms may develop in Georgia Tuesday afternoon and evening. Where storms occur, the hail and damaging wind gusts will be the main concerns. Additional thunderstorm activity may occur Wednesday, Friday, Saturday or Sunday. Locally heavy rainfall may produce isolated flooding and or rising river and stream levels in the region through Sunday.

Current Streamflows, Drought Map from the USGS network in Georgia
Streamflows run above 90th percentile through the Flint, Ochlockonee and Suwannee watersheds heading for the Gulf of Mexico Monday. Northwest Georgia flows feeding the Mississippi River run above the 95th percentile with Coosawattee River running above the 99th percentile Monday. The Atlantic drainage basin flows are normal in the upper basin increasing to above normal rating downstream in Savannah and Ogeechee watersheds, seasonal normal end to end for Altamaha, Satilla and St. Marys watersheds. No part of Georgia is rated on the drought map, no low flows recorded in the network.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Sixty two streamflow gauges record flooding in the USA Monday morning, up from Fifty-seven Sunday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, five sites record flooding on the network, all in Louisiana.
NWS is calling for more thunderstorm and rain activity in central state this week with potential for localized heavy rains and flooding where the ground is already saturated. As of this report, there are no active floods registering on the network. Coosawattee River records 99th percentile flow near Carters with a declining flow trend.
See the blue tags for high flow 99th percentile volume updated daily on the map to the right.
Louisiana posts the same five stations running above flood stage again going into Monday as reported the past week. Region 4 watershed Sabine River is up overnight, running more than two feet above the channel near Bon Wier. Downstream near Ruliff, the flooding continues a foot and a half above the channel. Calcasieu River is also up, more than a foot over flood stage near Glenmora. In Region 1, Bayou Dorcheat continues on a declining flow trend, flowing nine inches over flood stage near Springhill. Bayou Bodcau has maintained a level four and a half feet above the basin near Shreveport for the last twenty four hours. See black tags on the map 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.
