Hazardous Weather outlook issued by NWS 518 am Tuesday May 21
Showers and thunderstorms will move into the region late tonight and redevelop across the area on Wednesday afternoon. The rejuvenated showers and storms will bring the potential for strong, damaging wind gusts. Large hail is also possible with the strongest storms.

Current Streamflows, Drought Map from the USGS network in Ohio
Streamflows remain predominantly normal statewide Tuesday, with two more stations reporting below normal measurements overnight. East Fork Little River has picked up flow volume since the initial report Tuesday, no longer the lowest flow rating on the map. Four below normal ratings occur in a line across the Lake Erie basin's east side, including one on the Cuyahoga River nearest the outlet, two below normal in Ashtabula-Chagrin River watershed including the Chagrin River at Willoughby and tributary Conneaut Creek at Conneaut. Grand River is also recorded below normal at Painesville. These monitors are ranked in the top ten most visited monitors in the USGS network of real-time streamflows published in the USA. Three stations claim much below seasonal normal Tuesday, in the Muskingum River basin and on the Shade River near Chester, all three in the southeast. The highest flows in Ohio are 80th percentile recorded on the North Fork of Licking River in the Muskingum basin, and a 75th percentile flow provisionally recorded in a tributary of the Sandusky River in the Lake Erie basin. There are no high flows or flood events recorded as of this report, and no extreme low flows.
Shade River watershed holds the title as the only watershed of 32 in Ohio with a drought rating. Meigs County, south-central Athens, northeast Gallia and south Washington Counties are rated below normal as reported here yesterday.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Exposing the climate contrast as observed in the four states of WT US Bureau, Georgia and Louisiana continue to flood while parts of northern New York state drop into severe drought mode Tuesday. As of this report, sixty-two sites record flooding in the USA with nineteen of these being inside the WT coverage area. Georgia has taken on another monitored flooding location, going from eight to nine overnight. Louisiana has retired one flood event today since the first report this morning, down to ten active floodings.
Georgia: Flooding has expanded in the Atlantic Ocean basin, flooding observed at a fourth location in the Satilla River watershed overnight. Flood stage was breached on the Satilla River near Waycross around 230 am this morning, this flow currently recorded at three inches above the channel and rising. By the time Satilla River reaches the monitor near Waycross, it is armed with the surface runoff from an area of 1240 square miles of south Ben Hill, east Irwin, Coffee, west Pierce and north Ware Counties. This water is now measured at over sixteen feet deep, running a provisional measurement of 6680 cubic feet per second Three more streamflow monitors record flooding in the area including one station upstream on the Satilla River at GA 158, and two tributaries, the Alabaha River flooding at GA203 near Blackshear and Little Satilla River flooding near Offerman. Also in the Atlantic basin, Savannah River has leveled off a foot and a half above the channel near Cylo. Across the state divide into the Gulf of Mexico basin, Ochlockonee River continues to spill over at GA188 near Coolidge and downstream near Concord, FL. Withlachoochee River remains above flood stage at Skipper Bridge Rd near Bemiss and at US84 near Quitman. See black tags indicating flow volume and gauge height, blue tags for 99th percentile flows updated daily here.
Louisiana has retired another flood site this morning. Region 2 Little River is no longer flooding near Rochelle. Ten flood events remain on the radar for LA late Tuesday morning. Region 4 Sabine River continues to run four feet over the channel near Bon Wier, TX and three feet, three inches over near Ruliff, TX. Calcasieu River continues to overflow a foot and nine inches over the channel in the upper basin near Glenmora, currently recorded on a steady declining flow trend. The moderate flood status of Calcasieu River has just passed, dropping into minor flood stage around 9 am this morning near Oberlin. Flooding near the downstream monitor near Kinder runs two feet above the channel, on the decline. Elsewhere in Louisiana, Region 1's Bayou Bodcau continues a slow descent presently two and a half feet out of the basin near Shreveport. Watershed Region 5 flooding carries on at LA-190, Bayou Nezpique runs nine inches over minor flood stage near Basile with Mermentau River flooding to the south, still more than half a foot over at Mermentau. In Region 7, Pearl River runs a foot and three inches out of the channel at both stations, near Bogulusa and at the Town of Pearl River. See black tags indicating flow volume and gauge height, blue tags for 99th percentile flows 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.
