National Weather ServiceFlood Watch issued 401 am Thursday May 16
FLOOD WATCH IN EFFECT FROM THIS EVENING THROUGH SATURDAY MORNING
Flooding caused by excessive rainfall continues to be possible in portions of southeast Louisiana and southern Mississippi.
Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas.
Multiple rounds of storms will be moving through the area beginning tonight and continuing into Saturday morning. Three to six inches of rainfall with locally higher amounts will be possible, enhancing the flash flooding threat. Monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Sixty-six streamflow gauges record flooding in the USA Thursday, down from sixty-seven earlier today. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, fifteen sites record flooding on the network, three in Georgia, twelve in Louisiana.
Louisiana flooding increased from eight to ten locations yesterday with three new locations flooding since our last update. In the east, Region 7 watershed Pearl River set to flooding near Bogalusa around 8 am yesterday morning, this flooding extends downstream to the Town of Pearl River as of around the 9pm hour last night. Pearl River tributary Bogue Chitto breached flood stage this morning around 230 am near Bush. Watershed Region 4 Calcasieu River continues to flood in the upper channel near Glenmora and mid-channel Oberlin. Flood stage was breached yesterday afternoon downstream near Kinder, currently running extends further downstream to the monitor near Kinder, currently running a foot and nine inches over, this flow appears to have peaked in minor flood stage, presently on a slow declining curve. In watershed Region 4, Sabine River flooding is recorded near Burkeville, near Bon Wier, and downstream near Ruliff, TX. Bayou Anococo flooding ended around 4 am this morning near Rosepine. Watershed Region 1 Bayou Bodcau continues a slow decline, down a few inches overnight near Shreveport, currently registering just under four feet out of the channel. In Region 2, Little River floods on near Rochelle, still rising. See black tags indicating flood flow volume and gauge height, blue tags for 99th percentile flows updated daily on the map to the right.
Georgia river flooding is up to three monitored sites overnight. Suwannee tributary Withlacoochee River has reached peak flow and is receding, presently recording a foot and a half above flood stage at Skipper Bridge Rd near Bemiss in the Gulf of Mexico basin. On the Atlantic side of the divide, Satilla River breached flood stage at GA158 near Waycross Wednesday evening, recorded Thursday at five inches over flood stage and rising. Savannah River is flooding near Cylo, flood stage breached around 3 am this morning, presently recorded less than an inch over the channel. See black tags for flood flow details, blue tags for 99th percentile high flows on the map to the right.

Drinking Water Advisories
St. Landry Parish: City of Opelousas issued a BWA on Tuesday for customers connecting north of Martin Luther King Drive from Hwy 182 North to Magnolia, Linus, and Gerry streets.
Calcasieu Parish: Moss Bluff came under a BWA following a water line repair Tuesday, according to Water District 1. Customers impacted include Peridot Lane, Misty Lane, Jonquil Lane, Larkspur Drive, Caravelle Drive, Bellview Drive, Concord Drive, Amber Drive, Augustine Drive, Sabre Drive, Gateway Drive and Belfield Road.
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.
