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.

WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Seventy-six streamflow gauges record flooding in the USA Friday, up from sixty-six Thursday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report, seventeen sites record flooding on the network, four in Georgia, thirteen in Louisiana.
Louisiana is experiencing widespread flooding, under NWS Flood Watch until May 18 with more rain cooming. The view from the USGS monitored sites includes the same twelve sites reported yesterday with the addition of Bayou des Cannes, flood stage breached near Eunice around 5 am this morning in watershed Region 5. Watershed Region 1 Bayou Bodcau is down another three inches, running three feet, seven inches out of the basin near Shreveport. In Region 2, Little River runs close to two feet above the channel near Rochelle, starting to level out. To the south in Region 2, Big Creek is flowing 99th percentile near Pollock. In the southwest, watershed Region 4, Sabine River continues to flood as monitored near Burkeville, Bon Wier and Ruliff stations. Calcasieu River is flooding near Glenmora, Oberlin and Kinder. Tributary Ouiska Chitto is flooding near Oberlin in Region 4. In the east, Pearl River is flooding near Bogalusa and Town of Pearl River, along with tributary Bogue Chitto flooding near Bush. See black tags indicating flow volume and gauge height, blue tags for 99th percentile flows updated daily on the map to the right.
Gulf of Mexico basin is experiencing another monitored flood event in south Georgia/north Florida. Ochlockonee River has breached flood stage near Concord, FL as of late afternoon yesterday, presently recorded three to four inches above flood stage. Suwannee tributary Withlacoochee River continues to flood at Skipper Bridge Rd near Bemiss, GA. On the Atlantic side of the divide, Satilla River continues to overflow at GA158 near Waycross, five inches over flood stage on a level trajectory. Savannah River flooding is ongoing near Cylo, also five inches over the channel on a steady rising trend. See black tags for flood flow details, blue tags for 99th percentile high flows on the map to the right. See black tags indicating flow volume and gauge height, blue tags for 99th percentile flows updated daily here.
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.
