May 23, 2024 updated 1017 am CDT
Hazardous Weather outlook issued 353 am Thursday May 23
This Hazardous Weather Outlook applies to north central Louisiana, northwest Louisiana:
Strong to severe thunderstorms will be possible once again today, into the evening and overnight hours across much of the Four State Region. Large hail, damaging thunderstorm wind gusts and locally
heavy downpours will be the primary threats with an isolated tornado threat as well. The severe weather threat should end from northwest to southeast across the Four State Region overnight tonight. While
widespread flooding is not likely through tonight, flooding of low lying and flood prone areas will be possible with heavy downpours through tonight.
Severe weather will be possible once again late Friday into Friday Night and late Saturday into Saturday Night across mainly portions of Northeast Texas, Southeast Oklahoma and Southwest Arkansas. Large
hail and damaging thunderstorm wind gusts will again be the main threats Friday and Saturday.
Spotter activation will be possible later today through this evening.

WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
As of this report, sixty sites record flooding on the USGS network through the USA with fifteen occurring in WT coverage area. The nation's most common disaster is recorded through south Georgia, presenting a sample of nine stations recording flooding. Louisiana has dropped two active river flooding sites overnight, currently recording seven flood events in the network.
Louisiana has retired a river flood event overnight in watershed Region 4. West border Sabine River is back in the channel near Bon Wier, TX as of 615 am CDT this morning. Sabine River flooding is down to one station in the lower channel near Ruliff, running two feet four inches over flood stage. To the east in the Calcasieu River, the station near Oberlin records flooding ended around 145 am CDT this morning. The stations upstream and downstream of Oberlin on the Calcasieu River are still flooding, running more than a foot over near Glenmora and downstream runs four inches over flood stage near Kinder. Region 5 watershed has one river flood event Thursday, Mermentau River runs five inches over at Mermentau. Region 1 watershed's Bayou Bodcau continues the steady decline curve, running a foot and five inches above the basin, even after a night of rain in the region. NWS forecast locally heavy downpours last night that Bayou Bodcau could have picked up over 668 square miles of east Bossier Parish and southwest Arkansas. In Region 7, Pearl River is up again overnight, running a foot and ten inches above flood stage near Bogalusa. Flow downstream at the Town of Pearl River runs less than a foot over flood stage at the Town of Pearl River. See black tags indicating flow volume and gauge height, flows updated daily on the map to the right.
Georgia: River flooding has shifted overnight on both sides of the state divide. In the Atlantic basin, Satilla River tributary Alabaha River rested down into the channel around 1130 pm last night at GA203 near Blackshear leaving Satilla River flooding at three locations, at GA 158 near Waycross, downstream at another location near Waycross and downstream at Atkinson. Tributary Little Satilla runs a foot over the channel near Offerman. Savannah River held a level flow overnight, still a foot and three inches above the channel. In the Gulf Basin, flooding has expanded in the Suwannee River watershed. Withlachoochee River is recorded flooding at three monitors Thursday, running more than a foot over flood stage at Skipper Bridge Rd. near Bemiss, close to four feet above the channel at US84 near Quitman and downstream near Pinetta, FL. Flood stage was breached near Pinetta, FL around 10 pm last night, currently registering a provisional reading one foot above flood stage and rising. Ochlockonee River is still flooding a foot over near Concord, FL. See black tags indicating flow volume and gauge height, updated daily here.
Drinking Water Advisories
Calcasieu Parish Waterworks District 1: Moss Bluff came under BWA Tuesday May 21 due to loss of pressure in the water lines. Customers connecting at Park Rd from Pinecone Dr to Waynewood Drive, Stafford Road from Drain Ditch to Park Road, Empress Drive, West and East Bristol Drive and New Castle Drive are impacted. The boil order is in effect until further notice.
See more current drinking water advisories on the map to the right, yellow tags.
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.
