NWS: Flood Watch to 7 pm CDT tonight
June 5, 2024 updated 309 pm CDT
Flood Watch from National Weather Service Shreveport forecast center 652 am CDT Wednesday June 5
Flooding caused by excessive rainfall continues to be possible in Bienville, Bossier, Caddo, Caldwell, Claiborne, De Soto,
Grant, Jackson, La Salle, Lincoln, Natchitoches, Ouachita, Red
River, Sabine, Union, Webster and Winn Parishes of Louisiana. THe flood watch also applies to portions of Arkansas, Texas and Oklahoma through early this evening at 7 p.m.
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. Extensive street flooding and flooding of creeks and rivers are possible. Area creeks and streams are running high and could flood with more heavy rain.
Ongoing thunderstorms this morning will carry into the afternoon heating with heavy down pours possible. See Weather.gov here for more information.
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.
Hazardous Weather Outlook issued by National Weather Service Shreveport forecast center 649 am CDT Wednesday June 5
Showers and thunderstorms are ongoing this morning and into the afternoon, with heating likely to bolster storm strength in the mid to late afternoon for areas along and south of I-20. Damaging winds and hail will be possible along with heavy rainfall at times. In general, additional rainfall totals will be an inch or two on soaked soils, with runoff ponding on roads and poor drainage area. In addition, all this recent rainfall is seeing marked increases on our area rivers, bayous that will linger through the next day at least.
The rest of the work week and the weekend still looks to see the weak cool front become stationary west of I-49, effectively acting as a focus of development for more areas of rainfall. However, we will be warming up as well. The high moisture content in the ground means it will feel even hotter with heat index values in triple digit territory. We can expect our rivers and bayous to see additional rises with minor river flooding issues that may continue into next week.

WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
One hundred and thirty-two floodings are active on the USA network Wednesday afternoon, approximately double the sixty-seven from this morning. Twenty of these floodings are occurring now in Louisiana. USGS streamflow gauges in flood are on a delay uploading the provisional data. Here is what we know now.
Watershed Region 1: Bayou Bodcau Lake and Caddo Lake are flooding near Shreveport and Mooringsport, respectively. Bayou Dorcheat continues to flood near Springhill. To the south into Region 4 watershed, border river Sabine floods near Logansport, runs within a foot of flood stage in action stage near Burkeville, flooding near Bon Wier and near Ruliff. East Region 4 Calcasieu River floods in the upper channel near Glenmora and downstream near Oberlin station. To the east, Region 5 watershed Mermentau River flooding at Mermentau and Vermilion Bay is flooding at Cypremort Point. See black tags indicating flood flow volume and gauge height, blue tags for 99th percentile flows updated daily on the map to the right.
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.
