Scattered showers, thunderstorms
June 18, 2024 1249 pm CDT
Hazardous Weather Outlook issued 453 am June 18 by Shreveport forecast office
Scattered showers and a few thunderstorms are expected this afternoon through the early evening as tropical moisture continues to increase across the region. The strongest storms may contain gusty
winds and brief heavy rainfall, but organized severe weather is not anticipated.
Impacting Caddo-Bossier-Webster-Claiborne-Lincoln-De Soto-Red River-Bienville-Jackson-Ouachita-Sabine-Natchitoches-Winn-Grant-Caldwell-La Salle Parishes.
Current Streamflows from the USGS network of gauges in Louisiana
Scattered showers forecast in the flooding area today will maintain the northwest streamflows above normal to much above normal. The trend drops as you move east, into Region 3, two monitoring stations are recording much below normal water levels. In east Louisiana, the streamflows run mostly normal with a much below normal rating applied to Tangipahoa River at Robert. Region 3 Tensas River channel holds on to extreme drought rating again overnight with Region 7 Tangipahoa Parish rated severe hydrologic drought.
WT USA Flood Tracker provisional data from the network of USGS streamflow monitors
Twenty-three streamflow gauges record flows above flood stage in the US Tuesday, the same as yesterday. WT USA tracks the flow levels on three of these reference flood events, all occurring in the state of Louisiana.
Louisiana: Bayou Bodcau Lake continues to flood the basin near Shreveport in Region 1, now two feet ten inches above minor flood stage. In Region 4, west boundary river Sabine water level is up four inches overnight near Logansport, currently recorded a foot and eight inches over minor flood stage. Flow volume has been increasing here the last few days, from 23000 cubic feet per second Sunday to 26000 cfs Monday to now more than 27000 Tuesday. Downstream to the station near Ruliff, the Sabine River runs a foot and four inches over the channel, also at 27000 cfs. For more info on the flooding in Louisiana, see black tags indicating flood flow volume and gauge height 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.
