June 17, 2024 1114 am CDT
Hazardous Weather Outlook issued 446 am June 17 by Shreveport forecast office
Scattered showers and thunderstorms will be possible this afternoon and early evening as tropical moisture increases across the local area.
More widespread showers and thunderstorms are expected areawide through Wednesday. The greatest coverage of showers and thunderstorms will generally be from the early afternoon through the evening each day. Locally gusty winds and brief heavy rainfall will be possible in the stronger storms, but organized severe weather is not anticipated.

Current Streamflows from the USGS network of gauges in Louisiana
With showers in the northwest, streamflows remain much above normal to high Monday. Much below normal flows are still recorded in Regions 3 and 7 contributing to the same action on the drought map as reported here yesterday, Region 3 Tensas River channel occupies the extreme drought category another day while Tangipahoa Parish languishes in severe 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 Monday, down from thirty yesterday. WT USA follows the water levels and volume on three of these reference flood events, all occurring in the state of Louisiana.
Louisiana: West state border Sabine River flooding near Bon Wier ended yesterday afternoon. Upstream near Logansport the flow is up overnight, currently recorded a foot and four inches over minor flood stage at increased flow volume, from 23000 to now flowing over 26000 cubic feet per second. Near Ruliff the Sabine River a foot and nine inches above the channel flowing 33 thousand cubic feet per second. Region 1 Bayou Bodcau Lake continues to recede, down five inches overnight, currently recorded three feet and an inch above the basin near Shreveport. For more info on the flooding in Louisiana, see black tags indicating flood flow volume and gauge height updated daily here.
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.
