Thunderstorms this afternoon in the northwest
June 19, 2024 938 am CDT
Hazardous Weather Outlook issued 538 am June 19 by Shreveport forecast office
Scattered showers and a few thunderstorms are expected this afternoon as tropical moisture continues across the region. The strongest storms may contain gusty winds and brief heavy rainfall, but organized severe weather is not anticipated.
Rain chances will disappear as upper ridging builds over the region on Thursday. The potential for temperatures posing a heat risk will exist through the weekend and into next week.

Current Streamflows from the USGS network of gauges in Louisiana
Above normal to much above normal streamflows recorded in the west midweek with an area closer to the Mississippi border continuing to experience a drying trend and much below normal streamflows. Over to the east state area, streamflows run mostly normal with a single rating much below normal sticking on Tangipahoa River at Robert. The drought map has three spots locked in today, Region 3 Tensas River channel takes the lead at extreme drought, Region 7 Tangipahoa Parish in second spot with another day of severe hydrologic drought. New on the drought dashboard Wednesday is a below normal rating applied to the Amite River channel east into East Feliciana and East Baton Rouge Parishes and west into St Helena and Livingston Parishes.
From The Sensors provisional data on river flooding from the network of USGS streamflow monitors
Twenty-seven streamflow gauges placed in reference locations throughout the USA record flows above flood stage today. This is an increase from twenty-three yesterday. WT USA tracks the flow levels on four of these reference flood events, as the sensors read it, all occurring in the state of Louisiana.
Louisiana: Coastal flooding Vermilion Bay got above flood stage around 6 am this morning near Cypremort Point currently recorded three inches above flood stage and rising. Ongoing since June 4, Region 1 watershed's Bayou Bodcau Lake continues to flood the basin near Shreveport in Region 1, down six inches overnight and currently recorded at two feet and four inches above minor flood stage. In Region 4, west boundary river Sabine water level has peaked and started to recede near Logansport, currently recorded a foot and seven inches over minor flood stage. Flow volume has slowed for the first time in days, from over 27000 cubic feet per second yesterday to 26000 this morning. Downstream near Ruliff the water level is down three inches over the last twenty four hours, Sabine River currently running a foot and one inch over the channel, flow volume has dropped overnight from 27000 to 22000 cubic feet per second. 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.
