NWS: Scattered thunderstorms in the northwest
June 2, 2024 updated 1046 am CDT
Hazardous Weather Outlook issued by National Weather Service Shreveport forecast center 620 am Sunday June 2
Scattered thunderstorms will be possible today across eastern Texas and northern Louisiana, moving up off the Texas Gulf coast, quickly diminishing with sunset. Then overnight, we may see another complex of thunderstorms arriving in southeast Oklahoma and southern Arkansas by daybreak. Any of these thunderstorms may be strong, but severe storms should be limited to isolated coverage, both today and overnight with lightning, gusty winds and brief heavy downpours.
Isolated to scattered showers and thunderstorms will persist to some extent during the work week. However, the coverage and intensity of thunderstorms should see a decrease each day through Thursday. Then, we can expect another weak cold front to arrive on Friday with more
widespread thunderstorms ending overnight. Then look for a nice weekend for a late spring change of pace.

HABs Tracker
from National Centers for Coastal Ocean Science satellite monitoring program for southeast Louisiana
The latest satellite image of southeast water bodies is mostly clear, captured June 1 at surface wind speed 6.9 mph. Lake Pontchartrain is showing up with the first small open water HABs of the season today at midlake, moderate concentration 100 thousand cells per 100 ml. Chandeleur Sound presents with a widespread area of algal bloom activity east and up to Grand Island matching the color scale for a moderate concentration 200 thousand cells per 100 ml. For more details, see here.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Forty-three streamflow gauges record active floodings in the USA Sunday, Saturday, down from forty-eight Saturday. Two floods occur inside the WT coverage area, both in Louisiana.
Region 5: Vermilion River breached flood briefly Sunday morning at Surrey St in Lafayette, over-running the channel from 3 am until 945 am. Peak flow was reached by 4 am and the flood is already over as of this update. Region 4 flooding continues on the Calcasieu River near Glenmora, currently signalling a gauge height seven inches over the channel on a slow declining trend. Border Sabine River continues to overflow the lower channel in southwest Louisiana this morning, running a level nine to ten inches over minor flood stage. NWS calls for showers in the northwest again today. As the ground is saturated after a week of rain, we could see more surface runoff leading to river flooding. More to follow. See black tags indicating flow volume and gauge height, flows 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.
