Shreveport, La. – Heavy rainfall across the ArkLaTex this weekend may trigger flash flooding in multiple states.
According to the National Weather Service in Shreveport, showers and thunderstorms will move into the region Saturday and continue through Saturday night, bringing a flash flood risk across Southwest Arkansas, Northern Louisiana, and portions of extreme Northeast Texas.
Forecasters indicate at least a 15% chance of flash flooding within the highlighted risk area. Widespread rainfall totals of 1 to 2 inches are expected, with isolated amounts exceeding 3 inches possible, especially along and north of the Interstate 20 corridor.
The Weather Prediction Center has outlined a marginal to slight risk (Levels 1 and 2 of 4) for excessive rainfall across much of the Four-State Region. Areas including Texarkana, El Dorado, Ruston and Monroe fall within the higher-end risk zone.
Flash flooding can occur when intense rainfall overwhelms drainage systems, particularly in urban or low-lying areas. Roadways near creeks, bayous and underpasses may become impassable if heavy rain develops repeatedly over the same location.
Travelers along Interstate 20 and surrounding highways should monitor changing conditions, particularly Saturday evening into early Sunday when rainfall rates may peak. Young drivers and weekend commuters are urged to remain alert for rapidly changing roadway conditions.
Residents are advised to monitor updated forecasts and ensure they have multiple ways to receive weather alerts.
The threat is expected to diminish by late Sunday morning as storms shift eastward.
