Major Flash Flood Threat from Texas to the Mississippi Valley, Including Houston, Fueled By Tropical Moisture

Dangerous flash flooding is possible today in parts of Texas and Louisiana as tropical moisture streams northward from the Gulf of Mexico. The potential for flooding will continue through the end of this week in other parts of the South as an area of low pressure sluggishly moves through the region. A "high risk" of flash flooding has been issued by NOAA's Weather Prediction Center (WPC) for Wednesday and Wednesday night along the upper Texas coast and in southwest Louisiana, including Houston and Lake Charles, Louisiana. Rainfall rates of 1 to 4 inches per hour are possible in showers and storms that spread through this region, likely triggering flash flooding.

A broad area from eastern Texas and eastern Oklahoma through the lower Mississippi Valley to the Southeast will see at least 1 to 3 inches of rain through the weekend. Locally 6 inches or more of rain is possible in areas where clusters of thunderstorms stall for several hours at a time. The National Weather Service has issued flash flood watches from the upper Texas coast into southern Louisiana and far southern Mississippi. This includes Houston and New Orleans. Additional flash flood watches could be issued for other areas in the South where heavy rain is expected the next several days. A large area from eastern Texas and eastern Oklahoma into Louisiana, Mississippi, Arkansas, Alabama, southwest Tennessee and the western Florida Panhandle could see locally flooding downpours. This soaking weather pattern will wring out more rain in the Southeast through the weekend, potentially contributing to additional flooding problems.
