Major Flood Threat Hits Texas and Gulf Coast as Moisture Fuels Heavy Rain

A multi‑day heavy‑rain event is creating a major flood threat across Texas and parts of the Gulf Coast. Flood watches have been issued for more than 20 million people from central Texas to central Mississippi, with cities such as Brownsville, San Antonio, Houston, Lake Charles and Jackson at risk of life‑threatening flash floods. The Weather Prediction Center has placed a Level 3 (out of 4) flash‑flood threat on the region for each day from Monday through Thursday, and rain totals of 5–10 inches (125–250 mm) are expected. The pattern is being driven by record June moisture, including remnants of Tropical Storm Cristina, and there is a medium chance the system could become the Atlantic season’s first tropical depression or storm, potentially named Arthur, if it moves offshore into the northwest Gulf.

Low‑water crossings are already flooded across several counties. In Bandera County officials are searching for a driver swept away by floodwaters, while crews rescued multiple people trapped in vehicles in Travis, Williamson and Bexar counties. About 80 low‑water crossings were reported flooded in Travis County alone. In Waco, vehicles were stranded on Interstate 35, prompting rescues by Texas Game Wardens. The outlook remains severe, with continued heavy rain expected to produce further flooding and possible coastal impacts.
