Flash Flood in San Augustine County, Texas

Flash flooding reported on Highway 2213 and FM Road 705 near San Augustine.

A broad complex of showers and thunderstorms with associated heavy rainfall developed across areas of Deep East Texas and West Central Louisiana by mid to late morning on July 26th. This occurred within an elongated axis of upper-level energy observed along much of the middle and upper Texas coast and up across interior areas of East Texas around the eastern flank of a broader mid-level trough over the Southern Plains. This energy interacted with a very deep tropical air mass and axis of stronger instability that was pooled up across the northwest Gulf of Mexico and farther inland to a lesser extent. MLCAPE values of 1500 to 2500 J/kg were noted across these areas with precipitable water values of 2 to 2.25 inches. As a result, multiple reports of flash flooding were received across parts of Deep East Texas.
