Wider weather episode

An upper level area of low pressure combined with deep boundary layer moisture to produce a slow moving mesoscale convective system. This MCS produced excessive rainfall from Atascosa to Comal counties. CoCoRAHs observers reported 7.81 inches of rain near Pleasanton and 11.30 inches near New Braunfels. Heavy rain began shortly after midnight over portions of southern Comal County. Heavy rains in excess of 11+ inches fell in the area centered between the Guadalupe River and Highway 46 between 2 am and 8 am. This runoff produced a massive flash flood along the Guadalupe primarily downstream of the 3rd river crossing. Hardest hit areas were the campsites along River Road and areas directly along the riverbank in Gruene, New Braunfels, Lake Dunlap, Lake McQueeny, and Seguin. Total losses are estimated into the 10s of millions of dollars. One death occurred with several swift water rescues. Dozens of campers, vehicles, and boats were lost in the resulting flood along the Guadalupe.
