What the reports say
Written by National Weather Service staff at the time of the event · public domain
Thunderstorms produced heavy rain that led to flash flooding. Based on radar estimates, 8-11 inches of rain fell in a three hour period across northwestern Uvalde County. Many low water crossings flooded across this area, and Highway 55 was closed from Uvalde to Camp Wood. A flood wave traveled down the Nueces River and through the Chalk Bluff camp ground. Several people from the camp ground became stranded in trees and on roof tops of vehicles, and some were reported swept downstream. Twenty-seven people were successfully rescued from the flood waters by boats and helicopter. One person was treated for a head injury and two children were treated for hypothermia. Estimated monetary loss of one hundred thousand dollars based on flooded cars and trailers that were lost downstream.
As the showers and thunderstorms spread into Uvalde County from the west, they produced a general 1 inch rainfall, with widespread 2 inch amounts over the eastern part of the County. Isolated locations in the east central part of the County reported up to 4 inches of rain. Flash flooding began in the early morning hours and continued until nearly noon. Damage was mainly to roads and bridges in the eastern part of Uvalde County.
