What happened

The episode as NWS SJT wrote it up.

After causing flooding across sections of the Northwest Hill Country on the 23rd, the remnants of Tropical Storm Charley continued drifting westward. The heaviest rainfall and most extensive flooding developed across the Northern Edwards Plateau and Southern Concho Valley on the morning of the 25th. Across Crockett, Schleicher, Sutton, and Irion counties, rainfall totals of 6 to 12 inches would fall in just a few hours. Flooding was widespread, with most roads flooded and impassable. Evacuations were begun in Sonora in Sutton County, when the Dry Devils River and Lowery Draw quickly climbed out of their banks.
