What the reports say
Written by National Weather Service staff at the time of the event · public domain
The extremely heavy rainfall associated with the remains of Tropical Storm Erin moved into Kendall County in the afternoon, producing between 3 and 5 inches over most of the county. Highest rain totals were 8 inches between Boerne and Sisterdale. Most roads in the county were closed and several families had to be evacuated along Cypress Creek due to flooding. City Lake was reported to be only six feet below the spillway. It had only been topped twice in the past 10 years. Near 1900 CST on the evening of April 16, a man and his son were in a truck traveling along FM473 when they attempted to drive across a bridge near FM1376 that was already flooded by Sisterdale Creek. The truck stalled and both men crawled out of the cab through the rear window and stood in the truck bed. Rescuers who arrived within minutes were unable to pass them life jackets or to secure a rope to the truck before a surge of water lifted the vehicle and swept it over the bridge. The father and son were washed into the creek and drowned.
General rainfall of 1 to 2 inches caused brief flash flooding in the area just east of Kendalia. Between 2100 CST and 2130CST, a woman was returning home and while driving on Crabapple Lane in eastern Kendall County and attempted to cross a low water crossing on her drive. The vehicle was apparently washed off the road or partially off the road. Sometime later, her husband noticed the headlights and got in his vehicle to check. He attempted to wade through the water to rescue his wife. Both were drowned in the flood.
A young lady drowned on Cypress Creek near the intersection of Highway 27 and Water Street in Comfort. The car was swept off into the creek due to heavy rain. Two occupants made it to safety. One other occupant drowned and was recovered several miles downstream.
