What the National Weather Service wrote

Training of numerous cells over Seminole and areas to the east and northeast caused widespread and extensive flooding. The KMAF 88D Storm Total Precipitation measured a strip of 20 by 8 miles that received in excess of 5 inches of rain. Readings from within the swath confirmed this estimation. Residences were flooded in Seminole and cars on FM 1429 east of Seminole were stranded in high water. One new mobile home east of the city became flooded and started to float in the water, only to break apart shortly thereafter. Several people were rescued from vehicles standing in 4-5 feet of water. Numerous animals died in the event, including five horses on a farm that died from hypothermia after being stranded for hours in deep, hail-chilled waters.
