Emergency responders in San Antonio are trying to find a man who was swept away in a flooded drainage ditch while walking a dog.
Authorities say the dog was walking close to the canal when the man, while trying to pull the pet back, fell into the water overnight. Firefighters retrieved the dog but were unable to locate the man, as a rainstorm soaked parts of San Antonio.
Elsewhere in the rain-drenched state, a Union Pacific freight train derailed near Corsicana, about 50 miles south of Dallas, because a creek overflowed and washed away the tracks. A railroad spokesman said the two crew members swam to safety and nobody was hurt.
Authorities have reopened a section of Interstate 45 near Corsicana that was closed overnight due to flooding, backing up traffic for 12 miles.
The National Weather Service says Corsicana has received more than 18 inches of rain since Friday morning. The town of Powell, just east of Corsicana, had more than 20 inches of rain.
Many parts of Texas, including its biggest cities, are under flash flood watches through Sunday or Monday.
