Survivors have described the floods along the Guadalupe River as a “pitch black wall of death” and said they received no emergency warnings.

Heavy rainfall has overwhelmed multiple low water crossings and areas along the Guadalupe River, local authorities reported.

The death toll included 18 adults and 14 children. Gov. Greg Abbott's disaster declaration now includes Bexar County.

Former federal officials and outside experts have warned for months that President Donald Trump’s staffing cuts to the National Weather Service could endanger lives.

"A lot of the weather forecast offices now are not operating at full complement of staff," said the former lead of NOAA.

Texas forecasters issued a series of early-morning warnings about “life-threatening flooding” along the Guadalupe River.
