The team deployed around 7 a.m. Friday from Corpus Christi, about 200 miles south of where the Guadalupe River in Kerr County, Texas, had risen from about 3 feet to nearly 30 feet.

Parts of the state devastated by flash floods that left at least 82 dead were braced for more heavy rains as forecasters extended flood warnings through Monday evening.
