The first weather emergency alert sent by the National Weather Service with urgent language instructing people to "seek higher ground now" was sent at 4:03 a.m. local time.

Kerr County Sheriff Larry Leitha was unable to answer direct questions about who was in charge and whether they were asleep early Friday morning when the Guadalupe River burst its banks.

A small Texas town that recorded no deaths in last weekend’s flood disaster had recently upgraded its emergency alert system — the kind of setup state, county and federal officials
