The Problem With ‘Move to Higher Ground’
Before the waters of Texas’s Guadalupe River rose more than 33 feet over the course of five hours, the National Weather Service sent out a series of alerts. The first one that included Kerr County, where most of the fatalities would ultimately take place, warned of “considerable” flood threat and went out just after 1 a.m. on July 4. It triggered push alerts on people’s phones. It set off alarms on any weather radio tuned to the National Oceanic and Atmospheric Administration’s frequency.
