 Live from NPR News in Boston, I'm Steve Brown. Hurricane Beryl has been downgraded to a tropical storm after sweeping into Texas as a Category 1 hurricane with heavy rains and powerful winds. Beryl knocked out power to at least 1.5 million homes and businesses as fast-rising waters caused street flooding and prompted rescues. More than 1,000 flights have been canceled at Houston's two airports because of the storm.
