 Tropical Storm Beryl was unleashing heavy rains and powerful winds along the Texas coast, knocking out power to more than 2 million homes and businesses and flooding streets with fast-rising waters. First responders raced Monday to rescue stranded residents, and police in the Houston suburb of Rosenberg urged residents to stay off the roads after one of their high-water vehicles was hit by a falling tree while returning from a rescue. Houston Mayor John Widmere says most of the city got 10 inches of water.
