MATAGORDA, Texas (AP) — 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. Two people were killed when trees fell on their homes. First responders raced Monday to rescue stranded residents. 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. More than 1,000 flights have been canceled at Houston’s two airports. The National Hurricane Center said damaging winds and flash flooding will continue as Beryl continues pushing inland.
