Torrential rain causes flash flooding in Houston

Severe weather hit the Houston area Monday, flooding streets and homes and leaving thousands of people without power, emergency officials said. Torrential rain fell across the area, causing flash flooding that left streets and highways impassable and submerged some vehicles. "We have a lot of roadways closed, and some evacuations are going on," said Alan Spears of the Fort Bend County office of emergency management. In the city of Richmond, rescues were conducted by boat and on foot. Spears said he believes a tornado touched down in the area.
