At least 4 killed in severe storms in Houston; power knocked out in Texas, Louisiana

HOUSTON (AP) — Fast-moving thunderstorms pummeled southeastern Texas for the second time this month, killing at least four people, blowing out windows in high-rise buildings, downing trees and knocking out power to more than 900,000 homes and businesses in the Houston area.

Officials urged residents to keep off roads following Thursday's storms, as many were impassable and traffic lights were out. The storm system moved through swiftly, but flood watches and warnings remained Friday for Houston and areas to the east.
