A huge storm that slammed the Texas Panhandle on Monday and moved north on Tuesday is already being blamed for two deaths—and it’s showing no signs of stopping. In Oklahoma, one man was killed after his roof collapsed under 15 inches of snow. The storm also killed a motorist in eastern Texas, where some areas saw record accumulations of snow. Hurricane-force winds also whipped Texas, Oklahoma, and Kansas, knocking out power to thousands. Fueled by a low-pressure system, the storm didn’t just dump snow: it also caused thunderstorms, and tornado watches were issued in Arkansas and Louisiana. It gets worse: up to 15 inches of snow were expected in Missouri, which was slammed by a blizzard just five days ago.
