Roofs began to creak and collapse under the weight as another storm Thursday added to epic snowfall in western New York state. The three-day snowfall total reached 6 feet (1.8 meters) or more in the Buffalo area, AP reported. New York Gov. Andrew Cuomo implored residents stay off slippery, car-clogged roads for another day as crews rushed to dig out. Some areas received close to 2 feet (0.6 meters) of new snow by Thursday afternoon. The wild card was an expected weekend warmup with rain â€" raising the specter of flooding and yet more weight pressing down on roofs, where the snow could absorb the rain like a blanket. Roof collapses were reported around the region, including cave-ins that prompted the evacuation of 15 to 20 people Thursday from a suburban Buffalo mobile home park. Homeowners and store employees climbed onto roofs to shovel off the snow and reduce the danger. The immediate concern Thursday was recovering from the 5 feet (1.5 meters) or more of snow that fell earlier in the week. National Guardsmen drove nurses to work their hospital shifts. State troopers helped elderly residents trapped in their homes. State officials assembled 463 plows, 129 loaders, 40 dump trucks from across the state. -- SPA 22:44 LOCAL TIME 19:44 GMT تغريد
