Hundreds of emergency crews battled Monday to clear snow-clogged roads and restore power to thousands of homes across the US east coast before a new storm hits. But despite their best efforts, the US capital remained largely paralyzed, with the federal government announcing it will remain closed for at least one more day and scores of schools and local businesses remaining shut down. An early morning freeze on Sunday, which had turned partially cleared highways into icy skating rinks, gave way to warmer temperatures helping the big melt to get under way, but officials warned travel was still hazardous. With record snowfall of more than three feet (a meter) in many places after a monster blizzard swept across Virginia, Maryland and the US federal capital city, bulldozers were having to move in. The record snowfall for a storm dubbed "Snowmageddon" was registered in a small town of Colesville, central Maryland, which was blanketed by 40 inches (101 centimeters), the National Weather Center said. Virginia police had turned out to more than 4,370 calls, with most being traffic crashes or stranded cars. It is believed only three people died as a result of the storm. Reagan domestic airport was still closed Sunday, and there was little likelihood of flights out of the international airports at Baltimore, or Dulles, bogged down by a record 32.4 inches (82 centimeters) of snow. Schools were to remain closed on Monday and Tuesday across most of the region as were local government offices across a swath of northern Virginia and Maryland, at least on Monday. And forecasters warned yet another front was moving across from the west coast, prompting the National Weather Service to issue a winter storm watch around the capital. As many as 40 above-ground metro stations will remain closed another day, authorities announced, while buses will resume limited service only along the city's main thoroughfares -- and only between 9:00 am and 7:00 pm.
