Massive Storm to Test Power Grids Across US This Weekend

Snow and dangerously bitter cold are spreading from the Rocky Mountains to the Great Lakes as a massive storm pushes toward the US Northeast, disrupting travel and threatening power outages for much of the nation. The storm is expected to span nearly 1,500 miles (2,400 kilometers), bringing heavy snow, crippling ice and subzero wind chill to some of the biggest US cities. Natural gas prices surged on concern iced-over equipment will choke supplies. Airlines have already canceled almost 4,000 flights and Amtrak has pulled dozens of trips from its schedule.
