Gov. Chris Gregoire has declared a state of emergency for an ice storm that landed on top of heavy snow in western Washington, causing treacherous travel, power outages and threats that buildings could collapse. So far, the storm has left more than 200,000 people without power.
Seattle city officials are asking residents to get home before dark, if possible, because they fear even worse icing conditions by night fall.
Ice closed Sea-Tac Airport in the early morning before one runway was reopened. The State Patrol said it had responded to about 2,300 accidents in a 24-hour period ending at 9 a.m. Thursday, roughly quadruple the average number.
