The ice storm is already blamed for eleven deaths, and the bad weather means people traveling out of Sea-Tac Airport should check their flights.
People arriving also face delays, but on Monday they were glad to get out of the winter weather. Cecilia Rakonza flew out of Oklahoma City just in time to visit her granddaughter for Thanksgiving.
"I'd sure hate to get stranded you know," she said. "We've got snow and ice and everything. Yeah, I was kind of worried about leaving you know."
Rakonza said she's lucky to get out of the Midwest, which is dealing with it's own travel problems. Many flights have already been cancelled, including hundreds in and out of Dallas-Fort Worth.
The East Coast is getting rainfall and snow is in the forecast for Pennsylvania and New England. Most flights out of Sea-Tac did not face huge delays on Monday. But, several were later getting in due to weather.
