A record setting snowstorm, followed by a layer of ice has caused by problems for Seattle and much of the Northwest. Here's the lead from an AP story:

A monster Pacific Northwest storm coated the Seattle area in a thick layer of ice Thursday and brought much of the state to a standstill, sending hundreds of cars spinning out of control, temporarily shutting down the airport and knocking down so many trees that members of the Washington State Patrol brought chain saws to work.

This view of the storm is from the hill in the 400 block of South Washington Street that runs in front of Engine 10 and Ladder 1's quarters. Seems to be some wheels locking up on cars and fire trucks. The video was shot by Dirk Steinhardt (more apparatus videos from Dirk). Here's part of his description:

The decision was taken to mount snow chains on all of the rigs when all of a sudden a call came in. Engine and Ladder of station 10 were dispatched to a MED7 medical call together with a medic unit. A MED7 means that at least 7 persons need to be on the scene and usually it would be a CPR in progress
