Storm hampers travel over Snoqualmie Pass

An incoming storm is causing problems with traffic through the Cascade Mountain passes.

All eastbound Interstate 90 lanes were closed early Thursday morning at Denny Creek due to multiple spinouts and collisions amid heavy snowfall.

The roadway reopened mid-morning and chains are now required in both directions.

A winter storm warning has been issued for the Cascade Mountains above 3,500 feet through 10 p.m. Thursday night.

Ten to 20 inches of additional snow is expected during the storm.  (AP)
