SEATTLE — Drivers were asked to take it slow on their morning commute Monday amid a Dense Fog Advisory impacting most of western Washington.
The advisory expired at 10 a.m. Monday morning.
The fog was expected to lead to hazardous driving conditions in a large portion of the region. Visibility was at or below a quarter of a mile for much of the Puget Sound area, including Everett, Seattle, Tacoma, Olympia, Port Townsend, Bremerton, Port Orchard and the San Juan Islands - and also farther west and south, into Hoquiam, Centralia, Toledo and Tenino.
Drivers were asked to take extra precautions when they left Monday morning, including making sure headlights are on, leaving extra following distance between themselves and other cars, and going slower than they would on a typical commute.
KING 5 activated First Alert for this weather event, which could affect lives, property or travel in the Pacific Northwest region. During this event, the First Alert Weather Team will bring you the latest information to keep you and your family safe.
Low temperatures near freezing in some areas also produced some pockets of freezing fog, according to the National Weather Service (NWS). Conditions are expected to slowly improve by early afternoon.
Fog is expected to develop in the mornings through mid-week, clearing into mostly sunny conditions with near-normal temperatures in the afternoons.
Later this week, a new system will arrive bringing warmer temperatures and rainfall on Thursday and Friday. A cold front is expected to arrive on Saturday and last through the weekend.
