The National Weather Service has issued a dense fog advisory for the Tri-Cities and has extended the air stagnation advisory through 10 a.m. Tuesday.
However, the end to the inversion over the Mid-Columbia and persistent fog may be in sight. The weather service predicts that a change in the weather pattern could bring some precipitation and an end to stagnant conditions Wednesday.
But until then, expect dense or patchy fog in the Mid-Columbia, possibly freezing on roadways overnight.
The National Weather Service issued a high wind warning in Tacoma, Olympia and Shelton through noon today.
People in Whatcom, Skagit and Island counties are being asked to refrain from burning wood this week because of stagnant air that is lowering air quality.
The National Weather Service expects a stagnant air mass to linger over the area into the early part of next week. The weather pattern is likely to cause hazardous conditions in Columbia Valley, where air quality is often worse because nearby mountains trap pollution close to the ground, according to the Northwest Clean Air Agency. When conditions are hazardous, people should stay indoors with windows and doors closed and limit physical activity.
Based on monitors in Bellingham and Anacortes, the agency is forecasting air quality may remain in the moderate range in some areas during this period. Sensitive groups with lung or heart disease, diabetes or respiratory infections, and people who have had a stroke should consider limiting outdoor activity.
The cold, dry weather and freezing fog that has made roadways slick and dangerous in the morning will continue into the middle of next week in Whatcom County, the National Weather Service said.
Expect overnight lows near 30 and daytime highs of about 40, the weather service said.
Temperatures that low will cause freezing in places like Lake Padden. But it’s not cold enough to make the lake a solid surface to safely walk or play on.
The National Weather Service has issued a wind advisory, warning that winds could gust up to 50 miles per hour today and tonight.
