Residents in King and Snohomish counties are advised to be cautious as an Air Quality Alert for Smoke is in effect until noon PDT Wednesday, as per the Puget Sound Clean Air Agency. The alert underscores that air quality is currently ranging from 'unhealthy for sensitive groups' to 'unhealthy' primarily in south and east Snohomish County and in regions of north and east King County, due to smoke from nearby wildfires.

As conditions continue to change, those with respiratory issues or other health concerns should take special notice. The forecast suggests that the air quality may remain moderate in Pierce and Kitsap Counties. However, the smoke is affecting larger areas and is expected to persist over the next day. Residents should anticipate this and plan accordingly, limiting their outdoor activities as much as possible to minimize exposure. According to the alert, "Smoke impacts may occur across King and Snohomish Counties over the next day."

Looking ahead, relief might be in sight for those under the blanket of smoke. The aforementioned alert forecasts that westerly winds should make a return by Wednesday evening, which could help in dissipating the smoke. To stay abreast of updates and for additional resources on maintaining cleaner indoor air, the public can visit the Puget Sound Clean Air Agency website at pscleanair.gov.

While the Air Quality Alert is a concern, the National Weather Service provides a glimpse of what else to expect weather-wise in Seattle. The city can look forward to sunny skies with a high near 71 degrees today, along with a calm north wind. For the nocturnal hours, they predict mostly clear conditions with lows around 51. Thursday should be partly sunny with calm winds, while the weekend's forecast hints at a 20 percent chance of rain Saturday and likely rain beginning Sunday night into the following week.
