UPDATED: Wildfire smoke expected to linger longer

FERNDALE, Wash. — Washington State Department of Ecology officials said this morning, Monday, September 14th, they were disappointed not to be “seeing substantial improvements along the coast this morning” as some weather forecasts had predicted.

To add to our woes, light southerly winds will continue for another day at least, dragging more smoke directly from Oregon fires northward along the I-5 corridor. So even if the ubiquitous smoke pool from offshore starts to erode a bit, a replacement is en route.

Ecology’s smoke forecast for western Whatcom County and the Ferndale area is for air quality to improve today from “UNHEALTHY” to “UNHEALTHY FOR SENSITIVE GROUPS” and then to improve again tomorrow to the “MODERATE” zone.

Air quality in the Ferndale area has cycled between “VERY UNHEALTHY” and “UNHEALTHY” for the past 3 days as winds from the south pulled smoke from southwest Washington, Oregon and California wildfires into the Puget Sound region.

Forecasters with the National Weather Service office in Seattle said early this morning smoke will possibly remain an issue further into the week. There is a possibility for a frontal system to bring some spotty showers later today through Wednesday to some parts of western Washington and an upper low will slowly move onshore later in the week bringing light winds.
