Canadian Wildfire Smoke Expected Over Washington, Starting Friday

Smoke from wildfires in British Columbia is expected to drift overhead in Washington, but officials expect minimal air quality impacts.

While Western Washington has been blanketed by a marine layer in recent days, air quality experts believe wildfire smoke from British Columbia will join the overhead mix starting Friday.

SEATTLE — Air quality experts expect some wildfire smoke from British Columbia to be overhead in Washington as soon as Friday afternoon, but officials predict the plumes should stay high enough to avoid impacts for air on the ground.

The Puget Sound Clean Air Agency flagged the possibility of overhead smoke on Thursday, as dozens of wildfires burn across Western Canada amid a historic heat wave and tens of thousands of lightning strikes.

While the smoke will be visible up high, so far, experts expect air quality in the lowlands will remain in the "good" range through the holiday weekend. Impacts are expected to be a little more pronounced at higher elevations, with air quality potentially degrading to "moderate" in the Cascades.
