Wildfire smoke in western WA

Smoke from the eastern Washington wildfires will continue to stream in as offshore flow continues into Tuesday.  Tuesday morning will be hazy, especially in the north sound as the smoke rolls over the cascades due to the easterly flow. An onshore push by Tuesday will help to clear the air starting along the coast and will continue to improve the week for western Washington.
