If you went outside today and noticed it smelled like smoke, you weren't alone.
Smoke from six large wildfires burning in Southern California is drifting into the Pacific Northwest, where the air quality is already degraded and the Puget Sound region is under an Air Stagnation Advisory.
>> Air Stagnation Advisory extended until Thursday
A high pressure system remains over Western Washington, causing cold and calm weather conditions and preventing wind from blowing away air pollution.
The first image from NASA shows the smoke moving up from the south into Washington state on Monday.

The second NASA image, taken on Dec. 8, shows the massive smoke plume coming from California. At that time, the smoke was blowing offshore away from us, but that has since changed.
The third photo, is from a Dec. 8 International Space Station flyover of Southern California. NASA astronaut Randy Bresnik photographed the plumes of smoke rising from wildfires.
>> How does ozone relate to air pollution and how bad is our air?
Bresnik wrote on Twitter, "From @Space_Station it looks like the winds have shifted and hopefully dying down, nice to see Point Mugu and Oxnard again, hopefully Ventura soon."
