First Smoke of the Season

I was a bit surprised when I saw the visible satellite imagery this morning:  there was clearly significant wildfire smoke over the eastern portion of Washington State (see image below).  This smoke is aloft and not reaching the surface.

This is confirmed by air quality monitors around the region, which are all green (good air quality).

The Cherrywood fire is now about 15,000 acres in size and is burning in mainly grass, so I suspect it will be short-lived (grass fires generally burn fast and are accessible to fire-fighting).  

You can see the movement of the smoke from the simulation of the NOAA HRRR-Fire system.  Here is the predicted smoke at 11 AM.  You can see the smoke's origin and its movement northward.

And the 6 AM forecast is nearly perfect, with the dense smoke over eastern Washington. 

The smoke should spread out (diffuse) and move westward over time but will remain aloft.

  1. Time to stock up on filters for my air filtering machine…

    1. Yes we bought the last few furnace filters (recommended for smoke) from a local store. And last year we invested in air conditioning. I would otherwise wake up choking and coughing during the BC/Kitsap county fires with my windows open at night. It was really awful about 2 years ago. Smoke came from every direction. I mentioned the air conditioning to my neighbor and she just rolled her eyes. I am not sure how she deals with summer heat and summer smoke at the same time. What do people do?
