Almost every community in the state has been hit hard by smoke blowing in from British Columbia wildfires. You can see it, you can almost reach out and touch it, and many of us are feeling it.
If you look at air quality across the U.S., Washington has had the worst readings since the wildfire smoke hit the state earlier this week.

Monitors hitting high readings like never before
Mike Ragan, Ecology's air monitoring coordinator, took a snapshot of air pollution values across the state early Thursday and found high levels of particle pollution - everywhere."We've never seen numbers like this across the board," said Ragan. "When the state's cleanest air monitor hits very high levels of pollution, you know it's bad."

In the air pollution world, a daily average of up to 12 micrograms of particle pollution per cubic meter is considered in the healthy range. Anything over that has varying levels of health impacts:
- 0 – 12 Good
- 13 – 19 Moderate
- 20 – 34 Unhealthy for Sensitive Groups
- 35 – 80 Unhealthy
- 80 – 135 Very unhealthy
- Over 135 Severe impacts
"Last year at this time, Cheeka Peak read 1 microgram per meter. This morning, it had a reading of 208," Ragan said. "Cheeka Peek is near a shipping lane on the coast. That's not where we expect to see dense air pollution."
While the numbers Ragan captured were not the daily averages, they represent the bigger
picture: It's hard for people to breathe.
Below is the snapshot of readings Ragan took Thursday morning:

We saw it coming, but who knew it would be this bad?
Forecasters at Ecology tried to prepare people for the hit, issuing warnings beginning on Monday about the expected smoke, but they didn't know it would land this hard.
Brace yourselves, smoke is on its way. Winds are blowing smoke from BC wildfires into WA. See monitors & forecast: https://t.co/waREPrJ6y4 pic.twitter.com/CXFSzFyHeC— WA Dept of Ecology (@EcologyWA) July 31, 2017
"We knew a lot of smoke would transport from the B.C. fires, but this really is unprecedented," said Ranil Dhammapala, an Ecology atmospheric scientist.
If you can see it and feel it, don't go in it
So what can you do? You can always check state air quality monitors to determine what the air quality levels are, but a good rule of thumb is if you can see the smoke, stay inside. Health departments and toxicologists are urging people to forego strenuous outdoor activities. Now's not the time to get that really awesomely-hard park workout in or work on your best 10K time. Stay inside. Wait it out. Mow your lawn another day.By Camille St. Onge, Communications

In the 50 or so years I have lived in Western Washington, I have NEVER seen the air so bad. Someone has asked the question to me, which I hope gets answered: "Is there a point where the WA State Dept. of Ecology starts recommending evacuation?" (In other words, is there a number on the scale that would trigger such an event?
Please don't publish maps without a legend. I would really like to know what all the grey represents in the map at the top of the page. Would that be the smoke plume?

Here is another link to real time mapping. Under the Earth toggle at the bottom left there is a mode button that you can use to choose your poison.

We still love British Columbia.
