Smoke is very heavy from about Red Bluff or Redding all the way to Vancouver Canada now and then all the way across the U.S. and Canada to the East Coast

 Yesterday the smoke was only from about Red Bluff to Eugene Oregon but obviously a lot changed because when I checked just now I realized that it's now from Red Bluff and Redding all the way to vancouver, Canada. And then from there all the way through Canada and northern U.S. to the East coast of Both Canada and the U.S.
