My eyes have been so irritated these last 2 days. The smoke was even thicker today I think and we noticed ash (tiny white chunks) on our slanted skylight windows and deck rail today. It's never been this bad before which makes it a sad indicator of just how bad these blazes are.
When I checked Environment Canada website it's shown visibility in the past 24hrs in my area between 3km and 1.6km. Out of curiosity I picked a random day from 2 weeks ago that was sunny and visibility was 48km.

They are showing a 30% chance of rain tomorrow night and I hope like hell it does rain and rain good. Hopefully the rain will fall (no lightning please) and fall hard through Washington, Oregon and California as well to help extinguish these fires and clear the air.
