Monday through Wednesday of this week we have had steady 20-30 mph winds and temps around zero, along with prodigious (feet) of lake effect snow. At 2 am Thursday morning, I awoke to the smell of smoke in the house, and it was pouring out of the back of the stove where fresh air was supposed to be going in! Stove temp was down quite a bit as well. I immediately suspected that the chimney was plugged. I shut the air inlet damper all the way shut and stuffed a towel into the air intake of the stove to try and stem the smoke spillage; then it started coming out the seam where the pipe connects to the ceiling box.
So, I get the extension ladder and get up on the roof at 2 am, it was 1/10 of a degree above zero, strong steady wind, and a raging snow squall in progress. The downwind side of the cap was completely iced up, and I am surmising that the orientation of the wind was just right such that the iced up 1/2 of the screen was "catching" and funneling the wind and not letting any of the wind to pass through the screen, or any of the smoke to escape. I took off the cap and the world was restored to its proper order.
It's a good thing I fell asleep on the couch that night and was able to catch it just when it started! Here are some snow pics for your review. The snow measured 37" high in the garage door opening, and it snowed another 8-10" Wednesday night.
