We are having sustained winds of 45mph with gusts to 65mph.
I have had a large wad of newspaper in my prefab chimney that goes straight up through the ceiling and out of the roof. It has been there all summer and it just got sucked up to the top of the chimney. It makes a good case for a baro damper to be used when the stove is running. With suction like that it may have sucked the coal right off of the grate.
