Synopsis
This sort of weather's uncomfortable for us humans, but it would have to get much, much worse to bother the bears. They can handle extreme blizzards and temperatures down to about minus 40 with no problems. They'll scoop out a shallow shelter, hunker down and let the bad weather blow itself out.
