I lost power for 7 days in 2011, it sucked, lucky I had a wood stove, but you can't shower, it's a pain to cook anything even though my stove has a cook top and I couldn't work and make any money.
I checked a few sites and they were all in that range, I was up there for a bowling tournament in November and talking to the locals they said they don't get a lot of snow but not too far in the mountains gets a lot more.
