Even with the obvious building regs, would not be surprised to see some snow loads causing a few problems especially on flat roofs.
I live about 35 miles kinda north of Anchorage 11 miles north of Wasilla, I think the total snow from the last two weeks is about 2 feet on my house, I did go out and shovel off my old travel trailers cause they are flat and will sag badly, the snow is very light and crystal, in another two months if it snows it will get wetter and heavier. My roof isn't pitched very much but I do try to keep the snow to a minimum on the add-on rooms for the hot tub and my hobby room. I have not seen this much snow since around 1998 but it still pales in comparison to when I lived in the Sierra nevad at Lake Tahoe.As I came back from town yesterday there was the usual amount of ditchdivers and yes its treacerous driving up here, unlike living in Lake Tahoe where everybody uses tire chains nobody up here does on the main roads except some truckers, any smart person has two sets of mounted tires, one for good weather and another of snow/studded tire, I have both for my 4x4 dually which for the very first time I actually got stuck in a snowbank in my driveway yesterday!
Right now its -20F which is a little bit cold and I am on call from work building some models with my son and playing Xbox games waiting for winter to wane. He is playing Viva Pinato building his little garden, its a really nice game and much better than all the shooting games we usually play.
Global warming in Alaska? yes I would say our weather is warmer, last couple of winters were very short and warmer, summer was very dry too, this latest snowfall actually is normal by previous years depths. But a foot of this crystal light snow easily compresses down and is not hard to drive through also opposite the heavy wet glop I saw in Lake Tahoe that was like frozen quicksand. Worst danger here is driving after a plow truck that doesn't drop enough sand and scrapes the road down to polished white ice that is too slick to safely drive on, thats what causes a lot of accidents.
