Last week we got 22 cm of snow (an inch is about 2.45 cm, so about 11 inches). This weekend we're going to get another 15 cm (about 7 inches) or more. I ended up actually asking my brrother the civil engineer whether there was any danger of roofs collapsing from the weight of all that snow, and he said not around here. But if next weekend we get another foot of snow when we could end up with fire trucks having trouble reaching the sites of fires.
