Climatologist Rick Thoman says climate change is driving this more extreme winter snowfall. As the oceans warm, more moisture evaporates into the air. Then, when the atmospheric conditions are right for a storm, that increased evaporation results in “heavier and heavier precipitation,” Thoman said. That’s in part why Anchorage saw 41.2 inches of snow last month, capping off its wettest year on record, according to the National Weather Service.

Anchorage and Mat-Su Borough schools and state offices are closed Thursday as a third major winter storm this month coated the area with snow overnight Wednesday. “In the past 11 days, we’ve had 41.1 inches of snow which is a lot for Anchorage,” Baines said.

All schools in Anchorage and the Mat-Su Borough are closed Wednesday due to slick roads across the region, as snowfall continues. “This is the heaviest snowfall the Anchorage area has seen in over 20 years,” said state Department of Transportation spokesman Justin Shelby. “Our crews are keeping up as best they can.”
