A relentless winter storm pounded the West for a fourth consecutive day Thursday, from the Rockies to the Dakotas and in areas already buried under as much as five feet of snow.
New snow up to a foot deep was a possibility for Arizona's White Mountains, where 42 inches already had fallen. The slow-moving storm has dumped between two and five feet of snow in the mountains of central Arizona, the National Weather Service said.
Snow and freezing rain continued to fall Thursday, from the Dakotas to the southern Rockies and across the Southwest.
The Purgatory Ski Area in southwest Colorado reported 21 inches of new snow, and accumulation of 48 inches within 48 hours. Nearby at Durango, La Plata County Airport was closed Wednesday night, after an American Airlines jet skidded off an icy runway into a snowbank. No injuries were reported.
"Most people around here have four-wheel drive or chains," a central police dispatcher in Durango said. "Everything's pretty much open and active; it's just slow because of the weather."
