Flagstaff, Arizona, had the snowiest day in history

Flagstaff is buried in the snow: 35.9 inches. The city is under emergency and the flakes have not stopped.

The 2.9 feet that fell make Thursday the snowiest day in history, destroying the previous 31-inch record set in 1915.

The snowfall was only 2 inches less, making it the snowiest snowfall in Arizona's history. This record, set in 1968, is still at 38 inches.

It's so snow-covered that a photo, posted on social networks by Colonel Frank Milstead, director of the Arizona Department of Public Safety, shows the snow higher than the tires of an SUV of the state police.

The Arizona Department of Transportation urges everyone not to travel in or through northern Arizona. Road conditions remain too dangerous, with no timetable for improvement.

State soldiers say they have responded to more than 400 blocked vehicle calls and slips in 24 hours.

Meanwhile, snowbound Flagstaff locals like Chad Willimason are trying to dig with the help of snowblowers.

But Flagstaff is about to see even more snow on Friday – 3 to 5 inches more, if forecasts are good.

Spring is 26 days old.
