Due to the increased snowfall, the Coconino County Sheriff’s Office is warning backcountry mountain travelers to be alert for potential avalanche hazards on the San Francisco Peaks. The existing snowpack, wind and a large amount of new snow could produce hazardous conditions in the backcountry. This includes the side-country bordering the Arizona Snowbowl Ski Area.

Avalanche mitigation and patrolling is conducted within the Arizona Snowbowl, but there is no avalanche control or routine patrolling in the forest outside of the Snowbowl. Anyone traveling into the backcountry should be prepared for the current conditions. Avalanches most commonly occur during a storm or within 24 hours of the storm ending, though unstable conditions may continue beyond the initial time frame.

Backcountry users can obtain Snowpack Summary which outlines possible snowpack hazards from the Kachina Peaks Avalanche Center at www.kachinapeaks.org

  • I-40 eastbound was closed at SR 95 in northwestern Arizona, with traffic detoured south on State Route 95.

12 p.m. update:

As the snow continues to come down Thursday afternoon, meteorologists at the National Weather Service in Belmont are predicting the storm could surpass the record snowfall during a single calendar day in Flagstaff.

The record was set in December 1915 when the city received 31 inches of snow in a single day, said NWS meteorologist Jonathan Suk.

As of 11:49 a.m. the Flagstaff area had received 23.8 inches of snow with an additional 10 inches expected before midnight. The projected total would make for about 32 inches of snow fall in a single calendar day, surpassing that  all-time the record set over 100 years ago, Suk said.

The current 23.8-inch total also far surpasses the record snowfall for the calendar day of Feb. 21 by over 12 inches. The record snowfall for Feb. 21 was logged at 10 inches in the year 1944.

And Flagstaff is not alone Suk added. Prescott may also see record breaking snowfall for a single calendar day. That record was set in December 1967 when Prescott received 17 inches of snow. Suk said this storm is nearing that amount.

With the new expected total, Suk said the storm is bringing somewhat more snow than first predicted. Suk said this is partially because the storm is moving slower than NWS first believed, allowing more time for snow to fall over northern Arizona.

“This storm has been a real active changer,” Suk said, adding that this makes it more difficult to predict.

This also means the storm may start approaching the record amount of snow fall for Flagstaff in a two-day period, Suk said.

That record is 51 inches and Suk said they are expecting about 48.7 inches of snow by the end of the storm. Despite all the snow, Suk said residents shouldn't be too worried about the kind of flooding some parts on northern Arizona saw last week.

Thanks to the cold temperatures, Suk said, the snow will be able to settle and will begin to melt slowly. Flooding will only be a worry, Suk said, if the area experiences another warmer storm that brings rain.

“But we aren't seeing that one two punch,” Suk said.
