Mountain Winter Tips

Flagstaff snow comes deep and the sun is strong: big storms, sunny afternoons and cold nights. Here's what the city, ADOT and NOAA say about it.

Freeze-thawBig stormsSidewalk rules

Melt by Day, Ice by Night

Flagstaff's normal January high is 43.4°F and its normal low is 17.6°F (NOAA, 1991–2020). Snow that softens in the afternoon sun on walks, steps and steep drives can be solid ice by morning.

Clear Within 24 Hours

The city gives owners and occupants 24 hours after the accumulation to clear adjacent sidewalks. Clear all the way to the pavement so nothing is left to refreeze.

Mind the Shade

North-facing walks, shaded drive aprons and steps are where melt refreezes. Treat them before the evening cold sets in.

Keep Snow Off the Street

Flagstaff's ordinance prohibits moving snow or ice onto city streets or alleys. Pile it on your own property.

Move the Car

No parking on city streets or alleys from midnight to 7 a.m., November 1 to April 1, snowing or not.

Don’t Park on County Roads

Along county-maintained roads near Fort Valley and other snow-play spots, Coconino County bans parking Nov. 1 to Apr. 1: a citation of not less than $200 or a tow.

Plan Before November

Our analysis of NOAA daily records puts the median first measurable snow at the airport on November 10. Line up a crew and stock ice melt in October.

Big Storms and Heavy Roofs

January is the snowiest month at Flagstaff's airport (20.9 inches), followed by February (19.3) and December (18.5), and about 18.7 days a year bring an inch or more (NOAA). Deep, heavy snow is hard on backs, roofs, trees and snow blowers.

Push, Don’t Lift

A wide pusher or a two-stage blower moves deep snow without lifting it.

Watch the Roof Edge

Rake heavy snow off the roof edge from the ground. Stay clear of power lines and never work from a ladder; hire a pro for anything up top.

Plan for Outages

Run any generator outdoors only, far from windows, doors and garages, and keep snow away from the exhaust.

Driving in the High Country

Tires & Chains

ADOT says to use snow tires, chains or studded tires as recommended, required or both. Studded tires are permitted Oct. 1 to May 1.

Check AZ 511

Visit az511.gov, use the AZ511 app or dial 511 before you drive I-17, I-40 or the highways out of town.

Respect the Plow

Stay at least four car lengths behind snowplows and never pass one (ADOT).
