Latest winter storm brings rain, snow to Arizona; most highways reopened

The latest winter storm dumped rain and snow across Arizona, and the weather shut down major highways in the state.

In the Valley, rain began to fall overnight and into Wednesday morning. Lingering showers remained for the rest of the day and into Thursday. There's a slim chance for more rain on Friday.

"The unsettled weather will continue over the next few days with scattered showers & a few isolated t-storms today followed by more widespread light rainfall mainly Thursday afternoon," the National Weather Service Phoenix wrote in a post on X.

Up north in Flagstaff, heavy snow continued to fall on Wednesday and Thursday, closing major highways and shutting down schools.

"With numerous road closures and widespread snowfall for much of northern AZ, travel will be dangerous to impossible this AM," the National Weather Service Flagstaff wrote on X. "Travel conditions remain poor the next several days before much improved conditions arrive Sunday."

The latest highway closures, according to the Arizona Department of Transportation:

  • State Route 64 east of the Grand Canyon National Park (mileposts 242-276)

"Interstate travelers looking to pass through Arizona are encouraged to use southern routes, including I-10 and I-8, for travel," officials wrote on

Leave prepared before heading north

After recent snowfall in the high country, the Arizona Department of Transportation is reminding drivers who are heading north to never park along highways to play in the snow. 

Use the highway shoulders for emergencies only. Parking on them to play in the snow is hazardous in the following ways:

  • Other drivers may be distracted by your vehicle.
  • Other drivers may pull over as well to play in the snow, compounding the problem.
  • Your vehicle may interfere with first responders who need to use the shoulder.
  • Plows can throw snow and ice far off highways.
  • It’s much safer to re-enter highways from on-ramps and other designated entrances

"Also, it’s not uncommon for lots of desert dwellers to take the opportunity to head north to play in the snow. So, remember to pack your patience and expect to spend extended time in your vehicle getting to and from snow play areas."

ADOT's suggestions for items to take along:

  • Warm clothing and blankets
  • A fully charged mobile phone and charger
  • Flashlight with extra batteries
  • Drinking water
  • Healthy snacks
  • First-aid kit and necessary medications
  • Ice scraper
  • Small bag of sand or kitty litter for wheel traction
  • Small folding shovel for snow removal
  • Travel tool kit and battery cables
  • Safety flares
  • Plastic bags or containers for sanitation
  • Road map(s)

ADOT says you and your vehicle must be prepared for driving in wintry conditions, including snow, ice and freezing temperatures.

  • Get plenty of rest
  • Plan your route in advance and notify someone about your route, destination and arrival time
  • Take frequent breaks from driving
  • Make sure your fuel tank is at least half to three-quarters full at all times
  • Use snow tires, chains or studded tires as recommended or required. Studded tires are permitted on Arizona highways from Oct. 1 to May 1.
  • Ensure your wipers, window defroster, headlights, taillights, brake lights and turn signals work
  • Change your motor oil to a winter grade
  • For electric or hybrid vehicles, be sure the battery has sufficient voltage and the connection cables are tight
