With northern Arizona expected to receive upwards of 10 inches of snow above 5,000 feet starting Thursday and through the weekend, the Arizona Department of Public Safety (DPS) is asking motorists to slow down, drive cautiously and stay home if they can.
Overnight and morning low temperatures are expected to cause a hard freeze making highways extremely slippery.
If you must travel to the Flagstaff area beginning Friday, be patient as traffic will be moving slower, DPS said.
DPS is shifting resources to have as many officers available to respond to emergency calls.

• Leave at least 500 feet of distance between your vehicle and a snowplow or salt truck.
• Make sure your gas tank is full and you have food, warm blankets and clothing in the vehicle in case of emergency. If you have a cell phone, make sure it’s fully charged, working, and can be re-charged in your vehicle.
• Tell others about your travel route and itinerary.
• Keep others informed if you're going to be late or encounter problems so they won’t worry needlessly.
• It's safer to travel with passengers and convoy with other vehicles than it is to drive alone.
• Remember, the speed limit is based on clear roads and dry pavement, don't drive too fast for conditions. Four-wheel drive doesn't permit you to drive faster on snow packed or icy roads.
• Watch for slippery spots on bridges and overpasses.
• Take note of mileposts, exit numbers or crossroads in case you slide off the road or are involved in a crash so that law enforcement officers and tow truck operators can find you.
• If the storm makes driving too hazardous or if your car breaks down, stay in the vehicle. Run your engine and heater for short intervals to stay warm. Be sure to crack the window to avoid carbon monoxide build-up.
• Add a winter solution/ de-icer windshield washer fluid as summer solution will freeze solid.
