A powerful winter storm system struck Northern Arizona on Wednesday (February 18), bringing heavy snowfall, dangerous winds and challenging travel conditions across the High Country.
The National Weather Service (NWS) issued a Winter Storm Warning for the Mogollon Rim, Kaibab Plateau, and Flagstaff area beginning at 5 a.m., marking the second Pacific storm system in a series hitting the state expected to bring colder temperatures and lower snow levels than earlier in the week.
Flagstaff is expected to receive 4 to 8 inches of new snow throughout the day, while higher elevations will see significantly more accumulation.
Arizona Snowbowl is projected to gain an additional 12 to 16 inches, and other areas along the Mogollon Rim are bracing for substantial totals.
According to an article published by 12News, NWS in Flagstaff projected Forest Lakes to receive 6 to 8 inches, and Munds Park 4 to 6 inches. The heaviest snowfall intensity is expected between 5am and 9am before spreading eastward along the Rim.
Properties operating near Flagstaff, along the Mogollon Rim and the Kaibab Plateau should evaluate whether structures can handle heavy snow loads of this magnitude.
Glamping tents, yurts and cabin roofs require regular inspection and clearing during significant accumulation events. Heat-traced water lines and insulated utility pedestals help prevent freeze damage during the rapid temperature drops this storm system is producing.
Compounding the danger are powerful winds creating blizzard-like conditions across the region. The NWS has warned of widespread gusts across Northern Arizona, with localized gusts potentially reaching 65 mph in Snowflake, Springerville, and Winslow.
Pre-storm walkthroughs should also secure loose items, verify propane tank levels and confirm backup generators are operational before conditions deteriorate. RV parks should remind guests to disconnect water hoses and allow faucets to drip to prevent frozen pipes when temperatures drop significantly below freezing.
Establishing designated warming stations with emergency supplies including flashlights, blankets, water and first aid kits serves as a recognized safety measure for properties expecting to shelter guests through extended weather events.
The Flagstaff Unified School District canceled all classes for Wednesday, including food services and all before- and after-school activities.
Outdoor hospitality operators benefit from comprehensive staff training on winter emergency protocols during events of this severity. This includes understanding when to contact local emergency services versus handling situations internally, maintaining clear evacuation routes throughout properties and prioritizing snow removal on critical pathways.
Clear communication chains and defined responsibilities help ensure consistent response when conditions change rapidly.
