A significant winter storm recently blanketed northern Arizona with heavy snowfall, leading to extensive traffic disruptions, particularly along Interstate 40 (I-40).
The storm, described as the most substantial of the winter season, brought much-needed precipitation to the region but also posed challenges for travelers and residents alike.
Impact on Interstate 40
On Friday, March 7, 2025, westbound I-40 between Flagstaff and Williams experienced a traffic standstill extending over 15 miles (24 kilometers). The combination of heavy snowfall and a two-vehicle collision contributed to the prolonged congestion.
Arizona Department of Public Safety spokesperson Bart Graves noted that adverse snow conditions hindered prompt clearance efforts, resulting in hours-long delays. While injuries were reported from the crash, no fatalities occurred in the region due to the storm.
Additional Road Closures
The storm’s severity prompted the Arizona Department of Transportation (ADOT) to implement several road closures to ensure public safety. Notable closures included:
- Interstate 17 (I-17): Initially closed between State Route 169 and the I-40 interchange (mileposts 299-340), it was later reopened on Friday afternoon.
- State Route 89A: Closed due to hazardous conditions.
- State Route 87: Closed south of Payson at milepost 238.
ADOT advised motorists to delay travel plans until the storm subsided and road conditions improved.
Snowfall Accumulation
The storm delivered varying snowfall amounts across northern Arizona:
| Location | Snowfall Amount |
|---|---|
| Flagstaff | Over 1 foot (30 centimeters) |
| Munds Park | Over 1 foot (30 centimeters) |
| Williams | Over 2 feet (60 centimeters) |
Lower elevations received a few inches of snow, while higher elevations experienced more substantial accumulations.
Community Response and Safety Measures
During the traffic standstill on I-40, drivers exhibited patience and adaptability. Some individuals exited their vehicles to engage in activities like snowball fights, while others assisted fellow motorists by using tow straps to pull vehicles out of deep snow.
ADOT deployed snowplows to affected areas and advised drivers to maintain a safe distance of four car lengths behind the plows. Motorists were also encouraged to equip their vehicles with snow tires or chains and carry essentials such as water, blankets, and fully charged phones when traveling in winter conditions.
The recent winter storm in northern Arizona underscored the region’s vulnerability to severe weather events and the importance of preparedness.
While the heavy snowfall brought challenges, it also replenished much-needed moisture to the area. Residents and travelers are reminded to stay informed about weather conditions and adhere to safety guidelines during such events.
