A powerful winter storm swept through northern Arizona early Thursday morning, blanketing the Grand Canyon region with record-breaking snowfall that has disrupted travel, closed key roadways, and prompted emergency declarations across Coconino County. The National Weather Service confirmed that some areas received upwards of 18 inches of snow in a 24-hour period, making it one of the most significant winter weather events the region has experienced in over a decade.
The storm, which meteorologists had been tracking since early in the week, intensified rapidly as it moved across the Colorado Plateau. Winds gusting up to 55 miles per hour combined with heavy snowfall to create near-whiteout conditions along Interstate 40 and State Route 64, the primary access road to the Grand Canyon South Rim. Arizona Department of Transportation officials announced closures on multiple roadways by 6 a.m., urging motorists to avoid non-essential travel throughout the region.
Grand Canyon National Park officials confirmed that both the South Rim and North Rim entrances were temporarily closed to vehicle traffic. Park spokesperson Linda Hernandez stated that ranger crews were working around the clock to assess conditions. “The safety of our visitors and staff is our top priority,” Hernandez said during a midday press briefing. “We are coordinating with ADOT and county emergency services to restore access as quickly as possible, but we urge everyone to stay off the roads until conditions improve.”
In Tusayan, the gateway community to the Grand Canyon’s South Rim, local businesses reported significant impacts from the storm. The small town, which relies heavily on tourist traffic, saw a near-complete halt in visitor arrivals. Hotel operators scrambled to accommodate stranded travelers while restaurants and shops opened with skeleton crews. Tusayan Fire Chief Marcus Delgado confirmed that emergency responders had assisted several motorists who became stuck on Highway 64 overnight.
Flagstaff, located approximately 80 miles southeast of the Grand Canyon, also bore the brunt of the storm. The city declared a snow emergency, activating plowing operations on all priority routes. Northern Arizona University canceled classes for the day, and Flagstaff Unified School District announced closures across all campuses. Flagstaff Pulliam Airport reported multiple flight cancellations and delays throughout the morning.
Williams, another key gateway town along Interstate 40, experienced similar disruptions. The historic downtown area was blanketed in heavy snow, and the Grand Canyon Railway announced the suspension of its daily train service to the South Rim. City Manager Robert Trujillo urged residents to check on elderly neighbors and ensure they had adequate heating supplies. “Our public works teams are doing an incredible job, but this is an extraordinary amount of snow,” Trujillo told The Grand Canyon Gazette.
The Coconino County Emergency Management office activated its emergency operations center Wednesday evening as the storm approached. County officials coordinated with the American Red Cross to open warming shelters in Flagstaff and Williams for anyone displaced or without adequate heating. County Manager April Rhodes emphasized the importance of community preparedness during winter storm events in the high desert region.
Local schools across the region announced extended closures through Friday, giving road crews additional time to clear secondary routes used by school buses. Superintendent Dr. Angela Vasquez of Grand Canyon Unified School District said the safety of students and staff could not be compromised while road conditions remained treacherous. Parents were encouraged to check the district’s website and social media channels for updates on when classes would resume.
Meteorologists expect the storm system to move east by Friday morning, with clearing skies anticipated by the afternoon. However, temperatures are forecast to plummet into the single digits overnight, raising concerns about ice formation on roads and walkways. The National Weather Service has issued a hard freeze warning for the entire region through Saturday morning. Residents and visitors are advised to monitor local weather updates and follow guidance from emergency management officials as recovery operations continue throughout the weekend. Power outages were also reported in scattered areas around Williams and Tusayan, with Arizona Public Service dispatching additional repair crews to restore service as quickly as conditions allow.
