Northern Arizona University closed its Flagstaff Mountain Campus on Friday, March 14, 2025 as a significant late-season winter storm moved through northern Arizona. The closure decision, pushed through the NAU Safe notification system and campuswide email, cited a National Weather Service winter weather advisory running 3 p.m. Friday through 5 a.m. Saturday and 4-6 inches of additional snow forecast for Flagstaff at roughly 7,000 feet elevation.

NAU Safe: Due to winter weather, the Flagstaff Mountain Campus is closed today, Friday, March 14. The National Weather Service has issued a winter weather advisory and travel is discouraged. Please take care when traversing campus as facilities crews work to clear snow.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed from coverage describing the closure announcement, which cited the NWS advisory and asked the community to 'take care' while crews cleared snow.
NAU states closure decisions are made by 6:30 a.m. Arizona time, so this notification timing matches the university's documented procedure.
Arizona does not observe daylight saving time, so the timezone is MST (UTC-7) year-round even in March; only the Navajo Nation in northeastern Arizona observes DST.
isVerbatimConfirmed:false: NAU's archived NAU Safe message text could not be retrieved, so the wording paraphrases the documented announcement.
Context

Background

Flagstaff sits at about 7,000 feet and is one of the snowiest cities in the United States, which makes Northern Arizona University's Mountain Campus an unusual case among Sun Belt institutions: its weather-closure playbook resembles a New England school more than a desert one. On Friday, March 14, 2025, NAU closed the Flagstaff Mountain Campus as a late-season storm rolled in. The university routes closure decisions through a campuswide email and the NAU Safe notification system, and its Office of Emergency Management alerts page carries the live status. The closure was tied to a National Weather Service winter weather advisory in effect from 3 p.m. Friday through 5 a.m. Saturday, with 4-6 inches of additional snow forecast. NAU documents that closure or delay calls are finalized by 6:30 a.m. Arizona time, and the NAU Review's snow guidance explains the multichannel notification process. Because Arizona does not observe daylight saving time, NAU's Flagstaff campus runs on MST year-round.
Analysis

Key Findings

NAU's Flagstaff Mountain Campus operates a true winter-weather closure protocol despite being a Sun Belt university, because of its 7,000-foot elevation
The closure was a discretionary advisory, not a Clery emergency notification, because it managed predictable severe weather rather than an immediate threat
NAU finalizes closure or delay decisions by 6:30 a.m. Arizona time and pushes them through NAU Safe plus campuswide email
Arizona's no-DST rule means the campus runs on MST year-round; the Navajo Nation in the state's northeast is the lone DST-observing exception
Outcome
The Flagstaff Mountain Campus closed for the day. NAU asked the community to take care while crews cleared snow. Statewide campuses at lower elevations operated normally.
