  "context": "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](https://azdailysun.com/news/local/education/nau-closes-flagstaff-campus-due-to-winter-weather/article_4f5fce6e-00ef-11f0-b2ec-933c576af179.html) as a late-season storm rolled in. The university routes closure decisions through a campuswide email and the [NAU Safe notification system](https://in.nau.edu/its/nausafe/), and its [Office of Emergency Management alerts page](https://in.nau.edu/emergency-management/alert/) 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](https://news.nau.edu/stay-in-the-know-for-snow) explains the multichannel notification process. Because Arizona does not observe daylight saving time, NAU's Flagstaff campus runs on MST year-round.",
  "keyFindings": [
    "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"
