NAU Safe: A Bomb Threat has been reported in the area of Ardrey Auditorium. Evacuate the area immediately. More information will follow.

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

Reconstructed from KNAU and FOX 10 reporting, which quote the NAU Safe alert as stating a bomb threat had been reported in the area of Ardrey Auditorium and advising those nearby to evacuate immediately; the closing sentence is reconstructed and the message is not confirmed verbatim.
Arizona does not observe daylight saving time, so the timezone offset is -07:00 (MST) year-round — a common mistake for out-of-state readers.
The alert named a single building rather than imposing a campuswide shelter, reflecting a contained evacuate-the-area response to an unconfirmed phoned threat during finals week.

Reconstructed from the Arizona Daily Sun and azfamily reporting that the area around Ardrey Auditorium was declared safe at 4:01 p.m. MST after a sweep found no hazardous devices or materials; the all-clear language is reconstructed, not confirmed verbatim.
An earlier preliminary search around 2:30 p.m. MST had already indicated no imminent threat before the formal all-clear nearly 90 minutes later.
Context

Background

Ardrey Auditorium is NAU's main performing-arts hall on Knoles Drive in Flagstaff, a venue that hosts commencement-season concerts and recitals. On the afternoon of May 14, 2026, a phoned-in bomb threat prompted NAU to push a NAU Safe alert shortly after 1 p.m. MST telling people to evacuate the area. NAU Police were joined by the Flagstaff Police Department, who searched the auditorium and interviewed potential witnesses. A preliminary search around 2:30 p.m. found no imminent threat, and the area was declared safe at 4:01 p.m. MST. The incident fit a national pattern of phoned and emailed bomb threats targeting individual campus buildings during spring 2026, almost all of which proved unfounded after a sweep.
Analysis

Key Findings

NAU used a single-building 'evacuate the area' response rather than a campuswide shelter-in-place, reflecting a contained reaction to an unconfirmed threat
The all-clear at 4:01 p.m. MST came roughly three hours after the initial alert, despite a preliminary search clearing the building by about 2:30 p.m.
Arizona's lack of DST means the correct offset is MST (-07:00) year-round, not MDT
The threat targeted a performing-arts venue during commencement season, when such buildings see heavy public traffic
Outcome
A thorough sweep of the auditorium found no hazardous devices or materials. The area around Ardrey Auditorium was declared safe at 4:01 p.m. MST and NAU operations returned to normal.
