Because of winter weather, Princeton University will be closed for non-essential personnel on Monday, Jan. 26. Classes will be held at the discretion of the instructor. Instructors who need to alter class plans, including by holding class remotely, should communicate with students via Canvas. Instructors should consult this memo on holding classes during weather events. Only employees in essential services roles should report to work for shifts requiring them to work Monday, and they should park in either the Prospect Avenue, Theater Drive, or Stadium Drive garages. Do not park on the top level of any garage. Non-essential employees should not report to work. Employees should be prepared to perform work remotely if necessary for continuity of operations and to fulfill time-sensitive or otherwise necessary professional or departmental responsibilities. It is important to stay in touch with your manager. Here are additional updates: Check the TripShot app for updates on TigerTransit service. Recreational facilities will be closed. University libraries, including Firestone Library, will be closed. The Art Museum will be closed. Residential dining halls, including Procter Hall, are open as scheduled. All retail dining will be closed. See the FAQs for Severe Weather Delays and Closings for more information. Follow the guidelines on the EHS website for safety in winter weather. Members of the University community can manage how they receive non-emergency messages, including weather-related notifications, via the TigerAlert user portal. The University will provide an update on University operations by 3 p.m. Monday.

Message elements

How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

  • Sourceabsent0/25

    Final assessment

    source absent (25-pass consensus).

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardpresent25/25

    Final assessment

    hazard present (25-pass consensus).

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationabsent0/25

    Final assessment

    location absent (25-pass consensus).

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidancepresent25/25

    Final assessment

    guidance present (25-pass consensus).

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Timepresent25/25

    Final assessment

    time present (25-pass consensus).

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

  • Impactabsent0/25

    Final assessment

    impact absent (25-pass consensus).

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
