Is the University Closed? Delayed? What to Know When Storms Strike

Nov. 28, 2023

Princeton University has procedures for when to delay opening or closing during severe weather. The University makes decisions based on the best available information.

A detailed FAQ is available to help you navigate the decision-making process around severe weather delays and closings, as well as get the most up-to-date information. 

The Weather Team communicates decisions about delays or closures in several ways – note that communications about morning decisions are posted or sent by 6:00 am:

  • InsidePrinceton – If there are any closures or delays, the campus status will be found at InsidePrinceton. Please note that closure information will no longer be posted on the University homepage.
  • TigerAlert – All faculty, staff, and students receive an e-mail and text message. Individuals may choose to receive a phone call by setting their preferences in TigerAlert via the portal. See TigerAlert User Portal Registration for instructions. 
  • TigerSafe app – Receive push messages on your mobile device. Download the TigerSafe app from the iOS or Android app store or go to the TigerSafe page for information. Anyone, including those without a campus NetID or affiliation, can download the app and receive messages.
  • SNOW line – As of winter 2023-2024, the 258-SNOW number will no longer be actively updated. Instead, individuals should look to get information on any weather-related closures via TigerAlert, InsidePrinceton, and/or the TigerSafe app.

If the University is open and operating, notifications will not be sent via these platforms.
