Campus Alerts - Carnegie Mellon University

In Severe Weather, Check TV, Web and CMU Alert

In the event of severe weather, members of the campus community should tune in to KDKA-TV, WTAE-TV or WPXI-TV for official university announcements regarding delays, cancellation of classes and/or office closings. Announcements also will also be posted on this website and recorded on the Carnegie Mellon main switchboard (412-268-2000). Notification may also be sent via the CMU Alert Emergency Notification Service.

Unless otherwise noted, the cancellation of classes will include evening classes at the Heinz College and the Tepper School of Business. Unless an official notification is issued, the university will maintain normal operations.

While Carnegie Mellon may cancel classes or close offices due to severe weather, the university cannot close operations because it provides residential space and services for thousands of students on campus. Therefore, essential employees from several departments, including Facilities Management Services, University Police, Housing and Dining Services and Computing Services, may be required to report for work.

Supervisors should identify and brief essential personnel regarding their responsibilities during severe weather.
