Inclement Weather

Inclement Weather Procedures

Because the University of Oregon (UO) is a residential campus with 24/7 operations, we rarely close.  In rare circumstances, however, hazardous weather conditions may force cancellation of classes and/or activities for part or all of a day. Closure decisions and procedures are managed in accordance with the university's Closure of Facilities and Operations policy.

Please review this information and make plans now, before the onset of inclement weather. In the case of inclement weather that disrupts UO operations, HR will also issue guidance specific to that situation as necessary.

Inclement Weather Notifications

UO will communicate information about delay, cancellation, or closure decisions for the Eugene campus as described on the Immediate Updates webpage

Official communication of any changes to the university’s schedule comes through UO Alerts texts and emails. Emails come to all “” accounts. To receive UO Alerts text messages in all emergencies, including weather situations, all employees and students should make sure current mobile numbers are activated. Manage UO Alerts at

Cancellation, delayed start, and early closure decisions

Weather-related schedule changes for the UO Eugene campus are made by senior leadership staff and Incident Management Team members, in consultation with local public safety, utility, and weather experts. Because weather conditions can rapidly change, and because schedule changes can be so disruptive to a complex academic and research institution, decisions are usually made each morning based on best available information and then communicated as soon as possible.

Cancellation, delayed start, and early closure decisions for UO campuses outside of Eugene are based on local conditions, with decisions made by designated sources:

  • UO Portland decisions are made at the discretion of UO Portland senior leadership.
  • Oregon Institute of Marine Biology in Charleston decisions are made at the discretion of OIMB senior leadership.
