During severe weather, it’s important to be prepared for adverse conditions on streets, sidewalks and multiuse paths caused by snow and ice.

Extreme weather can sometimes lead to campus delays and closures. Campus officials are typically able to announce delays or closures by 5:30 a.m. Notifications of delays and closures are sent out via CU Boulder Alerts, campus social media channels and, often, local broadcast media. You can also view the university’s website for any change in operating status, as well as complete information on campus closing procedures.

Delayed opening

Sometimes, due to adverse conditions judged to be a hazard to normal campus operations, the campus will delay its opening.

For instance, if the campus were to have a delayed start at 9:45 a.m., this would mean all classes, recitations, labs, etc. scheduled to begin before 9:45 a.m. would be canceled. Faculty would take steps to make up material and assignments missed during that time in a later class period. All classes, labs, recitations, etc. scheduled to begin at or after 9:45 a.m. would be held as normal. Students with questions about making up assignments should talk to their faculty member.

How does a delayed opening apply during the fall 2021 semester?

  • Any in-person or remote (synchronously taught) class or lab scheduled to start at or after a delayed start time will meet as usual.
  • In-person and remote (synchronously taught) classes and labs that begin before the delayed start time are canceled, including those continuing past the late opening.
  • Online classes taught asynchronously, without a specific start time, are not affected by the delay.

Campus closure

In the event of a campus closure due to severe weather, all classes (in-person, remote and online) are canceled for the day.

Employee guidance

Administrative leave is granted to all regular employees for their scheduled work hours during the period of closure. Employees may reference the Inclement Weather Guidance from Human Resources for more information.

Resources and reminders

CU Boulder, the city of Boulder and the Colorado Department of Transportation offer several helpful resources and reminders for when the flakes start flying.

  • In the event of a campus closure or delay, the university will send a CU Alert message advising of campus operating status.
  • The Buff Info line will provide a recorded message for callers who are unsure about whether the campus is closed. Buff Info can be reached at 303-492-INFO (4636).
  • CU Boulder operations personnel from multiple departments work in concert with the city to remove snow from campus streets, parking lots, sidewalks and multiuse paths. It’s always important during storms to exercise caution when traversing campus, whether by foot, by bike or by vehicle. You are reminded to always wear appropriate footwear and to be careful getting in and out of vehicles, including buses.
  • Snowy weather can cause road closures and situations where campus officials must change bus routes to accommodate safe and accessible roads to and from campus. Riders should check the Transit app for campus bus updates and reroute alerts. Commuting students, faculty and staff riding to/from campus via RTD bus routes are encouraged to sign up for RTD Rider Alerts.
  • CU Boulder’s Division of Emergency Management features several weather safety tips on its website.
  • The city of Boulder’s snow and ice removal website features key things you can do to stay informed and be prepared for a snow event.
  • The Colorado Department of Transportation includes winter driving safety tips, reminders and road-condition updates on its website.
  • The latest Boulder weather forecast information can be found on the National Weather Service website.
