OMAHA, Neb. (AP) — Classes and other operations are expected to resume Wednesday at Creighton University in Omaha, where a power outage emptied two dorms and forced some class cancellations.

Creighton spokeswoman Cindy Workman says power was restored overnight to all buildings affected by Tuesday’s outage, which started around 10 a.m.

Cots were set up in the university’s Sokol Arena for the 675 students displaced from the two freshman dorms. Students from the Omaha area were asked to just go home for the night.

University officials blamed two failed circuits for the outage.
