Omaha Public Schools will remain closed indefinitely to help limit the spread of the new coronavirus, officials announced Monday evening.

The Omaha district had earlier announced plans for temporary closures that would extend spring breaks to about two weeks, but officials now say there is no tentative date to resume classes. District administrators said they will evaluate health conditions every two weeks and consult with local and state officials as they determine when to reopen.

The move followed Nebraska Commissioner of Education Matt Blomstedt’s request that school officials across Nebraska make plans for school closures.
