Ross Hall was evacuated just after 12 p.m. Monday and will be closed for the rest of the day, after flooding at the Washington Harbour affected three Pepco power feeders, triggering a power outage in the building.

Classes in the building this evening are canceled, and the Himmelfarb Library is also closed, according to a Campus Advisory.

University spokeswoman Michelle Sherrard said the building was still without power at 1:20 p.m., adding that Pepco does not know when power will return.
