Cal State Long Beach officials canceled in-person classes on Tuesday evening because of a power outage on campus.

Online classes were still scheduled to take place. 

It’s not clear what caused the outage but officials asked that “unless you live in the residence halls, please leave campus for your safety.”

Power was restored by about 7 p.m., according to the university police department. Classes were scheduled to resume in the morning.
