Students at Boiling Springs High School were dismissed at 10:15 a.m. after a power surge and partial power outage, according to South Middleton School District.

Only the high school was affected.

In an email to parents, acting superintendent Bruce Deveney said the partial outage affected some "significant mechanical systems" in the building and necessitated the closing of the high school for the remainder of the day.

As of Monday morning, it was unknown if the outage would also affect classes Tuesday.
