Thunderstorms knocked down a utility pole Thursday afternoon around Chatham and Woodland roads causing power outages in the area.
Residents in the area could experience rolling power outages as JCP&L repairs the downlines. Power is expected to return by the morning.
However, in an email to parents Superintendent Dr. James Crisfield said Glenwood School will be open for a full day with or without power Friday.
"We have had plenty of practice with such scenarios in recent years, so in a strange sense, practice makes perfect," he said. "Crews will be working through the night, but it is possible that power will not be fully restored until later in the day Friday. In fact, what remains of electricity service in the affected area may have to be purposely cut for a short while during the repairs."
The work that needs to be done to replace the pole and reattach wires will require intention outages by the power company in and around Chatham Road and the Short Hills Train Station, according to the website.
The school has water service and Crisfield said, the school has sufficient natural light in most classrooms.
"The building will be dark in certain parts [but] Dr. Jasin has a good plan to avoid those sections of the building as need be," Crisfield said.
Chatham Road will be closed between Baltusrol Avenue and Woodland Road for the duration of the repairs. Cars parked in the commuter parking lots will be able to exit and leave traveling to Baltusrol and Short Hills Avenue.
The number of homes that will be affect is unknown.
Crisfield added, "It wouldn't be a new school year without a weather challenge. So if called upon, we're up to it, once again.
