On a day when temperatures surged past 90 degrees in central New Jersey, an electrical problem has forced a school district to declare a snow day.

Classes were cancelled Tuesday in Keyport because of a malfunctioning component at the district's elementary school.

Officials cited student safety concerns for their decision, noting the building lacked reliable power. That meant students and staff members were facing a day with no phones, Internet or fire alarms.

Keyport Superintendent Lisa Savoia tells the Asbury Park Press (http://on.app.com/1XI1yfM) the district is logging the unexpected day off as a snow day, two of which are built into its school calendar.

The district's schools will reopen on Wednesday.
