It reads the National Weather Service forecast for Montville through the night and the 5 to 8 am bus run, adds winter alerts and the Winter Storm Severity Index, and measures the snow against Montville Township’s own big snow morning: 5 inches, the top tenth of snowy weekday mornings at a NOAA weather station 1.3 miles away.
New Jersey requires at least 180 days of school, or the district loses state aid.
A virtual or remote day counts toward the 180 days only when schools close for more than three consecutive days because of a declared state of emergency, a declared public health emergency or a health agency directive, under a program the commissioner approved.
