Q: How does the Hollis-Brookline Cooperative snow day predictor work?

It reads the National Weather Service forecast for Hollis 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 Hollis-Brookline Cooperative’s own big snow morning: 6.5 inches, the top tenth of snowy weekday mornings at a NOAA weather station 5.6 miles away.

Q: Can New Hampshire schools hold a remote day instead?

Remote learning counts toward the required instructional time when bad weather makes it unsafe to transport students, with no cap stated in the rule.
