Closure decisions for Northern Valley Regional High School at Old Tappan are almost always made at the district level. If Northern Valley Regional High School District closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Northern Valley Regional High School District forecast).
Suburban districts depend heavily on bus fleets covering a wide area of residential streets, which are plowed after main roads. Side-street conditions at 5 AM often decide the call.
High schools start earliest, so they feel a storm before the rest of the district does — the first buses often roll while roads are still being treated. That earlier start time is one reason a district watching a morning storm may call the day off entirely rather than run a delay.
New Jersey averages about 25 inches of snow per year. New Jersey districts are notorious for preemptive closures. Northern NJ closes more frequently than southern counties.
We score the live forecast at this location against the factors that drive closure calls: snowfall total and intensity, when the heaviest accumulation lands relative to the morning commute, ice and freezing rain, wind chill, and how confident the forecast models are. You get a probability for a full closure, a two-hour delay, and an early dismissal.
