Powered by NOAA / National Weather ServiceMiramonte High is a high school in Orinda, California, part of Acalanes Union High Schools. The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.
Closure decisions for Miramonte High are almost always made at the district level. If Acalanes Union High Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Acalanes Union High Schools 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.
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.
This is an independent forecast, not an official announcement. Confirm any closure with Acalanes Union High Schools before acting on it.
