Powered by NOAA / National Weather ServiceMariana Academy is a school in Apple Valley, California, part of Apple Valley Unified 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 Mariana Academy are almost always made at the district level. If Apple Valley Unified Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Apple Valley Unified 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.
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 Apple Valley Unified Schools before acting on it.
