Powered by NOAA / National Weather ServiceCopper Basin is a school in San Tan Valley, Arizona, part of Florence Unified School District (4437). 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 Copper Basin are almost always made at the district level. If Florence Unified School District (4437) closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Florence Unified School District (4437) 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 Florence Unified School District (4437) before acting on it.
