Powered by NOAA / National Weather ServiceHidden Valley High School is a high school in Grants Pass, Oregon, part of Three Rivers/Josephine County SD 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 Hidden Valley High School are almost always made at the district level. If Three Rivers/Josephine County SD Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Three Rivers/Josephine County SD Schools forecast).
Rural districts run the longest bus routes over the least-treated roads, so they typically close at lower snowfall totals than nearby urban districts — often on forecasts that would leave a city district open.
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.
Oregon averages about 5 inches of snow per year. Portland and the Willamette Valley close at very low thresholds — any snow or ice accumulation on roads typically triggers closures.
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 Three Rivers/Josephine County SD Schools before acting on it.
