Powered by NOAA / National Weather ServiceDavid Douglas High School is a high school in Portland, Oregon, part of David Douglas SD 40 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 David Douglas High School are almost always made at the district level. If David Douglas SD 40 Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the David Douglas SD 40 Schools forecast).
Urban districts usually have the best-treated roads and the shortest bus routes, so they tend to hold out longer before closing — but they also weigh sidewalk conditions and transit reliability for students who walk or ride public transport.
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.
