Powered by NOAA / National Weather ServiceDevelopmental Pre-School is a school in Mattawa, Washington, part of Wahluke School District. 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 Developmental Pre-School are almost always made at the district level. If Wahluke School District closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Wahluke School District 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.
Washington averages about 7 inches of snow per year. Seattle and Puget Sound districts close aggressively — even 1-2 inches causes widespread closures due to steep hills and limited salt reserves.
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 Wahluke School District before acting on it.
