Powered by NOAA / National Weather ServicePolyvalente Sainte-Thérèse is a high school in Sainte-Thérèse, Quebec, part of Centre de services scolaire des Mille-Îles. 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 Polyvalente Sainte-Thérèse are almost always made at the district level. If Centre de services scolaire des Mille-Îles closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Centre de services scolaire des Mille-Îles forecast).
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.
Quebec averages about 210 cm of snow per year. Quebec school service centres (CSS) make regional closure decisions. Montreal closes less often than Quebec City and eastern Quebec, where heavier snowfall and ice storms are more common.
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 Centre de services scolaire des Mille-Îles before acting on it.
