Powered by NOAA / National Weather ServiceSt John Catholic High School is a high school in Perth Road, Ontario, part of Catholic District School Board of Eastern Ontario. 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 St John Catholic High School are almost always made at the district level. If Catholic District School Board of Eastern Ontario closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Catholic District School Board of Eastern Ontario 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.
Ontario averages about 150 cm of snow per year. Ontario school boards make independent closure decisions. Northern boards have higher thresholds than southern Ontario. Toronto rarely closes, while Ottawa, Sudbury, and Thunder Bay close more frequently for heavy snow and extreme cold.
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 Catholic District School Board of Eastern Ontario before acting on it.
