Powered by NOAA / National Weather ServiceGrand Trunk High School is a high school in Evansburg, Alberta, part of The Grande Yellowhead School Division. 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 Grand Trunk High School are almost always made at the district level. If The Grande Yellowhead School Division closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the The Grande Yellowhead School Division 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.
Alberta averages about 130 cm of snow per year. Alberta school boards rarely close for snow alone. Extreme cold warnings below -40°C with wind chill and Chinook-related ice storms are the primary triggers. Calgary boards may close differently from Edmonton boards due to Chinook effects.
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 The Grande Yellowhead School Division before acting on it.
