Why Do We Cancel A Session?
Once windchill becomes colder than -27 degrees Celsius, frostnip on the face goes from linear to exponential risk. See “Guidelines on the Risk and Time to Frostbite during Exposure to Cold Winds” for details.
Assiniboine Park Jackrabbit coaches will run or cancel a Jackrabbit session based on what Environment Canada Weather is currently observing and roughly predicting for Winnipeg at the Winnipeg Richardson International Airport.
The coaches use Spot WX graphical repackaging of Environment Canada weather data and forecasts for Winnipeg to make our final call to run or cancel a session.
