Good to know

  • Radar, lightning and airport reports are measurements. Temperature and wind are a forecast model’s values for the nearest hour, which can differ from what a thermometer in L'Assomption reads.
  • Past about zoom 7 for radar and zoom 8 for lightning the map shows no finer detail: it can’t resolve the weather of one street.
  • For a picture of conditions, not for safety decisions: follow the warnings of your local weather service.
