Ottawa Local
Weather Forecast

Each future card shows precipitation chance and its expected point-in-time rate in mm/h. Fresh accepted local radar supplies the 1h and 3h rates and the first three hours of the cumulative total; the validated observation model supplies the nonnegative later tail. Rain arrival is the median first sustained 18-minute signal across the radar ensemble. The dashboard automatically returns to the current model when radar is stale, incomplete, rejected, or offline. The blowing wind face marks sustained winds of at least 35 km/h. Subtle ↑/↓ marks show meaningful changes from the previous complete run.
