  1. Initial Forecast

    Model forecasts 48% delay risk for San Diego departures 6–9 PM Saturday

    Tailodds’ model gives the 29 departures scheduled from San Diego 6–9 PM Saturday an average 48% chance of leaving 15+ minutes late. With calm weather the same flights would average 32%. From the 7:00 AM PST forecast (model famA-fc-v3+famB-sd-v4i). This is a forecast, not a report of delays.

  2. Escalation Forecast

    Updated model puts San Diego departure delay risk 6–9 PM Saturday at 63%

    What changed: 48% → 63% since the 7:00 AM PST forecast (model changed)

    Tailodds’ model gives the 29 departures scheduled from San Diego 6–9 PM Saturday an average 63% chance of leaving 15+ minutes late. With calm weather the same flights would average 32%. From the 9:00 AM PST forecast (model famB-sd-v4i). The model changed since the previous item (from famA-fc-v3+famB-sd-v4i), so some or all of this change comes from the new model rather than new information. This is a forecast, not a report of delays.
