SPECIFIC SITE NOTES:

GENERAL NOTES:
  - Days 1-10 are from the CBRFC deterministic model. This uses
    5 days of precipitation forecasts and 10 days of temperature
    forecasts. These are updated daily and will change as the
    weather forecast changes, so there is increasing uncertainty
    past days 3-5.
  - Days 11 and beyond are from the Ensemble Prediction Model (ESP).
    This model is driven primarily by climatology for the 1981-2015
    period. This guidance is probabilistic and used the 50% exceedance
    value. It is best to use this as a possible pattern of flow into
    the future as opposed to an exact value that will occur.
  - An abrupt change in guidance may occur at the switch from the
    daily model to the ESP model, some possible reasons are:
      - The daily model is using a temperature forecast that is either
        much above or below normal before reverting to normal
        temperatures in ESP.
      - If there is regulation (reservoirs, diversions, etc.) above the
        forecast point there may be differences between the two runs in
        how they are being handled. Please check with CBRFC forecasters
        for details on specific forecast points.
