Operational Forecast System (OFS)
OFS is a continuous river forecasting system which provides the forecaster with predictions of river flow to use in producing flood forecasts and other hydrologic products.

Parameter values are normally determined using the Calibration System and transferred to the Operational Forecast System through a manual preparation step.
This manual preparation is needed to add the description of operations for a given forecast (e.g., blend routines, different plot options)
