Quantitative Precipitation Forecasts
Quantitative Precipitation Forecast, or QPF, is a prediction of precipitation amounts over an area. In this case, the area is that of the LMRFC. QPF is created for six hour increments for the next 24 hour period. This is routinly done two times a day (00z and 12z), but can be at 06z and 18z if the weather dictates . The resultant LMRFC QPF is then used as an input into the hydrologic model and river forecasts are issued based on QPF.
