Subject: Transition of Meteorological Model Ensemble River
Forecasts from Experimental to Operational Effective
January 8, 2013
Effective on or about January 8, 2013, the NWS Eastern Region
River Forecast Centers and the Southeast River Forecast Center
(RFC) will begin issuing operational meteorological model
ensemble river forecasts. These forecasts are online at:
http://www.erh.noaa.gov/mmefs/index.php
These ensembles use the temperature and precipitation output from
the National Centers for Environmental Prediction (NCEP) Global
Ensemble Forecast System Short Range Ensemble Forecasts and the
North American Ensemble Forecast System. These ensemble members,
and the current hydrologic model, are run through the RFC
Ensemble Streamflow Prediction System to generate a number of
possible river forecast outcomes. These outcomes are turned into
short-term probabilistic forecasts; graphics are generated using
the "R" graphics software.
These ensembles are complementary information to the official
river forecasts available online at:
http://water.weather.gov/ahps/
