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/
