Subject: Transition of NCEP HPC Probabilistic Quantitative
Precipitation Forecasts From Experimental to
Operational Effective April 5, 2011
Effective April 5, 2011, the National Centers for Environmental
Predictions (NCEP) Hydrometeorological Prediction Center (HPC)
will begin issuing probabilistic quantitative precipitation
forecasts (PQPFs) over the continental U.S. in 6 hour increments
out to 3 days. The PQPF forecasts provide information in two
different forms: probabilities of exceeding a threshold and
levels of precipitation amount associated with a given
percentile in the distribution.
The PQPF products are available online at:
