These
Quantitative Precipitation Forecasts (QPF) are produced by the Hydromet Forecasters (HAS) at the
SERFC.
The SERFC routinely
includes 24 hours of forecast rainfall (QPF) through the
year. This QPF is used as input to river forecasts as well
as the SERFC and
National Significant River Flood
Outlooks. There is one exception. For
inland-moving tropical systems, the SERFC will use both the
first 24 hours of forecast rainfall (Day 1) and 60% of the
anticipated second 24 hour rainfall (Day 2). However, when
creating the daily
Significant Flood Outlook Maps,
the HAS forecasters and hydrologists at the SERFC use the
5 day forecast issued by
the
Hydrometeorological Prediction Center
(HPC), as guidance when making a decision of
whether to highlight an area that may receive Significant
Flooding.
