Tropical Cyclone Rainfall Data
The HPC will issue public advisories after the National Hurricane Center
(NHC) discontinues its
advisories on subtropical and tropical cyclones that have moved inland,
but still pose a threat of heavy rain and flash floods in the
conterminous United States or adjacent areas within Mexico which affect
the drainage basins of NWS River Forecast Centers. The last NHC advisory
will normally be issued when winds in an inland tropical cyclone drop
below tropical storm strength, and the tropical depression is not
forecast to regain tropical storm intensity or re-emerge over water.
HPC advisories will terminate when the threat of flash flooding has ended.
