Subject: Tropical Cyclone Storm Surge Probabilities (2 Through
25 Feet) Become Operational in the National Digital
Guidance Database (NDGD): Effective June 1, 2011
Effective June 1, 2011, the tropical cyclone probabilities of
storm surge greater then 2 through 25 feet, at one foot
intervals, will become operational in the NDGD.
The products will only be available when a hurricane watch or
warning are in effect for the Atlantic or Gulf coasts of the
continental United States.
The directory containing the GRIB2 files will change from:
ftp://tgftp.nws.noaa.gov/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.sl
osh/AR.conus/
To (effective on June 1, 2011):
ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndgd/GT.sl
osh/AR.conus/
There is no change in the naming of the GRIB2 files. The GRIB2
file names of ds.psurgeabvNN.bin will continue to be used where
NN is the probability of greater then 2 through 25 feet at 1 foot
intervals.
If June 1, 2011, is declared a Critical Weather Day by the
National Centers for Environmental Prediction, this
implementation date will be postponed. Users will be notified of
that decision via another Service Change Notice and a new
implementation date will be established.
