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.
