Subject: Change to the delivery time of Extratropical Surge and
         Tide Operational Forecast System for the Atlantic and
         Gulf coasts (ESTOFS Atlantic) effective January 7, 2014.
         ESTOFS Atlantic will be provided over SBN and NOAAPORT
         effective February 18, 2014

Effective January 7, 2014, beginning with the 1200 Coordinated
Universal Time (UTC) model cycle, the Extratropical Surge and
Tide Operational Forecast System for the Atlantic and Gulf coasts
(ESTOFS Atlantic) model output will be delivered 20 minutes
earlier than the current delivery time. This change in delivery
time is a result of optimization of the model code.

Effective February 18, 2014, beginning with the 1200 Coordinated
Universal Time (UTC) cycle, ESTOFS Atlantic will be added to the
Satellite Broadcast Network (SBN)and NOAAPORT. These grids will
be disseminated in GRIB2 format.

For technical details about ESTOFS please see: Technical
Information Notice (TIN) 12-43:

http://www.nws.noaa.gov/om/notification/tin12-43estofs.htm

ESTOFS output will be reprojected from the ADvanced CIRCulation
(ADCIRC) native finite element grid to the 2.5 km National
Digital Forecast Database (NDFD) Continental United States grid
and the 1.25 km NDFD Puerto Rico grid.

GRIB2 files will be created for each hourly prediction
(astronomical tides), and sub-tidal water levels (the isolated
surge). GRIB2 files will be available 6.5 hours after the
synoptic time (OO, 06, 12, 18 UTC.) The per cycle data volume
will be approximately 500 MB.

The WMO Headings for these products will be as follows:

   T1:     Data Format of GRIB2 - E
   T2:     Parameter code - C, E, or H
   A1:     Grid code - P for Puerto Rico or I for CONUS
   A2:     Forecast time interval- one of
           ABCDEFGHIJKLMNOPQRSTUVWXYZ
   II:     Layer or level: 88
   CCCC:   KWBM
