NOAA/NOS nowCOAST Status Message
725 AM EDT Mon June 12, 2017

Effective on or about June 12, 2017, a new version of NOAA's nowCOAST

(https://nowcoast.noaa.gov) will implemented. The new version will
incorporate the National Weather Service’s new Storm Surge Watch and
Warning with other NWS Watches, Warnings and Advisories for long duration
events on nowCOAST's map service,
wwa_meteoceanhydro_longduration_hazards_time. The spatial resolution of the
storm surge watch and warnings on nowCOAST will be at the original 2.5 km
(1.6 mi) resolution.  The storm surge watch and warnings will be also be
available via the nowCOAST map viewer.

The storm surge watch and warnings will be issued by NWS to highlight areas
along the Gulf and Atlantic coasts of the continental United States that
have a significant risk of life-threatening coastal inundation from ongoing
or potential tropical cyclone, subtropical cyclone, or post-tropical
cyclone events. Detailed information about the NWS Storm Surge
Watches/Warnings can be found at
http://www.nhc.noaa.gov/news/20170123_pa_SSWW.pdf and

In addition, the depiction of tropical cyclone forecast information on maps
available from the nowCOAST map service
wwa_meteocean_tropicalcyclones_trackintensityfcsts_time will change
effective on or about June 12, 2017.  These changes were made due in part
to modifications in NHC GIS data services and graphics depicting NHC’s
2-Day and 5-day Graphical Tropical Weather Outlook for Active Tropical
Cyclones and to promote more consistency with NHC products.  Additional
information about NHC changes can be found at

Summary of changes:

-  The 5-day cone of uncertainty representing the uncertainty in the
probable forecast track of a tropical cyclone will be depicted in
semi-transparent white.

-  The forecast positions for remnants, post tropical, tropical depression,
tropical storms and hurricanes will be depicted with new symbols and in

- The new symbol for hurricanes will contain the forecasted Saffir-Simpson
Hurricane Wind Scale Category (i.e. 1, 2, 3, 4 or 5).

-  The observed (best track) positions for tropical cyclones will be
depicted in white.

-  The forecast track for tropical cyclones will be depicted with a dashed
blue line.

-  The tropical storm warnings along the immediate coastline will be
depicted with a solid blue line.

NOAA’s nowCOAST provides coastal intelligence on present and future
environmental conditions
for coastal and maritime users by integrating data and information from
across NOAA and other federal and state agencies.  nowCOAST was
developed by NOAA/National
Ocean Service’s Coast Survey Development Laboratory, and is hosted on
NOAA’s Integrated Dissemination Program (IDP) infrastructure where it is
monitored 24 x 7 by NWS/NCEP Central Operations.
