Subject: Amended: Soliciting comments through November 30, 2016,

         on proposed changes to Tropical Cyclone Watch/Warning

         (TCV) and Hurricane Local Statement (HLS) products for

         Atlantic tropical cyclones affecting the continental

         United States

 

Amended to extend comment period through November 30, 2016

 

Effective immediately and continuing through November 30, 2016,

the NWS is seeking user feedback on proposed changes to Tropical

Cyclone Watch/Warning (TCV) and Hurricane Local Statement (HLS)

products for Atlantic tropical cyclones affecting the

continental U.S.

 

Specifically, the NWS is proposing implementing new storm surge

watches and warnings in association with Atlantic tropical

cyclones affecting the continental U.S. beginning with the 2017

hurricane season. These new storm surge watches and warnings

will be integrated within the TCV and HLS products.

 

All TCV products issued by the NWS during the 2017 season for

tropical cyclones originating in the Atlantic basin affecting

the continental U.S. would include Valid Time Event Code (VTEC)

for storm surge watches and/or warnings when conditions warrant. 

In addition, the NWS is proposing to expand the VTEC available

in TCV products issued by the National Hurricane Center (NHC)

for Atlantic tropical cyclones affecting the continental U.S. to

include all NWS-issued VTEC both along the coast and inland. 

Because of the increased information included, it is possible

that the NHC TCV product may not be sent until as much as 45

minutes after the NHC advisory package in some circumstances. No

changes are expected for the release times of the TCV and HLS

products issued by local Weather Forecast Offices (WFOs).

 

Changes to the HLS products issued by WFOs would be limited to

the "NEW INFORMATION" section of the product. The subsections

for "CHANGES TO THE WATCHES AND WARNINGS" and "CURRENT WATCHES

AND WARNINGS" would include storm surge watch warnings.

 

Information about the HLS product and VTEC can be found here:

 

http://www.nws.noaa.gov/om/notification/scn14-67tcv_aab.htm

 

Examples of the WFO and NHC issued TCV products with the new

format can be viewed at:

 

www.nhc.noaa.gov/experimental/tcv

 

If the NWS decides to make storm surge watches and warnings

operational in 2017, a Service Change Notice will be issued

announcing the effective date. No changes are being made to the

operational TCV and HLS products during the 2016 Tropical

Season.
