Subject:     Experimental Hurricane Local Watch/Warning

             Product will Transition to Operational Effective

             June 1, 2015

 

Reference:   Service Change Notice 14-66 issued December 30,

             2014: Changes to the Hurricane Local Statement

             Effective June 1, 2015 

 

Effective June 1, 2015, the experimental Hurricane Local

Watch/Warning product issued by Weather Forecast Offices (WFOs)

in the Atlantic hurricane basin will become operational.

 

The Hurricane Local Watch/Warning product is a segmented,

automated product, with each segment being a discrete forecast

zone. Each segment contains land-based tropical cyclone

watches/warnings in effect, meteorological information, threats

(rain, storm surge, wind, tornadoes) and their potential impacts,

and local preparedness information.

 

This product is intended for parsing by the weather enterprise,

and is paired with the WFO Hurricane Local Statement (see Service

Change Notice 14-66 for changes to the Hurricane Local Statement

for 2015) to provide a complete, localized tropical forecast. 

The Hurricane Local Watch/Warning product will contain Universal

Geographic Code (UGC) and the following Valid Time Event 

Codes (VTEC):

 

TR.A - Tropical Storm Watch

TR.W - Tropical Storm Warning

HU.A - Hurricane Watch

HU.W - Hurricane Warning

 

Additional information on UGC and VTEC can be found in NWS

Instruction (NWSI) 10-1701 and NWSI 10-1703, respectively at:

 

http://www.nws.noaa.gov/directives/010/010.htm

 

 

The Hurricane Local Watch/Warning product replaces the Hurricane

Local Statement as the dissemination mechanism for land-based WFO

tropical cyclone watches and warnings. Tropical cyclone watches

and warnings for WFO marine zones will now be issued via the

Marine Weather Message (MWW) product. A Service Change Notice

detailing the change to the MWW will be sent out at a later date.

 

The National Hurricane Watch/Warning product (TCVAT(1-5))issued

by the National Hurricane Center is not affected by the addition

of the Local Hurricane Watch/Warning Product and will continue

unchanged.

 

A complete list of WMO Headers and AWIPS IDs for WFOs which will

issue the Hurricane Local Watch/Warning Product can be found at:
