Effective May 7, 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.  Please see Service

Change Notice 15-10.

 

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:
