Subject: Changes in Fire and Public Zones for WFO Amarillo, TX,

         effective May 1, 2018


Effective Tuesday May 1, 2018 at 100 PM CDT, 1800 Coordinated

Universal Time (UTC), Weather Forecast Office (WFO) Amarillo

(AMA), TX, will divide the existing Randall County, TX, public

and fire weather forecast zone into two zones: a new Palo Duro

Canyon zone and a Randall County zone.


Specifically, the split will be along the rim of the canyon and

will encompass the Palo Duro Canyon within Randall County,

Texas. These changes are intended to provide increased

flexibility and improved accuracy of forecast for various

watches, warnings, and advisories in the public and fire weather

programs. The current zone is shown below in Table 1. This zone

will be split into two zones shown in Table 2.


The Fire and Public Zone changes require partners and users to

take appropriate action to receive the new zone products using

the Universal Generic Code (UGC) zone code format (Z) listed in

Table 2.

to ensure systems recognize the new UGC (Z) and new zone

alignments and names. These changes do not affect products using

county (C) UGC.
