Subject: Changes in Fire Weather Forecast Zones for Southeast
Arizona Effective April 1, 2014.
Effective April 1, 2014 at 1100 AM Mountain Standard Time, 1800
Coordinated Universal Time (UTC), the NWS Weather Forecast Office
in Tucson, AZ (WFO TWC), will reconfigure and rename four fire
weather forecast zones. Upon implementation of this change, all
fire weather forecasts and related products for southeast Arizona
will use the zone number and name shown below.
WFO Tucson has fire weather forecast responsibility for the
southeast portion of Arizona. This zone reconfiguration better
fits U.S. Forest Service Ranger Districts and the prevailing
weather regimes in the area. The new zone numbers, names, and
description of the zone area are listed below:
WFO Tucson, AZ Fire Weather Forecast Zones
New Zone Code New Zone Name

This zone includes western Pima county, south central Pinal
county and the Tohono O’odham Nation.

county, Santa Cruz county and the western portion of Cochise
county. Mountains included in this zone are the Santa Catalinas,
Rincons, Huachucas, Whetstones, Santa Ritas, Patagonias,
Tumacacoris, and the Canelo Hills.
AZZ152 Southern Graham-Central and Eastern Cochise-
Southern Greenlee-Lower Elevations of the San
Carlos Apache Nation in Graham County-Coronado
This zone includes southern Graham county, central and eastern
Cochise county, southern Greenlee county and the southern portion
of the San Carlos Apache Nation. Mountains included in this zone

Gila Mountains are included in this zone.
These changes have been coordinated with the Tucson and
Springerville Dispatch Centers and other fire weather partners
and users in Arizona. Partners and users of WFO Tucson fire
weather products will need to update their system(s) to continue
receiving correct fire weather forecasts/products.
After these changes are implemented, Arizona fire zones AZZ146,
AZZ147 and AZZ148 will no longer be used.
