Effective April 1, 2014, at 800 AM Atlantic Standard Time, 1200
Coordinated Universal Time (UTC), the NWS Weather Forecast Office
in San Juan, PR, will reconfigure the fire weather forecast zones
for Puerto Rico and the U.S. Virgin Islands to align with the
boundaries of the National Fire Danger Rating Areas. Upon
implementation of this change, all fire weather forecasts and
related products for PR and the USVI will use the zone number and

Specifically, fire weather zone PRZ020 was separated into 4 new
zones: PRZ025, PRZ026, VIZ001 and VIZ002 (including two new zones
for the Virgin Islands). Zone PRZ021 was separated into two
different mountain ranges: PRZ023 and PRZ024.
