Implementing Improved Fire Weather Zone Coverage for Puerto Rico and the U.S. Virgin Islands
 
Effective Thursday August 6, 2015 at 800 AM Atlantic Standard Time (AST) or 1200 Coordinated Universal Time (UTC), the National Weather Service Forecast Office (WFO) in San Juan, Puerto Rico will adjust its current fire weather zones for Puerto Rico and the U.S. Virgin Islands.  This adjustment will provide improved fire weather warning and forecast services for PR and the USVI. The NWS Weather Forecast Office in San Juan, Puerto Rico, 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. Specifically, fire weather zone PRZ014 was split into two zones, PRZ014 Southeast Coastal Plains and PRZ027 Southwest Coastal Plains and Mona Island.
