Implementing Improved Fire Weather Zone Coverage for Puerto Rico and the U.S. Virgin Islands
 
Effective Tuesday April 01, 2014 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.
 

All current fire weather zones will be changed to new zones or fire danger rating areas that have similar climate, fuel type and topography. The new fire weather zone map configuration will not match county boundaries. Fire weather zones will be changed from 9 to 13 zones starting Tuesday, April 01, 2014.
