Starting February 1, 2014, the NWS San Juan Weather Forecast Office will be able to issue, when necessary, additional products to provide more guidance on how possible conditions could be conducive to rapid or explosive growth of any wildfire that develops.
The new products our office could issue, when necessary are the following:
RFW - Fire Weather Watch (Vigilancia de Riesgo de Incendios) or Red Flag Warning (Aviso de Bandera Roja/Aviso de Riesgo Elevado de Incendios)
These will be issued when the combination of fuels and weather conditions support extreme fire danger and/or fire behavior.

Our office already issues the Routine Fire Weather Planning Forecast for Puerto Rico (FWF) every morning with a short discussion of the current and forecast conditions and a general, zone-based information for daily preparedness and planning purposes. Also, Spot Forecast Product (FWS) can be issued after a request is made by local, state or municipal agency. This site-specific forecast is issued for wildfires, prescribed fires, search and rescue operations, aerial spraying, etc and is available upon request at any time of day, week or season, following the requirements outlined in the NWS directive NWSI 10-401.
