####018014915#### FNCA52 TJSJ 090824 FWFSJU Fire Weather Planning Forecast for Puerto Rico National Weather Service San Juan PR 424 AM AST Mon Feb 9 2026 .DISCUSSION... Fire danger will remain low overall today, though localized, short-term elevations are possible as the area begins an early drying transition. Despite above-normal rainfall during the past 30–60 days, fine fuels remain abundant and increasingly receptive, and KBDI values remain elevated across Cabo Rojo and Camp Santiago. Breezy to locally windy conditions may briefly favor fire spread in exposed areas; however, high relative humidity will continue to limit ignition and sustained growth. No significant fire weather concerns are expected at this time, but conditions will be closely monitored, and fire weather risk will be elevated and appropriate alerts issued if conditions warrant.
