269 FNCA62 TJSJ 130900 RFDSJU PRZ014-015-027-132100- Fire Danger Statement National Weather Service San Juan PR 500 AM AST Fri Jun 13 2025 ...ELEVATED FIRE DANGER IS EXPECTED ACROSS SOUTHERN PUERTO RICO DURING THE MORNING AND EARLY AFTERNOON HOURS TODAY... Fire weather conditions have worsened across southern Puerto Rico as persistent dry and breezy weather continues, with official observing stations confirming over 6 hours of elevated fire danger yesterday. Today, especially between 9:00 AM and 5:00 PM AST, another period of elevated fire danger is expected. The Keetch- Byram Drought Index (KBDI), which reflects soil and surface fuel dryness, has risen to approximately 570 in Cabo Rojo and 607 in Gunica, indicating severe dryness that makes vegetation highly flammable. Rainfall over the past 30 to 60 days remains well below normal, at only 25% to 50% of typical amounts. Sustained winds of 15 to 20 mph, with gusts exceeding 25 mph, combined with low humidity between 45% and 55%, will increase the likelihood that fires will spread quickly if ignited. While fire risk is lower in other fire-prone areas such as Vieques and Saint Croix, fire spread cannot be ruled out there. Residents and visitors are strongly advised to avoid outdoor burning and exercise caution with any activities that could start a fire. If you see smoke or an active fire, please report it immediately by calling 9-1-1 or your local fire department. These dry and hazardous conditions are expected to persist through at least Saturday. Fire and emergency officials should be aware that weather conditions are becoming more conducive for the ignition and spread of wildfires. Fire danger statements are issued when fire weather conditions are approaching, but not meeting or exceeding, Red Flag Warning criteria. $$
