480 FNCA62 TJSJ 130608 RFDSJU PRZ014>019-022>027-VIZ001-002-132000- Fire Danger Statement National Weather Service San Juan PR 208 AM AST Thu Aug 13 2026 ...ELEVATED FIRE DANGER EXPECTED ACROSS ALL OF PUERTO RICO... VIEQUES...CULEBRA...AND THE U.S. VIRGIN ISLANDS TODAY... A very dry and increasingly windy air mass will spread across the local islands today, with little to no wetting rainfall expected. Easterly winds of 15 to 20 mph with gusts around 30 mph will combine with widespread vegetation and crop stress, ongoing rainfall deficits, and increasingly dry fuels. The greatest fuel stress remains across southern and southwestern Puerto Rico, where recent fire activity has also been more frequent, but elevated fire weather conditions are expected across Puerto Rico, Vieques, Culebra, and the U.S. Virgin Islands. Elevated fire danger is expected today, with conditions likely to continue or worsen Friday and Saturday as the very dry air mass persists, winds remain strong, and fuels continue to dry. Any fires that develop may ignite more easily and spread rapidly. Residents and visitors should avoid outdoor burning and use caution with activities that could generate sparks or open flames, especially where vegetation is dry or stressed. Fire and emergency management officials should be prepared for an increased potential for wildfire ignition and rapid fire spread. Fire Danger Statements are issued when fire weather conditions are approaching, but not meeting or exceeding, Red Flag Warning criteria. $$
