Fire Danger Statement
National Weather Service San Juan PR
447 AM AST Mon Aug 17 2026

...ELEVATED FIRE DANGER EXPECTED ACROSS PUERTO RICO, VIEQUES,
CULEBRA, AND THE U.S. VIRGIN ISLANDS TODAY...

Critical fuel conditions persist across the islands, with extreme
drought affecting portions of eastern Puerto Rico and the southern
coastal plains. A drier airmass continues to promote mostly fair
weather across the region while keeping relative humidity levels
below critical thresholds. Combined with ongoing rainfall deficits,
stressed vegetation, and dry fuels, these conditions will favor
rapid fire spread.

The greatest concern remains across southern and southwestern Puerto
Rico, where fuels are exceptionally dry and recent fire activity has
been frequent. However, elevated fire danger extends across all of
Puerto Rico, Vieques, Culebra, and the U.S. Virgin Islands.
Consequently, a Fire Danger Statement is in effect from 10:00 AM to
5:00 PM AST. Residents and visitors are strongly urged to avoid
outdoor burning, as conditions will easily support wildfire ignition
and rapid spread.

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.
