Fire Danger Statement
National Weather Service San Juan PR
500 AM AST Tue Jun 17 2025

...ELEVATED FIRE DANGER IS EXPECTED ACROSS SOUTHERN PUERTO RICO
DURING THE LATE MORNING AND AFTERNOON HOURS TODAY...

Fire weather conditions remain hazardous across southern Puerto Rico
today, as very dry fuels, increasing winds, and a gradual decrease
in moisture contribute to elevated fire danger. While conditions on
Monday were less conducive due to slightly higher moisture and
lighter winds, today`s environment is more supportive of enhanced
fire spread.

During the period from 900 AM to 500 PM AST, elevated fire danger is
expected. The Keetch-Byram Drought Index (KBDI) continues to
increase, with current values around 586 in Cabo Rojo and 622 in
Guanica, indicating deep dryness. Rainfall deficits across the
region remain significant, with the percentage of normal
precipitation ranging from 10% to 50%, contributing to the
continued drying of soils and surface fuels.

East-southeasterly winds of 15 to 20 mph, with gusts exceeding 25
mph, along with relative humidity values between 40% and 50%, will
combine to support conditions favorable for fire spread,
particularly across wind-prone areas of the southern coastal plains
and adjacent hills.

Although nearby areas such as Vieques and Saint Croix currently face
lower fire danger, occasional fire spread remains possible under
locally favorable conditions.

Residents and visitors are strongly advised to avoid outdoor burning
and exercise extreme caution with any activity that may start a
fire. If you observe smoke or an active fire, report it immediately
by calling 9-1-1 or your local fire department.

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.
