FIRE DANGER STATEMENT
NATIONAL WEATHER SERVICE SAN JUAN PR
501 AM AST SUN JUL 6 2025
...ELEVATED FIRE DANGER EXPECTED ACROSS SOUTHERN PUERTO RICO
TODAY...
FIRE DANGER CONDITIONS HAVE DETERIORATED, WITH AN ELEVATED RISK
EXPECTED TODAY ACROSS SOUTHERN PUERTO RICO, PRIMARILY DUE TO A
PROLONGED LACK OF WETTING RAINFALL. PRECIPITATION TOTALS OVER THE
PAST 30 TO 60 DAYS HAVE FALLEN TO JUST 5–10 PERCENT OF NORMAL IN
THE DRIEST SOUTHERN PLAINS AND HILLS. KEETCH-BYRAM DROUGHT INDEX
(KBDI) VALUES EXCEED 600 IN THESE AREAS, INDICATING SEVERE DRYNESS
AND HIGHLY FLAMMABLE FUELS. BACKING EASTERLY WINDS AND THE
ARRIVAL OF A DRIER AIR MASS TODAY WILL CONTRIBUTE TO LOWERING
RELATIVE HUMIDITIES TO BETWEEN 40 AND 55 PERCENT. PERSISTENT HIGH-
LEVEL CLOUDS MAY SLIGHTLY REDUCE DAYTIME HEATING BUT ARE UNLIKELY
TO INCREASE HUMIDITY OR PRODUCE RAINFALL, PROVIDING MINIMAL RELIEF
TO FIRE DANGER. BREEZY CONDITIONS—WITH SUSTAINED WINDS OF 15 TO
20 MPH AND GUSTS NEAR 25 MPH—WILL FURTHER ELEVATE THE POTENTIAL
FOR RAPID FIRE SPREAD, PARTICULARLY FOLLOWING IGNITION IN THE MOST
FIRE-PRONE AREAS OF SOUTHERN PUERTO RICO.
WHILE FIRE DANGER IS LOWER ELSEWHERE, THE RISK OF SPREAD CANNOT
BE RULED OUT, ESPECIALLY ACROSS THE CENTRAL MOUNTAIN RANGE AND
EASTERN INTERIOR, WHERE RAINFALL HAS ALSO BEEN WELL BELOW NORMAL.
RESIDENTS AND VISITORS ARE URGED TO AVOID OUTDOOR BURNING AND
EXERCISE EXTREME CAUTION WITH ANY FIRE-RELATED ACTIVITIES. REPORT
ANY FIRES OR SMOKE 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.
