Fire Weather Planning Forecast for Puerto Rico
National Weather Service San Juan PR
417 AM AST Sat Jun 1 2024
.DISCUSSION...
Expect hazy skies due to the arrival of Saharan dust. Relative
humidities will range around 50-55% in Camp Santiago and around
40-45% in Cabo Rojo. Shower and thunderstorm activity is expected
to develop over the northwest quadrant of Puerto Rico. The KBDI
remains well below critical fire weather values. Breezy condtions
will prevail once again along the south- southwest coast under the
influence of the sea breeze and a departing tropical wave.
Therefore, the fire danger remains low today.
