Fire Weather Planning Forecast for Puerto Rico
National Weather Service San Juan PR
509 AM AST Fri May 31 2024
.DISCUSSION...
No significant change from yesterday`s discussion and overall
weather pattern. Although hazy skies are expected due to the
arrival of Saharan dust. Relative humidities could drop between
50-55% across the southern coastal plains of Puerto Rico. 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.
