004 FNCA52 TJSJ 310909 FWFSJU 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.
