Fire Weather Planning Forecast for Puerto Rico
National Weather Service San Juan PR
436 AM AST Tue Jun 4 2024
.DISCUSSION...
The wetter pattern is still anticipated through at least
Wednesday as a tropical wave continues to affect the region
maintaining high moisture content across the area. Relative
humidities will range in the 60s and low 70s%, particularly along
the southern sections of Puerto Rico. Shower and thunderstorm
activity is expected to develop across Puerto Rico particularly by
this afternoon. The KBDI remains well below critical fire weather
values. Breezy conditions will prevail once again along the south
coast under the influence of the sea breeze and a departing
tropical wave. Therefore, the fire danger is LOW today.
