Fire Weather Planning Forecast for Puerto Rico
National Weather Service San Juan PR
518 AM AST Tue Jun 25 2024
.DISCUSSION...
Once again, the east to southeast winds with sea breeze
variations are expected to range between 12-16 mph with higher
gusts along the southern coast of Puerto Rico. Relative humidities
should not reach critical fire weather thresholds as they will
remain below thresholds. Therefore, a low fire weather risk
continues across the islands today. Nonetheless, we urge people to
stay inform with our latest updates.
