Fire Weather Planning Forecast for Puerto Rico
National Weather Service San Juan PR
513 AM AST Wed Dec 4 2024

.DISCUSSION...

Above normal moisture content will continue over the islands,
resulting in RH values above critical levels, thus the fire
danger still low for the region. Winds will be mainly from the
east with speeds ranging between 8 and 14 mph and gusts up to 20
mph. Occasional showers will reach the windward sections
throughout the forecast period, and afternoon showers will develop
across the western sections.
