Fire Weather Planning Forecast for Puerto Rico
National Weather Service San Juan PR
413 AM AST Fri May 10 2024

.DISCUSSION...

Soils are saturated and fuel vegetation is minimal due to
previous rainfall activity. A wet weather pattern with plenty of
tropical moisture and light winds will maintain the fire danger
low today. Showers and thunderstorms will develop across the
islands each day, especially during the afternoon, through at
least Saturday, then a drying trend is possible by next week.
