Fire Weather Planning Forecast for Puerto Rico
National Weather Service San Juan PR
421 AM AST Sun Jun 30 2024
.DISCUSSION...
East winds with sea breeze variations are expected to range
between 10-15 mph with higher gusts along the southern coast of
Puerto Rico. After the passage of a tropical wave, a drier airmass
will filter into the region. KBDI values continue below the
critical threshold. Therefore, a low fire weather risk continues
across the islands today. Nonetheless, we urge people to stay
inform with our latest updates.
