Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
353 AM AST Mon Apr 23 2018

.DISCUSSION...The available moisture is expected to increase
today. There is also an upper trough moving in that will help in
the development of showers and thunderstorms this afternoon
across the interior into northwestern PR. Scattered showers
are expected elsewhere. The 10hr fuel moisture for the south
coastal plains of PR are near the critical thresholds, near 10%,
and the KBDI at Camp Santiago is over 600, but Cabo Rojo and
Guanica are both under 500. Because moisture is going to increase
today, the relative humidity is expected to remain above 50% and
skies could be variably cloudy. Wind speed is is expected
to be between 10 and 15 mph but could be higher at Cabo Rojo. Due
to the expected increase in moisture, the fire danger is expected
to be relatively low.
