Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
539 AM AST Tue Aug 22 2017

.DISCUSSION...Several days of wetting rains in the driest areas
and almost island-wide have raised fuel moistures considerably. A
drying trend is underway until the next wave on Wednesday-
Thursday. But scattered showers and isolated thunderstorms are
still indicated for much of western and interior Puerto Rico.
Isolated showers will also be seen in the islands east of Puerto
Rico including the U.S. Virgin Islands. Relative humidity values
are expected to remain above critical levels. Winds will diminish
somewhat today, but gusts in some areas will occasionally still
reach 15 to 20 mph. Fire danger is considered low.
