Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
544 AM AST Sun Aug 20 2017

.DISCUSSION...Moisture in a band, extending out of a tropical
wave south of the Dominican Republic, which was once Tropical
Storm Harvey, will continue feeding across the local area today,
provoking numerous showers and thunderstorms. Although winds may
be gusty near thunderstorms they will be subsiding today and
tomorrow. Relative humidities will remain above critical levels.
Ten hour fuel levels have recovered from recent lows, with better
KBDI values, although Guanica and Cabo Rojo remain above 600.
Fire danger today is considered low and many areas are expected to
receive wetting rains. Isolated to scattered thunderstorms will
develop around midday.
