Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
531 AM AST Mon May 22 2017

.DISCUSSION...A drying trend is forecast for the next couple of
days as a dense mass of Saharan Dust will reach the local area.
RH will briefly reach 40-50 percent and winds around 15-20 MPH can
be expected at times. The limiting factor is the condition of the
fuels. At this time, most of the fuels remain green due to the
rains in early May. As a result...fire danger is low.
