Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
431 AM AST Thu May 25 2017

.DISCUSSION...A general drying trend is forecast to continue for
the next couple of days as a mass of Saharan Dust remain across
the local area. RH will briefly reach 40-50 percent and winds
around 15-20 MPH can be expected at times. However, the limiting
factor will continue to be the condition of the fuels. At this
time, most of the fuels remain green due to the rains of late
April and early May. As a result...fire danger threat is expected
to remain moderate today and during the upcoming weekend.
