Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
451 AM AST Sun May 28 2017

.DISCUSSION...High pressure ridge north of the region will maintain
light to moderate easterly trade winds of 15 mph or less, across the
forecast area for the next several days. A tropical wave will bring
an increase in moisture and instability, and also increase the change
for wetting rains across much of the islands Monday through Tuesday.
Relative humidity values may however briefly dip to the low 40s along
the south coastal plains today, however local sea breezes and moisture
advection will keep values above the critical thresholds. The risk of
fire danger is therefore expected to remain low for the next few days.
