Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
332 AM AST Fri Dec 6 2019

.DISCUSSION...
A gradual drying trend is expected today and into the weekend as
a surface high pressure will build north and east of the region.
Any afternoon shower activity should be limited to the central
interior and west sections of Puerto Rico. Light to moderate easterly
winds between 10-15 mph will prevail. RH values may briefly drop
to the low to mid 50s along the south coastal plains, but will
quickly rebound with sea breeze variations. KDBI values are expected
to remain below the critical threshold values today. The risk of
fire danger will therefore remain low for today. However
continued drying of fuels and increasing trade winds over the
weekend and into early next week may increase the risk of fire
danger.
