Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
459 AM AST Sat May 27 2017

.DISCUSSION...A drier airmass will encompass the region today. As
a result, relative humidity values will decrease somewhat along
the southern plains of Puerto Rico. However, lingering moisture
will keep values above critical levels. In addition, low level
winds will be mainly east at 10 to 15 mph. As a result, fire
danger is expected to be low.
