Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
444 AM AST Sun Dec 10 2017

.DISCUSSION...Winds are starting to diminish over the local area.
However, there are a few brief showers moving in through the
early morning hours. The relative humidity values are expected to
be in the 50s but with the light wind and stable atmosphere as
well as very low KBDI values across the islands, the risk of wild
fires is expected to be low today.
