Fire Weather Planning Forecast for Puerto Rico

.DISCUSSION...
Dry and stable weather conditions are expected to prevail today.
Relative humidities are expected to lower to around 50%. However,
the current KBDI and fuel moisture does not support elevated fire
weather conditions. In addition, rain was observed yesterday in
the south due to remaining moisture of a cold front that passed
in the previous days. Therefore, the risk for fire danger will be
low for today.
