forecast to continue across the southern plains of Puerto Rico.
Soils are dry and there is plenty of fuels, winds are expected to
range between 10 and 20 mph and RH humidity will drop between the
low and mid 40s around noon. Therefore, there is an elevated fire
danger across the south coast of Puerto Rico and a RFD was issued.
