Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
530 AM AST Wed Mar 22 2017

.DISCUSSION...Increasing low level moisture across the region will
support shower development across much of the island during the next
several days. East to southeast winds between 5-15 mph will prevail
except for the local sea breeze variations in some areas. RH values
my briefly dip to the mid to high 40s along the south coastal plains
but is expected to remain above the critical thresholds. Therefore
the risk of fire danger is expected to remain low.
