Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
448 AM AST Thu Feb 22 2018

.DISCUSSION...Strong surface high pressure over the western
Atlantic will continue to result in breezy conditions across the
region through the end of the work week. A drier air mass will
limit shower activity along the southern areas of Puerto Rico
today. Relative humidities are forecast to range from the low to
mid 40 percent in southwestern Puerto Rico and sustained winds
should range from 10 to 15 mph with gusts in the low 20 mph.
Therefore, there is an elevated fire danger across the southwest
coastal plains today.
