Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
508 AM AST Sat Apr 22 2017

.DISCUSSION...Drier air will continue to encompass the region
today. This will help relative humidities to decrease. Temperatures
are also expected to warm due to less cloud cover. Guidance
suggest possible critical values of relative humidities and winds
especially across the Guanica area today. Local winds are
expected to increase even more Sunday and Monday, but the expected
increase in moisture both day will maintain RH values above
critical values.
