Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
522 AM AST Thu Oct 19 2017

.DISCUSSION...
A ridge is expected to builds aloft and a dry air mass is expected
to encompass the region today. As a result little or no shower
activity is expected across the islands today. Expect 20ft winds
between 15 and 20 mph and RH could reach near critical levels
today. However, saturated soils will continue across the islands.
