Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
535 AM AST Thu Apr 19 2018

.DISCUSSION...Although drier air is expected to filter over the
islands from the east during the day...enough moisture content and
an upper level trough will support the development of showers and
thunderstorms along portions of the Cordillera Central and western
Puerto Rico. Also, early morning showers and thunderstorms
affected much of the southeastern coastal plains. Therefore, fire
danger is expected to remain low today.
