Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
358 AM AST Sun Apr 23 2017

.DISCUSSION...A southeast low level wind flow will bring abundant
tropical moisture across the region today and through at least
the middle of the week. This wind flow will induce the development
of showers across the region with possible thunderstorms over
northwest Puerto Rico this afternoon. This will help relative
humidities to increase today. Temperatures are also expected to
decrease slightly due to increase in cloud cover. Local winds are
expected to increase today, but the expected increase in moisture
will maintain RH above critical values.
