Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
542 AM AST Thu Aug 17 2017

.DISCUSSION...Fire weather danger is expected to remain low today
as wetting rains across the southern coastal areas of Puerto Rico
persisted overnight. This rain activity is associated to a
tropical wave that is crossing the island. Additional showers and
thunderstorms are expected through the rest of the morning hours
across much of the local islands. Drier conditions are expected on
Friday as an upper level ridge builds over the area and a brief
intrusion of Saharan dust is expected.
