Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
531 AM AST Thu Nov 23 2017

.DISCUSSION...Moisture will begin to increase today after mostly
sunny skies this morning. Some showers can already be seen
entering the forecast area in the local outer Atlantic
waters north of the U.S. Virgin Islands. Relative humidities are
expected to remain above critical levels. Winds will be light
until sea breezes begin but should remain below 18 mph except for
briefly higher winds near the coast. Showers could be heavy and an
isolated thunderstorm cannot be ruled out in interior, western
and southwestern Puerto Rico. Moisture will continue to increase
through Friday. Fire danger is considered to be low and soil
moisture also remains high. Drier conditions will return on
Saturday.
