Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
507 AM AST Tue Feb 21 2017

.DISCUSSION...Showers will continue to move over the islands
during the morning hours from the north due to the passage of a
weak surface boundary. However, a drying trend will follow quickly
and RH`s across the southern coastal areas are expected to drop to
the high 30s. Northerly winds are forecast to remain just below
critical levels.
