Weather Summary for Puerto Rico
National Weather Service San Juan PR
531 AM AST Fri Apr 20 2018

Fair weather prevailed across Puerto Rico and the adjacent islands
during the overnight hours. Isolated and brief showers were
observed over the local waters but none over land. The overnight
minimum temperatures were in the mid 70s across the lower
elevations and in the low to mid 60s across the higher elevations.

An increase in moisture is expected today. This increase in
moisture will combine with the local effects and daytime heating
to cause the development of showers and isolated thunderstorms
across several sectors in Puerto Rico. Daytime maximum
temperatures will be in the mid to upper 80s across the lower
elevations and in the upper 70s to mid 80s across the higher
elevations. Winds will increase to 15-20 mph with occasional gusts.

Small craft advisory continues in effect for seas up to 7 feet
across the Atlantic and Caribbean offshore waters and the local
passages. Moderate to high risk of rip currents today across all
of the local beaches.
