Weather Summary for Puerto Rico
National Weather Service San Juan PR
456 PM AST Thu Aug 17 2017

An active tropical wave across the northeast Caribbean, produced
cloudy skies with numerous showers and scattered thunderstorms
across Puerto Rico and surrounding waters overnight, this morning
and early in the afternoon. Total rainfall accumulations
associated with these showers and thunderstorms were between 5 and
6 inches, particularly across southeast, eastern and northeastern
sections of Puerto Rico. Strong gusty winds were also detected
with the thunderstorms. Several flood advisories and flood
warnings were issued for municipalities and rivers over those
sections of the island. Winds were mostly from the east southeast
at 10 to 15 mph with strong gusty winds near showers and
thunderstorms. Due to the abundant cloud cover temperatures this
afternoon ranged from the lower to the middle 80s.

As the tropical wave continues to move westward, shower and
thunderstorm activity diminished rapidly by mid afternoon, leaving
mostly cloudy skies with limited shower activity over land areas.
However, showers and a couple of thunderstorms persisted across
the surrounding waters. Abundant cloudiness will continue across
the region during the rest of the afternoon and this evening but
not significant shower activity is expected as a relatively drier
air mass moved across the region behind the tropical wave. For
tomorrow afternoon, the available moisture is expected to combine
with daytime heating and local effects to produce some afternoon
showers and thunderstorms across interior and northwest sections
of Puerto Rico.

Mariners can expect seas between 5 to 7 feet and winds 15 to 20
knots. Therefore, small Crafts Advisories are in effect. In
addition, there is a high rip current risk across most of the
beaches in northern PR.
