Weather Summary for Puerto Rico
National Weather Service San Juan PR
522 AM AST Thu Aug 17 2017

Cloudy skies and numerous showers with thunderstorms were
observed overnight. Rainfall accumulations associated with
these showers and thunderstorms were between 2 and 4 inches
particularly across northeast Puerto Rico. Strong gusty
winds were also observed with the thunderstorms.

Unsettled weather conditions will continue to prevail throughout
the day as an upper level trough interacts with a tropical
wave moving across the local islands. The chance for showers and
thunderstorms -squally weather type- will continue to be high
particularly during the morning hours across the eastern half of
Puerto Rico as well as across the local waters. Shower and
thunder development across western Puerto Rico this afternoon
will be dependent on cloud cover. Therefore, the potential for
urban and small stream flooding as well as strong gusty winds
continues. A slight improvement in the weather conditions are
expected on Friday. Another and stronger tropical wave is expected
to pass mainly south of the region Saturday.

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, eastern, and southeastern PR.
