Weather Summary for Puerto Rico
National Weather Service San Juan PR
430 AM AST Sat Apr 21 2018

Numerous showers and an isolated thunderstorm was observed over
eastern Puerto Rico and Vieques island during the overnight hours.
Some of these showers were moderate to heavy, causing minor urban
flooding in some areas. Rainfall accumulations were generally an
inch or less, but some isolated areas received just under 2 inches
of rain. The overnight minimum temperatures were in the low to
mid 70s across the lower elevations and in the 60s across the
higher elevations. The wind was mainly easterly at about 10 mph.

The higher moisture expected today will combine with the local
effects and diurnal heating to cause some shower and thunderstorm
development in the afternoon hours. The afternoon showers and
thunderstorms are expected to be mainly in the higher elevations
of Puerto Rico into the northwestern and north central sections.
In addition, a line of showers could affect the San Juan
Metropolitan area as well. There is only a slight chance of
showers across the lower elevations of the south coastal

A small craft advisory continues in effect for seas up to 7 feet
across the outer Atlantic waters. Small craft operators are urged
to exercise caution elsewhere due to seas of over 6 feet. There
is a moderate risk of rip currents today across all of the local
beaches, except for some of the beaches of western Puerto Rico.
