Weather Summary for Puerto Rico
National Weather Service San Juan PR
417 AM AST Wed May 22 2019

Mostly clear skies in the west and partly cloudy skies in the
east prevailed during the overnight and early morning hours.
Radar Doppler detected showers streaming over the waters with a
few of them moving inland over portions of southeastern Puerto
Rico. Significant rainfall accumulations were not reported with
this activity. Overnight low temperatures dropped into the mid to
upper 70s across coastal areas and into the mid to upper 60s in
high elevations. Winds were light and variable.

Showers will continue to move from the waters into portions of
southern and eastern Puerto Rico through the morning hours, moving
further inland as the day progresses. Then, shower activity
accompanied by isolated thunderstorms is expected to shift and
cluster across portions of the interior and western Puerto Rico in
the afternoon. Showers moving over the San Juan metropolitan
area cannot be ruled out. Favorable upper level conditions and
plenty of tropical moisture will support the development of deep
afternoon convection, resulting in rainfall accumulations up to an
inch and a half with isolated higher amounts. As a result, there
is an increasing potential for urban and small stream flooding,
particularly across the northwestern quadrant of the island.
Daytime high temperatures are forecast to peak in the upper 80s to
low 90s across coastal areas under an east-southeast surface wind
flow between 10-15 mph and higher gusts.

Across the regional waters and local passages, seas are expected
to remain at 4 feet or below. East to southeast winds will
continue between 10 to 15 knots. There is a moderate risk of rip
currents for the north facing beaches of Puerto Rico.
