Weather Summary for Puerto Rico
National Weather Service San Juan PR
557 PM AST Fri May 29 2020

Partly to variably cloudy skies prevailed across Puerto Rico
through the morning hours. Then, during the afternoon hours,
showers and strong thunderstorms developed across northwest Puerto
Rico with rainfall accumulations ranging between a half an inch to
as much as 2 inches. High temperatures ranged from the upper 80s
to lower 90s across lower elevations to the lower to middle 80s
across higher elevations. Winds were generally from the southeast
between 10 and 15 mph with sea breeze variations.

Fair weather conditions are expected tonight and generally
throughout the weekend as a drier air mass along with suspended
Saharan dust particulates will prevail over the area. This will
limit the shower activity greatly across most of the area.
However, showers and isolated thunderstorms will be possible
across western and northwestern portions of Puerto Rico during the
afternoon hours due to local and diurnal effects. As a result of
the Saharan dust, hazy skies are expected.

Fairly tranquil marine conditions will continue throughout the
weekend with seas expected to range between 2 and 5 feet. A
moderate risk of rip currents is expected for the northern coast of
Puerto Rico as well as for the northeastern coast of Culebra.
