Weather Summary for Puerto Rico
National Weather Service San Juan PR
458 AM AST Thu Apr 15 2021

Mostly clear to partly cloudy skies were observed across the
islands during the overnight hours. Minimum temperatures were in
general from the high 50s across the higher elevations to the low
70s across coastal areas. Winds were light with a northerly
component.

For today, a drier air mass will continue across the local area.
This will limit shower development across the islands, and
diurnally induced afternoon light showers may develop over
portions of the interior of Puerto Rico. Elsewhere, mainly sunny
skies are expected to prevail. Maximum temperatures are forecast
to reach the high 80s across coastal areas and winds are expected
to prevail from the northeast in general.

Across the regional waters, seas will range between 3 to 5 feet in
general and winds between 10 to 15 knots from the northeast are
expected through this afternoon. There is a moderate risk of rip
currents for the northern beaches of Puerto Rico.
