Weather Summary for Puerto Rico
National Weather Service San Juan PR
516 PM AST Thu Dec 1 2022

Low-level moisture and a northeasterly wind flow promoted passing
showers across the windward sections throughout the day. Showers
moved into the interior and southwest quadrant by mid-morning
into the afternoon. This activity produced brief periods of
moderate to locally heavy rains. Maximum temperatures were in the
mid 80s across most of the coastal areas with isolated areas in
the upper 80s. Winds were from the northeast at 10 to 20 mph,
with higher gusts around 25 mph and sea breeze variations.

We expect a mixture of clouds and clear skies across the local
islands. Showers will continue to reach the windward sections
overnight as pockets of moisture embedded in the trades reach the
region. Winds will persist from the northeast around 10 mph with
land breeze variations, and minimum temperatures will reach the
low-70s across the coastal areas and into the 60s in mountains and
valleys.

Across the regional waters, wind-seas will be between 3 and 5
feet tonight. Winds will continue from the northeast between 10 to
20 knots with higher gusts. There is a moderate risk of rip
currents along most of the north facing beaches of Puerto Rico.
