Weather Summary for Puerto Rico
National Weather Service San Juan PR
438 PM AST Sun Jan 22 2017
Mostly high clouds covered the archipelago of Puerto Rico Sunday
afternoon. These clouds likely contributed to keep afternoon
temperatures on the cool side. Afternoon coastal temperatures
reached the lower to mid 80s with the temperature at the Luis
Munoz Marin airport only reaching 81 degrees. The afternoon
temperatures across the interior highlands ranged from the upper
60s to mid 70s.
Except for a few clouds and isolated light showers here and there,
mostly dry conditions should prevail at least through Tuesday.
Mean low level wind flow should become more southerly Monday as
the Atlantic surface ridge is displaced by a frontal boundary emerging
from the U.S. east coast. this will result in a warming trend,
especially across the northern half of the big island with
afternoon temperatures soaring into the mid to upper 80s. The
frontal boundary should approach the local Atlantic waters late
Tuesday night and this could bring an increase in showers toward
Pleasant marine conditions continue across the coastal waters,
with seas up to 5 feet and winds up to 10 knots. A moderate
northwest swell impacting the Atlantic waters will result in a
high risk of rip current across the Atlantic and northwest facing
beaches of Puerto Rico as well as the northern beaches of Culebra
island at least through Tuesday night. Marine conditions will
gradually deteriorate as the frontal boundary aforementioned
approaches our area.
