Weather Summary for Puerto Rico
National Weather Service San Juan PR
530 PM AST Thu May 13 2021

Good moisture up to 8000 feet spawned showers that spread across
Puerto Rico and the southern half of Vieques during the day. No
thunderstorms occurred owing to the substantial capping in the
atmosphere, but a few spots in Las Marias, San Sebastian and along
the Hatillo Arecibo border had more than one half inch. San Juan
received three hundredths of an inch. Daytime highs were generally
in the mid to upper 80s in the lower elevations but Aguada did
reach 90 degrees today. Higher elevations were in the mid and
upper 70s. Winds were still breezy--especially along the coast.
Sea breezes of 10 to 20 mph with gusts to the 20s cooled the
island. Skies were variably cloudy with a slight haze in the air.

Showers will dissipate from land areas shortly after sunset, but
some moisture is still moving toward the area in east northeast
flow and will keep scattered showers in the forecast for eastern
Puerto Rico. Overnight lows will range from the mid to upper 70s
in the lower elevations to the 60s in the higher elevations. Winds
will diminish overnight to 10 mph or less. On Friday scattered
showers will continue in the east and spread across the island
during the day. Some heavier but short lived showers will also
form over west northwest Puerto Rico. Winds tomorrow should begin
to lose strength but will still be 8 to 18 mph with sea breezes
and higher gusts. Skies will be mostly sunny--especially in the
west during the morning and there will be a slight haze in the
air.

Across the regional waters, moderate to locally fresh easterly winds
will result in choppy seas of up to 6 feet mainly across the
Atlantic offshore waters, where small craft should exercise
caution. Seas of 5 feet or less and winds of less than 18 knots
are expected elsewhere. The rip current risk tonight will be high
along portions of the northwest to north central coast of Puerto
Rico and moderate for the remaining north and most east facing
beaches of Puerto Rico, as well as for all beaches of Culebra and
Vieques. The rip current risk will be only moderate or low on
Friday.
