Weather Summary for Puerto Rico
National Weather Service San Juan PR
540 PM AST Mon Jul 13 2020

It was variably cloudy across Puerto Rico today. Light showers
were seen in eastern Puerto Rico this morning and this afternoon with
amounts under one quarter of an inch. The best reported amount
was near San Lorenzo at Quebrada Arena with 0.24 inches. Rain was
still falling in western Puerto Rico around Las Marias where up to
one and a quarter inches have fallen. A thunderstorms was also
noted in the area. Winds were 10 to 20 mph with gusts as high as
30 mph near the north and south coasts. High temperatures ranged
from 93 degrees in Camp Santiago, Ponce and San German to the
lower 80s in the higher mountains. Some haze from Saharan dust
was noted.

Showers in the west will die down rather quickly tonight after
sunset. Isolated to scattered showers will persist in the eastern
hills of Puerto Rico from a weak line of moisture that stretches
east of the area. Winds will be less than 10 mph with land
breezes. Lows tonight will range from the lower 80s on the
windward coasts to the mid 60s in the higher mountain valleys.
Tomorrow will have less shower activity as mid levels become less
favorable to convection and moisture remains similar to today.
Highs will range from the lower 90s in the lower elevations to
around 80 degrees in the higher mountains. It will be breezy again
tomorrow with hazy skies from Saharan dust. Winds will be
easterly 10 to 20 mph with gusts up to 30 mph near the coasts.

Small craft operators are urged to exercise caution due to choppy
seas up to 6 feet and winds up to 20 knots. There is a moderate
risk of rip currents for most of the local beaches, except for
beaches along the western coast of Puerto Rico and around Ceiba.
