Weather Summary for Puerto Rico
National Weather Service San Juan PR
518 PM AST Fri Jan 18 2019


Mostly sunny skies prevailed across the island today, with east to
southeast winds of 10 to 15 mph. Light to moderate rain developed
across portions of the western and interior areas of the island and
caused urban and small stream flooding. Rainfall accumulations
ranged from one to two inches across some areas, while other
areas received less than a half of an inch.

Today`s high temperatures were near the lower to middle 80s in
lower elevations, while in higher elevations the temperatures
were near the lower to middle 70s. Showers are expected to
diminish just after sunset, but clouds will still remain across
the area with easterly winds of 5 to 10 mph. Tonight`s low
temperatures are expected to be near the upper 60s to lower 70s in
lower elevations, and the lower to middle 60s in higher
elevations.

A drier air mass is forecast to move into the region late tonight,
in addition the mid and upper level of the atmosphere will also
be dry. Therefore, a more stale air mass is expected to prevail
with a decrease in shower activity through the weekend.

Marine conditions will remain quiet through the weekend with seas
of 2 to 4 feet, with easterly winds of 10 to 15 kts. A low to
moderate risk of rip currents for the northern beaches of Puerto
Rico and the U.S. Virgin Islands.
