Weather Summary for Puerto Rico
National Weather Service San Juan PR
451 AM AST Thu Jan 17 2019

Occasional clusters of low to mid level moisture continued to
make its way across the forecast area and bring periods of passing
clouds and showers to the coastal waters and the windward side of
the islands during the morning. A weak low level trough just west
and north of the region will maintain a light east to southeast
wind flow across the area through at least Friday. Overnight low
temperatures were in the middle 60s to the lower 70s in lower
elevations, and the upper 50s to low 60s in higher elevations and
valleys. Winds were calm to light and variable.

Patches of low level moisture will continue to move across the
area through Friday, thus shower activity can be expected each
day. Some of the showers may be locally heavy at times resulting
in minor ponding of water on roadways and in poorly drainage areas.
Thereafter and over the weekend, moisture advection will slowly
diminish with mostly fair weather conditions expected. Winds will
become more east northeast and increase to 10 to 15 mph.

Marine conditions are expected to remain fairly tranquil today
with seas expected to range between 1 to 5 feet and east winds
between 5 and 15 knots. A northerly swell will continue to arrive
and spread across the Atlantic waters and passages over the next
few days. This will slightly increase the local Atlantic seas, as
well as create a moderate to high risk of rip currents along some
of the northern beaches of Puerto Rico, Culebra and Vieques.
