Weather Summary for Puerto Rico
National Weather Service San Juan PR
427 PM AST Mon Dec 18 2017

Partly to variable cloudy skies prevailed across the local islands
as a surge of trade wind moisture and accompanying showers
continued across the region. Some of these showers continued to
affect portions of the north and east sections of Puerto Rico and
the adjacent islands, as well as the coastal waters. Today`s high
temperatures were in the low to mid 80s along coastal areas.
Breezy conditions continued with winds mainly from the northeast
at 15 to 20 mph and occasional gusts between 25 to 30 mph in some

During the rest of the evening and overnight hours, the
prevailing northeasterly trades will continue to bring patches of
shallow moisture and periods of light to moderate rain across the
local waters and portions of the islands. However, the overall
weather conditions will be dominated by a persistent mid to upper
level ridge over the region in combination with a strong surface
high pressure across the Atlantic. This will support mostly fair
and breezy weather conditions, except for the occasional passing
trade wind showers followed by locally induced afternoon showers
each day. The afternoon showers if any should be focused mainly
across the central and southwest sections of Puerto Rico.

Across the regional waters...Seas up to 6 feet will continue
across most of the local waters and passages overnight. Winds
will remain from the east-northeast at 15 to 20 knots. For the
beach goers, there is a high risk of rip currents for most of the
northern facing beaches of Puerto Rico while a low to moderate
risk exists across the rest of the beaches.
