Weather Summary for Puerto Rico
National Weather Service San Juan PR
500 AM AST Sun Feb 18 2018

Variably cloudy to partly cloudy skies prevailed across Puerto
Rico and the adjacent islands overnight, as passing clouds and
trade winds showers moved in and out of the region. While most of
the showers remained over the coastal waters, a few brushed the
north and east coastal sections of the islands. Accumulations were
however very minor. Winds were light and variable to calm. Early
morning low temperatures were in the low 70s along coastal areas.

Mainly fair weather conditions will prevail across the region during
the daytime. However, periods of passing low level clouds and occasional
showers will affect the region for the next several days under a cool
advective pattern. Limited afternoon shower activity is forecast each
day as an overall stable weather pattern will prevail except for the
quick passing showers and breezy conditions. Winds are forecast to
significantly increase by Monday and Tuesday, as the surface high
pressure ridge will build across the Atlantic just north of the
region. Cool and pleasant temperatures will continue with highs in
the low to mid 80s along coastal areas, and in the low to mid 70s
across higher elevations. Low temperatures will be in the high
60s to low 70s in higher elevations and valleys.

Choppy seas between 4 to 6 feet will continue across the regional waters
during the day but is expected to increase to 5 to 7 feet later tonight
as the trade winds increase. Marine conditions will deteriorate overnight
through the middle of next week, with wind driven seas of 7 feet
or greater expected. Small craft operators should exercise caution
across the local waters and passages. Small Craft Advisories will
be in effect starting later this evening and continuing through
Monday for most of the local waters.

There is a high risk of rip currents for the northwest to north central
facing beaches of Puerto Rico, and a moderate risk elsewhere except
for the west facing beaches of PR.
