Weather Summary for Puerto Rico
National Weather Service San Juan PR
447 AM AST Mon Aug 20 2018

Variably cloudy skies persisted across the region overnight as low
to mid level clouds with occasional passing trade winds showers
moved across the local waters, and the north and east coastal
sections of the island. Most of the shower activity over land
was of short duration and of light to moderate intensity. Winds
were light and variable in most areas over land. Early morning
low temperatures were in the high 70s to near 80 degrees along
coastal areas and in the low to mid 70 in higher elevations.

Low level moisture trailing a tropical wave which was now over
Hispaniola, will continue to affect the region today. This along
with local and diurnal effects will support shower and
thunderstorm development mainly across parts of the interior and
west sections of Puerto Rico. The prevailing east southeast wind
flow should later steer the showers and thunderstorm activity
towards the northwestern quadrant of the island. Winds will be 10
to 15 mph with sea breeze variations and occasionally higher gusts
along the coastal areas. Highs will continue to reach the high
80s to low 90s along the coastal areas.

Across the regional waters, seas up to 5 feet are expected across
most of the local waters, except for coastal waters of southwestern
Puerto Rico where seas around 3 feet are expected. Winds will be
15 to 20 knots in some of the more exposed waters today, so
mariners should exercise caution. For the beach goers, there is a
moderate risk of rip currents for the beaches of northern and
southeastern Puerto Rico including around Guanica and the
southeast half of Vieques.
