Weather Summary for Puerto Rico...CORRECTED
National Weather Service San Juan PR
525 AM AST Tue Aug 21 2018

Mostly clear to partly cloudy skies prevailed across the region
overnight. A few showers were noted moving west over the coastal
waters and brushing parts of the east coastal sections of Puerto
Rico. Most of the shower activity over land was of short duration
and of light to moderate intensity. Winds were calm to light and
variable in most areas. Early morning low temperatures were in the
high 70s to near 80 degrees along coastal areas.

Shower activity will diminish by late morning leaving mostly
sunny and fair weather skies across much of the island. However,
locally and diurnally induced showers and thunderstorms will again
be possible over parts of the interior and northwest sections of
Puerto Rico. The prevailing east southeast wind flow should steer
the afternoon 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 4 feet are expected across
most of the local waters, except for coastal waters of southwestern
Puerto Rico where seas around 2 feet are expected. Winds will be
around 15 knots in most of the local waters, except slightly higher
across the nearshore Atlantic and Caribbean waters, and the Mona Passage
were the wind could reach 15 to 20 knots and small craft
operators should exercise caution.
