Weather Summary for Puerto Rico
National Weather Service San Juan PR
508 AM AST Tue Jan 17 2017

Showers moved across the islands at times. This activity produced
periods of moderate to heavy rains and gusty winds. However, these
showers moved fast enough and no significant rainfall accumulations
were detected. Early morning temperatures were in the lower to mid
70s along the coast and between the mid 50s and mid 60s across
mountains and valleys.

Strong surface high pressure continues eastward across the west
Atlantic to maintain moderate east to northeast trade winds across
the forecast area at least through Wednesday. As a result, patches
of moisture with clouds and showers are expected to move across
the islands at times. Most of these showers should affect mainly
the north, interior and east sections of the islands especially
during the late evening and early morning hours. This will be
followed by a gradual clearing and mostly sunny skies during the
daytime. Rainfall amounts should remain minimal across the islands
due to the rapid movement and short duration of any shower
activity. Pleasant temperatures, around the climatological values
for January, should prevailed across the islands.

Although marine conditions are slowly improving, hazardous marine
conditions continues mainly across the Offshore Waters and
Caribbean passages. Mariners can expect seas up to 7 feet with
occasional seas up to 9 feet. Small craft advisories remain in
effect for the offshore waters and Caribbean Passages. Marine
conditions are expected to improve over the next few days.
