Weather Summary for Puerto Rico
National Weather Service San Juan PR
352 PM AST Mon Jan 16 2017

Recent satellite imagery as well as the National weather service
doppler radar showed passing low level clouds and trade wind
showers moving across the coastal waters and parts of the islands
this afternoon. However, no significant rainfall affected the
islands, as the showers were fast moving and of short duration.
Afternoon high temperatures were in the low to mid 80s along
coastal areas, and in the low to mid 70s in higher elevations and
valleys. Winds were generally from the northeast between 10 to 20
mph with occasionally higher wind gusts.

Strong surface high pressure exiting the eastern seaboard of the
United States, will continue eastward across the west Atlantic to
maintain moderate east to northeast trade winds across the forecast
area at least through Wednesday. This prevailing trade winds
will continue to transport patches of shallow low level clouds
and brief showers across the islands at times. Most of these
showers should affect mainly the north 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. For the rest of the week expect
overall pleasant and seasonal type weather conditions over the
land areas.

Hazardous marine conditions will continue through at least mid-
week. Seas between 6 and 8 feet with occasional seas up to 10 feet
are expected to impact mainly the Atlantic waters and local passages.
Small craft advisories remain in effect for most of the coastal
waters. Marine conditions are expected to improve over the next
few days.
