Weather Summary for Puerto Rico
National Weather Service San Juan PR
356 PM AST Wed Mar 21 2018

Partly cloudy skies prevailed across Puerto Rico during the
afternoon hours. Doppler radar detected scattered showers across
northwest sections of Puerto Rico, but no significant
accumulation was resulted from this activity. These showers will
dissipate late this afternoon or early in the evening. Elsewhere
across the local islands, not significant shower activity was
detected so far this afternoon. Maximum temperatures ranged from
the middle to upper 80s mostly across the northern coastal areas.
Winds were mostly from the east southeast at 10 to 15 mph.

For the overnight hours and Thursday morning expect fair weather
conditions with mostly clear skies and little to no shower
activity. Moisture is expected to increase over the local islands
by Thursday afternoon into the weekend as a frontal boundary
and associated surface trough move closer to the region. The
chance for shower activity and thunderstorm development will
increase Thursday afternoon as instability aloft, surface
convergence and moisture increase across the islands. Low
temperatures tonight would be in the low to mid 70s across lower
elevations and in the mid to upper 60s at higher elevations. Winds
will be mainly east southeast at around 10 mph.

Tranquil marine conditions will continue across the local waters
with seas of 2 to 5 feet and winds up to 15 knots through much of
the work week. Seas expected to increase by late Saturday or
Sunday. A moderate risk of rip current is in place for a few
beaches of Puerto Rico, including beaches of Vieques and Culebra.
