Weather Summary for Puerto Rico
National Weather Service San Juan PR
519 PM AST Thu Apr 19 2018

Scattered showers formed along the southeast and southwest coast
of Puerto Rico this morning with rainfall amounts ranging from 1
to 2 inches. This afternoon showers were over the eastern,
northeast, northwest, western and central Puerto Rico with most of
the activity dissipating before 4 PM today. The rapid erosion of
showers across Puerto Rico was caused by a more stable air mass
moving in from the east which limited the low level moisture to
feed the showers and isolated thunderstorms today.

Today`s high temperatures were in the middle to upper 80s across
lower elevations, and the higher elevations reached the lower to
middle 70s. Winds were out of the east southeast early today at 10
to 15 mph, then winds became easterly this afternoon.

Tonight wind will be out of the east at 5 to 10 mph with
temperatures near the upper 60s to lower 70s at lower elevations,
and the higher elevations will be in the lower 60s. Tomorrow
showers and isolated thunderstorms return across the region due to
an increase in low level moisture ahead of a weak trough.

A long period northerly swell resulted in life threatening rip
currents across the north, east and southeast facing beaches of
Puerto, Culebra, Vieques and St. Croix through Friday morning. A
small craft advisory is in effect for the offshore waters and
passages due to seas reaching 7 feet. Prevailing easterly winds at
10 to 16 kts across the area.
