Weather Summary for Puerto Rico
National Weather Service San Juan PR
400 PM AST Fri Jun 23 2017

Partly cloudy skies prevailed across Puerto Rico this afternoon.
Doppler radar indicated isolated to scattered showers across
eastern, northeastern as well as across western interior and
southwest sections of Puerto Rico. This activity is expected to
dissipate rapidly around sunset. Winds were generally from the
east to east northeast at 10 to 15 mph with some higher gusts and
the maximum temperatures were in the upper 80s mostly in coastal
areas.

Isolated passing showers embedded in the prevailing easterly wind
flow are still expected overnight and early in the morning over
Vieques, Culebra and the eastern sections of Puerto Rico.
Although an upper level ridge will remain as the main weather
feature across the region for the next couple of days, locally
induced afternoon showers and thunderstorms are still possible
Saturday and Sunday across western and interior sections of
Puerto Rico. However, not significant or widespread precipitation
is expected as a drier air mass will continue to encompass the
region until at least Sunday. A tropical wave is expected to
reach the region Sunday night and Monday, increasing the chances
of showers and thunderstorms across the local islands and
surrounding waters.

Across the regional waters, mariners can expect seas of 3 to 5
feet and east winds between 15 and 20 knots. As a result, small
boat operators should exercise caution due to fresh winds. There
is a moderate risk of rip currents for most of the coastal areas
except for the east and west coast of Puerto Rico.
