Weather Summary for Puerto Rico
National Weather Service San Juan PR
458 PM AST Tue Jun 27 2017

Partly cloudy and hazy skies prevailed across Puerto Rico during
the morning hours and early this afternoon. Radar indicated only
isolated to scattered shower activity across interior and
southwest sections of Puerto Rico so far this afternoon. Not
significant precipitation was observed elsewhere across the
region. Winds were generally from the east at 10 to 15 mph with
some higher gusts and the maximum temperatures ranged from the
upper 80s to the lower 90s mostly in coastal areas.

Isolated showers activity are expected overnight and in the
morning hours across the eastern sections of Puerto Rico while
showers and thunderstorms are possible across the western sections
in the afternoon. This is due to the combination of the limited
available moisture, local effects, diurnal heating and some
instability. Daytime maximum temperatures are expected to be in
the low 90s across the lower elevations and in the mid 80s across
the higher elevations. Local winds expected to be from the east at
10 to 15 mph with sea breeze variations.

Across the regional waters, mariners can expect seas of 3 to 5
feet and east winds between 10 and 15 knots. There is a moderate
risk of rip currents for some beaches in Puerto Rico, including
the eastern beaches of Vieques.
