Weather Summary for Puerto Rico
National Weather Service San Juan PR
513 AM AST Wed Jul 18 2018

Partly cloudy and hazy skies prevailed across Puerto Rico
overnight. Some showers were noted across the offshore Atlantic
and Caribbean waters. Few showers were also observed moving across
inland Puerto Rico. These showers were moving quickly westward.
Minimum temperatures were in the mid 70s to around 80 degrees
across the lower elevations and in the upper 60s to low 70s across
the higher elevations. The wind was light and variable.

Local area remains under a stable air mass. This air mass is
maintaining relatively dry weather conditions across the region.
Saharan dust will continue to linger across the area through at
least Thursday. The chance for shower and thunderstorm activity
will increase on Thursday, associated with a tropical wave.

Across the local waters, east winds of 10 to 20 knots will keep
choppy seas between 4 and 6 feet across most of the local waters.
There is a moderate risk of rip currents across many of the local
beaches.
