Weather Summary for Puerto Rico...CORRECTED
National Weather Service San Juan PR
528 AM AST Sat Nov 17 2018

Mostly cloudy skies prevailed over portions of Puerto Rico during
the overnight hours. Fast moving showers embedded in the easterly
trades winds continued to move over the eastern and interior
areas of the island during the overnight hours and this morning.
However, due to their fast movement rainfall accumulations were
light. Winds were out of the east at 10 to 15 mph. Overnight
temperatures were near the middle 70s to lower 80s near lower
elevations, and the middle 60s in higher elevations.

Today scattered showers are possible during the afternoon across
the eastern, interior and western areas of Puerto Rico. However,
due to drier air working into the area later this morning and
during the afternoon convection will thwarted from developing
into thunderstorms. Today`s high temperatures are forecast to
reach the middle to upper 80s in lower elevations, and the middle
70s to lower 80s in high elevations. Winds will be out of the east
at 10 to 15 mph with higher gusts possible.

Across the regional waters...Seas ranging between 5-7 and up to 8
feet will continue. Winds will be between 15-20 knots with higher
gusts across the forecast area. As a result, Small Craft
Advisories still in effect for most marine zones. There is a high
risk of rip currents in effect for beaches along the northern
coast of Puerto Rico and Culebra.
