Weather Summary for Puerto Rico
National Weather Service San Juan PR
527 AM AST Thu Apr 18 2019

Showers moved west across the local Atlantic waters about 5 to 10
miles offshore of Puerto Rico`s north coast and some did cross the
Caribbean sea south of the island. But, by 5 AM AST, only a few
crossed over land, leaving skies mostly clear or at worst partly
cloudy. The best amounts were about two tenths of an inch which
fell on the eastern side of El Yunque. Winds were easterly at 10
to 15 mph along the coasts during the early evening on Wednesday,
but quickly subsided to less than 5 mph in most areas.
Temperatures ranged from mid 70s in the windward lower elevations
to the 60s in the mid and upper elevations.

A few more showers will move over the eastern portion of Puerto
Rico and around Culebra and Vieques, but skies will be mostly
sunny this morning. Then, after noon, showers will develop in
western Puerto Rico, and, to a lesser extent, the interior
portions of the island. Some of these showers could be heavy
enough to cause some minor ponding in poorly drained areas. Winds
will increase during the morning hours to 10 to 20 mph with a few
gusts as high as 30 mph on the north coast. Temperatures will
return to the mid to upper 80s in the lower elevations and to the
70s in the mid and upper elevations.

Easterly winds of 15 to 20 knots in the near shore waters of the
Atlantic and Caribbean will necessitate that mariners exercise
caution. Elsewhere over the local waters, winds will be 10 to 15
knots with choppy seas of 3 to 5 feet. There is a moderate risk of
rip currents across all of the northern beaches of Puerto Rico,
the eastern beaches of Vieques and the northeastern half of
Culebra, as well as the southeastern and western beaches of the
south coast of Puerto Rico.
