Weather Summary for Puerto Rico
National Weather Service San Juan PR
550 AM AST Thu Jul 18 2019

Showers moved across many parts of eastern Puerto Rico overnight
but faded during the early morning hours. A few showers even
graced the south Coast around Santa Isabel. Winds were easterly at
less than 10 mph although showers were moving in from the east
southeast. Temperatures ranged from the mid 60s in the higher
mountain valleys to the lower 80s along the coast. San Juan had a
low of 79 degrees.

Scattered showers are expected during the morning hours in
eastern Puerto Rico, but the best showers and some thunderstorms
will be in the west northwest during the afternoon. A tropical
wave is approaching the area and will spread its moisture over the
area later tonight and on Friday. Highs today will range from the
lower 90s in some lower elevations to the mid 70s in the higher
mountains. Winds will range from 10 to 20 mph and strongest on the
coast where gusts up to 30 mph could be seen. Overnight lows will
return to the mid 60s to lower 80s but showers will be seen in
eastern Puerto Rico.

Seas up to 5 feet and east winds up to 20 knots are expected
today. Small craft operators will need to exercise caution in the
local waters off the north and south coasts and in the outer
Caribbean.
