Weather Summary for Puerto Rico
National Weather Service San Juan PR
529 AM AST Thu Sep 19 2019

Cloudy skies with showers were observed across most of Puerto Rico
through the overnight hours. The areas with the most rainfall were
the south coastal municipalities where over 2 inches of rain were
observed, only hundredths of an inch were observed elsewhere. The
overnight minimum temperatures were in the upper 70s to low 80s
across the lower elevations and in the upper 60s to mid 70s across
the higher elevations.

Light to moderate showers are expected in the morning hours
across most of Puerto Rico, while skies are expected to remain
mostly cloudy through the day. Showers and thunderstorms are
forecast across the northwestern quadrant of Puerto Rico in the
afternoon, with isolated to scattered showers expected elsewhere.
Daytime high temperatures are expected today to be in the upper
80s to low 90s across the lower elevations and in the upper 70s to
mid 80s across the higher elevations. Tropical Storm Jerry is now
located at 16.0N and 53.2W with maximum sustained winds of 70
mph. In its current forecast track, the center of Tropical Storm
Jerry would pass at over 100 miles north of the local islands on
Saturday. The main expected impact would be bands of showers and
thunderstorms approaching the local area. The local marine
conditions will also be hazardous.

Across the local waters, hazardous marine conditions due to a
northerly swell continue with seas up to 8 feet along the
Atlantic waters and local passages. Therefore, small craft
advisories are in effect. However, the large breaking waves
is expected to be over 10 feet, possibly to 14 feet, for that
reason a high surf advisory and a coastal flood advisory are also
in effect. Rough seas will continue through most of the forecast
period due to another swell associated to Hurricane Humberto and
the approaching Tropical Storm Jerry, that should move north of
the region during the weekend. There`s a high risk of rip currents
for the northern coast of Puerto Rico as well as for some beaches
along Vieques and Culebra.
