Weather Summary for Puerto Rico
National Weather Service San Juan PR
435 PM AST Wed Sep 18 2019

Plenty of clouds were observed today across most of the local
islands in association with a departing tropical wave located over
the Caribbean Sea. Although most of the rain activity remained
over the water, a few showers did move through areas of the main
island of Puerto Rico and Culebra. However, limited accumulation
was detected by the Doppler radar. Skies were hazy as well due to
Saharan dust. Temperatures reached the low 90s at lower elevations
and the upper-70s to lower 80s at the mountain with heat indices
as high as 100 to 105 degrees. Winds were out of the southeast at
10 to 15 mph with sea breeze variations.

Showers could enter tonight along the eastern and southern half of
Puerto Rico. The shower activity should continue into the morning
hours as well. Then, in the afternoon, due to the available
moisture and local effects, showers and thunderstorms could
develop along western sections of the Island. Saharan dust will
linger over the area as well. Temperatures will rise to the low 90s
at lower elevations and the upper 70s to low 80s at higher
elevations. Winds will be out of the southeast at 10 to 15 mph.

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. 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.
