Weather Summary for Puerto Rico...CORRECTED
National Weather Service San Juan PR
742 AM AST Sat Jul 24 2021

During the overnight hours, partly cloudy skies were observed
across most of the region. Overnight temperatures were near the
middle to upper 70s. Winds were from the east ranging from 10 to
15 mph. GOES-16 and SJU doppler radar show showers and
thunderstorms moving across the local waters, Vieques, Culebra,
and northern and eastern Puerto Rico. The activity will continue
to increases across the areas mentioned above through the morning
hours. This activity will produce frequent lightning, and moderate
to heavy rains that could lead to urban and small stream flooding
and localized flash flooding over portions of northeast Puerto
Rico.

This afternoon, as the wave moves westward, it will interact with
an upper-level low to the northwest of Puerto Rico. The upper-
level low and tropical wave will cause favorable conditions that
will support numerous showers and thunderstorm development over
the western, interior, and northwestern areas of Puerto Rico this
afternoon. Urban and small stream flooding is likely due to the
moderate to heavy rainfall. Today`s high temperatures are forecast
to be near the middle 80s to lower 90s in lower elevations and
the middle 70 to lower 80s in higher elevations. Winds will be
from the east ranging from 10 to 20 mph with higher gusts.

For the local waters, moderate to fresh easterly winds will
prevail over the local waters through at least Sunday, causing
choppy marine conditions. Seas up to 7 feet for the outer Atlantic
waters today. Therfore, a Small Craft Advisory is in effect for
the outer Atlantic waters. Small craft should exercise caution due
to seas up to 6 feet across the Caribbean waters and Anegada Passage.
