Puerto Rico in the afternoon and eastern Puerto Rico, including
Vieques and Culebra, later tonight. Stay alert and be prepared to
take shelter if storms develop.

drained areas, mainly over areas observing thunderstorm activity.
There is a low chance of localized urban and small streams
flooding.

across exposed coastal areas of southern and northern Puerto Rico,
Vieques and Culebra. Unsecured items could blow around.

areas with seas of 7 feet or higher, particularly across the
offshoreAtlantic waters. Small craft should exercise caution
elsewhere across the local waters.

beaches of Puerto Rico, Vieques, and Culebra. Isolated stronger
rip currents may occur elsewhere, especially near piers, jetties,
and channels.
.DAYS TWO THROUGH SEVEN...Monday through Saturday
Lightning and flooding risks will continue through the period,
mainly due to an approaching trough. The highest risk for both
hazards is expected during the first half of the week, especially
on Monday and Tuesday. Flooding coverage will increase through
Tuesday, then become more limited and localized later in the week,
with lightning risk also gradually decreasing toward the weekend.
Marine and rip current risks will remain limited, mainly driven by
breezy conditions.
