This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Excessive Heat...This level of heat affects most individuals
sensitive to heat, especially those without effective cooling
and/or adequate hydration. Those extremely sensitive to heat face
the highest risk. Some health systems and heat-sensitive
industries could be affected. These conditions are most likely
across all lower elevations and urban areas.

.Wind...Breezy conditions (18-22 kts | 21-25 mph), particularly
across coastal areas of northern and southern Puerto Rico,
Vieques, and Culebra. Unsecured items could blow around.

.Marine Conditions...Small craft should exercise caution,
particularly across the Atlantic and Caribbean waters, including
the Mona Passage.

.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across northern, eastern, and southeastern
Puerto Rico, including Vieques, and Culebra. Isolated stronger
rip currents may occur elsewhere, especially near piers, jetties,
and channels.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

A limited to elevated excessive heat threat will likely persist
over the period. Breezy to locally windy conditions, while
offering little relief from the heat, will maintain a moderate
risk current risk, along with choppy, wind-driven seas through
the weekend, and again from Tuesday onward. Although isolated
afternoon thunderstorms may develop, particularly early next week,
they are not expected to produce significant flooding impacts.
Moderate to high concentrations of Saharan Dust will also persist
through at least Sunday, contributing to hazy skies and reduced
air quality. A tropical wave is expected to increase shower and
thunderstorm activity by midweek.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
