This Hazardous Weather Outlook is for portions of Puerto Rico.
.DAY ONE...Today and Tonight
.Lightning...Isolated thunderstorms, particularly across
northwestern and southeastern Puerto Rico. Stay alert and be
prepared to take shelter if storms develop.
.Excessive Rainfall...Ponding of water in roads and poorly
drained areas, particularly across northwestern and southeastern
Puerto Rico. There is a low chance of localized urban and small
streams flooding.
.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 coastal and urban areas, including Caguas, Culebra, and
Vieques.
.Marine Conditions...Small craft should exercise caution,
particularly across the Mona Passage and offshore Atlantic
waters.
.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across north facing beaches of the islands.
Isolated stronger rip currents may occur elsewhere, especially
near piers, jetties, and channels.
.DAYS TWO THROUGH SEVEN...Tuesday through Sunday
The heat risk will remain elevated through the workweek. Extreme
Heat Warning conditions are possible once again on Wednesday
across most urban areas of the lower elevations of the islands.
Afternoon thunderstorms could lead to urban and small stream
flooding each day over portions of northern and western PR. A
large, long period northerly swell will promote hazardous seas and
life-threatening rip currents from late Thursday through Sunday.
.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed.
