This Hazardous Weather Outlook is for portions of Puerto Rico.
.DAY ONE...Today and Tonight
.Lightning...Isolated thunderstorms, particularly across north,
east and west Puerto Rico. Stay alert and be prepared to take
shelter if storms develop.
.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across western Puerto Rico.
There is a low chance of isolated flash floods. Elsewhere, plan
for water ponding on roads and in poorly drained areas.
.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 of Puerto Rico.
.Wind...Breezy conditions (18-22 kts | 21-25 mph), particularly
across northern and southwestern Puerto Rico. Unsecured items
could blow around.
.Marine Conditions...Small craft should exercise caution,
particularly across the Atlantic waters.
.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across beaches of north, east, southeast
Puerto Rico, Culebra and Vieques. Isolated stronger rip currents
may occur elsewhere, especially near piers, jetties, and channels.
.DAYS TWO THROUGH SEVEN...Wednesday through Monday
An elevated excessive heat threat will continue through Friday
across most lower elevations of PR. Isolated thunderstorms are
expected each afternoon over portions of the interior and western
PR. Breezy conditions and a moderate risk of rip currents will
prevail through the workweek. A tropical wave is expected to
increase shower and thunderstorm activity by midweek. A dense
Saharan Air Layer will return on Thursday, promoting hazy skies
and reduced visibilities through the weekend.
.SPOTTER INFORMATION STATEMENT...
Spotter activation will not be needed.
