This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Isolated thunderstorms. 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 primarily those
individuals extremely sensitive to heat, especially when outdoors
without effective cooling and/or adequate hydration. These
conditions are most likely across urban and coastal areas.

.Wind...Breezy conditions (18-22 kts | 21-25 mph). Unsecured
items could blow around.

.Marine Conditions...Small craft should exercise caution across
most local waters.

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

.DAYS TWO THROUGH SEVEN...Monday through Saturday

An area with slightly drier air and suspended Saharan dust
particles will move in by Monday, creating hazy skies and
deteriorating air quality. Winds and choppy seas will continue to
promote life- threatening rip currents across exposed beaches.
Limited localized flooding and lightning risk, along with a
moderate rip current risk, limited to possibly elevated heat risk
and limited marine and wind risks will persist through most of the
week. Late Thursday into Friday, the approach of a mid- to upper-
level trough/low and a tropical wave could increase flooding and
lightning risks.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
