This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Isolated thunderstorms, particularly across
the western section. Stay alert and be prepared to take shelter
if storms develop.

.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across the southwest quadrant.
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), particularly
across coastal areas. Unsecured items could blow around.

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

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

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

The heat risk is likely to increase by Sunday and persist for the
rest of the forecast period. Tropical waves approaching the region
on Sunday through Tuesday will bring showers and thunderstorms,
enhancing flooding and lightning potential across sections of the
island, including Vieques and Culebra. Increasing winds on Monday
will bring back choppy seas and hazardous conditions for small
craft.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is encouraged. Please relay any information
about flooding, winds, waves, and rip currents to the National
Weather Service in San Juan.
