This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Isolated thunderstorms, particularly across
the western side of the islands between 1 to 5 PM. 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 interior with the
peak of the showers and in areas were soils are already saturated.
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 all the coastal aside of Puerto
Rico, Culebra and Vieques from 11 AM to 2 PM.

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

.Marine Conditions...Hazardous conditions for small craft in
areas with seas of 7 feet or higher, particularly across
the Atlantic waters and the Anageda passage from 12 PM today.
Small craft should exercise caution elsewhere across the local
waters.

.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across |most of the coastal areas of
Puerto Rico, Culebra and Vieques. Isolated stronger rip currents
may occur elsewhere, especially near piers, jetties, and channels.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

The wind threat will continue from Tuesday into Wednesday around
the coastal areas. There is a potential to observed limited heat
threat across the coastal areas and urban sections. An increase in
moisture and instability will result in an increase in the
flooding and lightning threat for the islands.

.SPOTTER INFORMATION STATEMENT...

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