This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today

.Lightning...Isolated thunderstorms, particularly across
west 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 west Puerto Rico.

.Excessive Heat...Limited risk across the local islands. This
level of heat affects primarily those individuals extremely
sensitive to heat, especially when outdoors without effective
cooling and/or adequate hydration.

.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across the north facing beaches. Isolated
stronger rip currents may occur elsewhere, especially near piers,
jetties, and channels.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

The risk of rip currents along the north-facing beaches of Puerto
Rico and the U.S. Virgin Islands is expected to increase tonight
into Friday as a northerly swell spreads across the local waters.
As a result, life-threatening rip currents are likely within the
surf zone. There is a high chance of urban and small stream
flooding on Sunday, as moisture levels are expected to reach their
highest values during the forecast period.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
