This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Isolated thunderstorms throughout the day. Stay
alert and be prepared to take shelter if storms develop.

.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly in areas that experience
persistent or repeated rounds of heavy rain. There is a low
chance of isolated flash floods. Elsewhere, plan for water ponding
on roads and in poorly drained areas.

.Marine Conditions...Hazardous conditions for small craft in
areas with seas of 7 feet or higher, particularly across
the offshore Atlantic waters tonight. Small craft should exercise
caution elsewhere across the local waters.

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

.DAYS TWO THROUGH SEVEN...Sunday through Friday

The flood and lightning threat will persist over the next few days
but become more localized, driven by afternoon sea breeze and
diurnal convergence. Fresh winds and a weak northerly swell will
continue to produce hazardous marine conditions. The risk of life-
threatening rip currents will become high on Sunday, and
continue through early next week.

.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.
