This Hazardous Weather Outlook is for portions of Puerto Rico.

.DAY ONE...Today and Tonight

.Lightning...Scattered to numerous thunderstorms possible across
over the local waters and especially across the north coastal areas
and east sections of Puerto Rico early morning and in the afternoon.
Be aware of thunderstorms in your area, and plan to stop all
outdoor activity and move to shelters.

.Excessive Rainfall...Flooding of urban areas, roads, small
streams, and washes. Isolated flash floods possible.

.Excessive Heat...Heat index 102-107 degrees mainly across some
of the south, west and northwest to north central sections of
Puerto Rico.

.Wind...Breezy conditions mainly along the coastal areas.
Unsecured items could blow around.

.Marine Conditions..Seas equal or greater than 7 feet across
offshore Atlantic waters. Hazardous conditions for small craft..

.Rip Currents...Life-threatening rip currents are possible in the
surf zone across all beaches of Puerto Rico, Culebra and Vieques.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday
The outer bands of tropical storm Philippe will bring periods of
excessive rainfall and lightning hazard risk across the islands
and coastal waters through at least early Thursday. The potential
for urban and small stream flooding as well as flash flooding will
therefore remain moderate to high through Thursday. Mudslides
will also be possible in areas of steep terrain. Excessive heat
risks will remain in place mainly for some areas in the south
west and northwest Puerto Rico. Swells generated by Philippe will
maintain hazardous seas for small craft at least until Wednesday.
A moderate to high risk of life- threatening rip currents will
continue for the next few days.


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