This Hazardous Weather Outlook is for Puerto Rico and the adjacent
Atlantic Coastal Waters.

.Day One...Today and Tonight

.Thunderstorms...There is a chance of thunderstorms with heavy
rainfall and brief gusty winds this afternoon across the northwest
quadrant of Puerto Rico. 

.Flooding...Heavy rains could lead to urban and small stream
flooding across northwest PR as well as across the San Juan metro
area. Mudslides in areas of steep terrain are also possible. 

.Wind...Sustained winds in excess of 20 MPH are expected across the
nearshore and offshore Atlantic and Caribbean waters. 

.Waves...Choppy seas up to 5 to 6 feet expected mainly across the
Atlantic waters. 

.Rip Currents...There is a moderate risk of rip currents for the north
facing beaches of Puerto Rico as well as across the beaches in 
southeastern and southwestern Puerto Rico, Vieques, and Culebra. 

.Days Two through Seven...Saturday through Thursday

Locally and diurnally induced showers and thunderstorms will develop
each afternoon, mainly across the northwest quadrant of Puerto Rico.
This could result in urban and small stream flooding as well as
mudslides in areas of steep terrain. Enhanced shower and thunderstorm
activity is possible on Sunday as a tropical wave in combination with
a mid to upper-level trough approaches the region. Therefore, the 
potential exists for more widespread urban and small stream flooding.

A moderate risk of rip currents will continue across several of the
local beaches during the next several days.  

.Spotter information statement...

Widespread spotter activation is not anticipated, however individual
spotter are encouraged to report flooding and rip currents to the 
National Weather Service in San Juan.
