...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH WEDNESDAY
AFTERNOON...

* WHAT...Dangerous rip currents expected.

* WHERE...East facing reefs of the Marianas.

* WHEN...Through Wednesday afternoon.

* IMPACTS...Rip currents can sweep even the best swimmers away
  from shore into deeper water.

* ADDITIONAL DETAILS...The arrival of long-period north-northeast
  swell will increase surf along north and east facing reefs. Surf
  will build to 7 to 9 feet along east-facing reefs first, then surf
  along north-facing reefs may increase to the high rip risk and
  high surf threshold tonight and Monday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Rip currents will be life threatening. If caught in a rip
current, relax and float. Don't swim against the current. If
able, swim in a direction following the shoreline. If unable to
escape, face the shore and call or wave for help.

...HIGH RIP CURRENT RISK WILL EXPIRE AT 4 AM CHST EARLY THIS
MORNING...

Buoy data at Ipan and Ritidian Point have shown a downward trend in
the significant wave height and in the peak and mean periods of the 
swells affecting the Marianas. This data indicates that the east and 
northeast swells are no longer supporting hazardous surf of 9 feet 
and have allowed the risk or rip currents to drop from high to 
moderate. Continue to practice general water safety when swimming or 
doing other water activities as rip currents are still possible, 
especially near cuts in the reef when surf is elevated.
