...HIGH RIP CURRENT RISK REMAINS IN EFFECT FROM THIS AFTERNOON
THROUGH SATURDAY AFTERNOON...

* WHAT...Dangerous rip currents expected.

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

* WHEN...From this afternoon through Saturday afternoon.

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

* ADDITIONAL DETAILS...Long-period east to northeast swell, emanating
  from distant Typhoon Dolphin, is expected to develop a high risk of
  rip currents along north-facing reefs beginning tonight, with
  hazardous surf also likely to develop along north and east-facing
  reefs tonight. As Dolphin passes the far northern CNMI, the long- 
  period swell direction is expected to shift north early next week, 
  and then northwest. As it does so, a high risk of rip currents, and
  hazardous surf, is expected to develop along west facing reefs 
  later this week.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

AFTERNOON...

* WHAT...Large breaking waves of 8 to 12 feet and dangerous rip 
  currents expected in the surf zone.

* WHERE...North and east facing reefs of the Marianas.

* WHEN...For the High Surf Advisory, from 10 PM this evening to
  4 PM ChST Saturday. For the High Rip Current Risk, through
  Saturday afternoon.

* IMPACTS...Dangerous swimming and surfing conditions and
  localized beach erosion. Rip currents can sweep even the best
  swimmers away from shore into deeper water.

* ADDITIONAL DETAILS...Long-period east to northeast swell,
  emanating from distant Typhoon Dolphin, continues to produce a
  high risk of rip currents along east-facing reefs, spreading to
  north-facing reefs beginning tonight, with hazardous surf also
  expected to develop along north and east-facing reefs tonight.
  As Dolphin passes the far northern CNMI, the long-period swell
  direction is expected to shift north over the next few days, and
  then northwest around midweek. As it does so, a high risk of 
  rip currents, and hazardous surf, is expected to develop along 
  west facing reefs later this week.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Rip currents will be life threatening. Inexperienced swimmers
should remain out of the water due to dangerous surf conditions.

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
