...HIGH SURF ADVISORY REMAINS IN EFFECT FROM 6 AM THIS MORNING TO
6 AM CHST FRIDAY...
...HIGH RIP CURRENT RISK REMAINS IN EFFECT FROM 6 AM CHST THIS
MORNING THROUGH LATE THURSDAY NIGHT...

* WHAT...Large breaking waves of 7 to 9 feet and dangerous rip
  currents expected in the surf zone.

* WHERE...For the High Surf Advisory, north-facing reefs of the
  Marianas. For the High Rip Risk, north and east-facing reefs.

* WHEN...From 6 AM Wednesday to 6 AM ChST Friday.

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

* ADDITIONAL DETAILS...A shear line is stalled just north of
  Saipan while a pulse of northerly swell moves through the
  region. This increase in north swell, combined with the
  northeasterly trade swell, will continue to generate hazardous
  surf for north facing-reefs and a high risk of rip currents for
  north and east facing-reefs. Another pulse of north swell is
  expected to arrive Thursday, which will maintain these surf
  hazards into at least Friday morning.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.

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.
