...HIGH SURF ADVISORY REMAINS IN EFFECT FROM 6 AM WEDNESDAY TO
6 AM CHST FRIDAY...
...HIGH RIP CURRENT RISK REMAINS IN EFFECT FROM WEDNESDAY 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 swimmers 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 generate hazardous surf for north facing reefs and a
  high risk of rip currents for north and east facing reefs come
  Wednesday morning. Another significant 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.
