...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 4 PM CHST FRIDAY...

* WHAT...Large breaking waves of 7 to 10 feet.

* WHERE...North and east facing reefs of Kosrae. North facing
  reefs of Pohnpei.

* WHEN...Until 4 PM ChST Friday.

* IMPACTS...Dangerous swimming and surfing conditions and
  localized beach erosion.

* ADDITIONAL DETAILS...A long period northerly swell emanating
  from a distant weather system combined with a large northeast
  trade swell continue to produce hazardous surf conditions for
  Pohnpei and Kosrae. Surf conditions look to remain hazardous
  through at least Friday afternoon. Model guidance suggest the
  north swell will subside slightly and then rebuild as another
  pulse is generated by a system near Japan, with the primary
  northeast swell still elevated. This may extend the high surf
  advisory into the weekend.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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