...SMALL CRAFT ADVISORY NOW IN EFFECT UNTIL 4 PM CHST FRIDAY...

* WHAT...Seas 7 to 10 feet.

* WHERE...Marianas Coastal Waters.

* WHEN...Until 4 PM ChST Friday.

* IMPACTS...Conditions will be hazardous to small craft.

* ADDITIONAL DETAILS...Significant west to southwest swells
  continue to emanate from Super Typhoon Bavi (09W) and its
  trailing monsoon pattern, maintaining seas hazardous to small
  craft. Altimetry and Tanapag buoy data indicate combined seas
  sustaining at around 9 to 10 feet over western coastal waters of
  the Marianas as seas take longer to relax below hazardous levels
  than previously expected. So the Small Craft Advisory is
  extended through Friday afternoon, after which seas may fall
  below hazardous levels of 10 feet.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Inexperienced mariners, especially those operating smaller
vessels, should avoid boating in hazardous conditions.
