## extract

Small Craft Advisory — Guam Coastal Waters; Rota Coastal Waters; Tinian Coastal Waters; Saipan Coastal Waters
Severity: Minor. Certainty: Likely.
* 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.
