As such, sea conditions have improved sufficiently to no longer pose a threat to small craft, so the Small Craft Advisory has been allowed to expire. $$ PMZ171-231900- /O.CON.PGUM.SC.Y.0061.000000T0000Z-260823T1900Z/ Yap Coastal Waters- 502 PM ChST Sun Aug 23 2026 ...SMALL CRAFT ADVISORY REMAINS IN EFFECT UNTIL 5 AM CHST MONDAY... * WHAT...Southwest winds 15 to 25 kt and seas 8 to 10 feet. * WHERE...Yap Coastal Waters. * WHEN...Until 5 AM ChST Monday. * IMPACTS...Conditions will be hazardous to small craft. * ADDITIONAL DETAILS...The last pulse of the monsoon is expected to continue to bring fresh to strong westerlies to Yap through midnight tonight, producing sea conditions hazardous to small craft.
