Bulletin details
* WHAT...Southwest winds 15 to 25 kt with gusts up to 30 kt and seas 7 to 10 feet. * WHERE...Yap Coastal Waters. * WHEN...Until 6 PM ChST Tuesday. * IMPACTS...Conditions will be hazardous to small craft. * ADDITIONAL DETAILS...As Super Typhoon Champi moves west through the Philippine Sea, it will help to generate a strong monsoon surge across Yap. Champi will also generate a large northwest swell that will interact with a secondary southwest to west swell and large wind waves to produce seas around 10 feet. As Champi moves far enough west, seas and winds will fall below Small Craft Advisory levels.
