StormLatest status
An active monsoon pattern has developed across Western Micronesia with recent satellite imagery showing broad areas of heavy showers and thunderstorms. Midday satellite-derived surface wind data depicts 15 to 20 mph west winds across Western Yap State and Palau. Computer models point to a continuation of these conditions into midweek with periods of heavy showers moving across the islands, occasionally bringing increased winds, gusts and choppy seas. Both Yap and Palau are in the monsoon inflow of JTWC's Invest 91W, (that is located near 11N144E between Yap and Guam). As 91W continues to organize showers are expected to remain widespread and heavy at times. Model guidance suggest up to 1 to 2 inches of rain a day through Wednesday, then tapering down to about 0.5 inch for the following few days. Residents should continue to monitor forecasts and listen for any marine advisories that may be issued over the next several days. Be aware of the latest weather conditions and trends before traveling between islands.
