An unsettled weather pattern remains in store for Palau and Yap for the rest of the week. A tropical disturbance, known as JTWC`s Invest 92W is centered just northwest Yap Proper, and is expected to further consolidate well northwest of Yap and Palau over the next few days. A series of southwesterly monsoon surges will continue to pummel both Palau and Yap as well. Model guidance has indicated significant stalling in development associated with Invest 92W, with little likelihood of developing into a significant tropical cyclone over the next 24 hours as it continues to move away from the main islands of Palau and Yap. Even so, the southwesterly monsoon trough and associated surges will continue to bring significant rainfall and thunder to Palau and Yap over the next few days. Due to the lackluster nature of the current stage of the monsoon and the aforementioned potential disturbance, variability in areas of convective development may produce periods of little to no weather followed by sporadic heavy showers and thunderstorms. In addition, high uncertainty remains regarding rainfall amounts, but the trend continues to indicate an additional 3 to 5 inches at Palau, and another 4 to 6 inches at Yap over the next 48 hours. At this time, landslides continue to be unlikely; however, if soils become saturated, any additional rainfall may quickly become runoff and increase mudslide risks, especially at Palau. While trade swells have weakened, localized wind waves and a developing southwest swell will produce choppy seas in Palau and Yap coastal waters over much of the week. Surf will continue to increase along south and west facing reefs of Palau and Yap, but are not likely to become hazardous at this time. Residents and mariners should monitor the latest forecasts for the region at weather.gov/gum/PublicForecasts and any information shared by WSO Palau and WSO Yap for their local regions. $$ Montvila
