Description: 
A tropical disturbance, formerly known as JTWC's Invest 99W has been upgraded to a Tropical Depression 06W (Jangmi), and is currently centered near 9.9N 137.3E, about 61 miles west-northwest of Yap Proper. Jangmi is expected to continue consolidating over the next few days as it moves further north-northwest into the Philippine Sea. Numerous to widespread showers and isolated thunderstorms are seen along the southern, western, and northern peripheries of Jangmi. Heavy rainfall and gusty winds are expected across much of Palau and western Yap State, including Yap Proper this week. As Jangmi lifts northward this week, the developing monsoon tail will continue to intensify along the south side. Westerly to southwesterly winds of 20 to 30 kt with gusts peaking near 40 kt are expected. This will cause seas hazardous to small craft and hazardous surf. A large band of heavy showers are occurring over Palau along the surge in monsoon inflow/tail. For Yap, deepening convection is expected to continue building in and across the area as Jangmi gradually consolidates nearby. Seas of 8 to 12 feet are expected through Friday morning.
