Models are in fairly good agreement that rainfall totals will remain fairly low, with guidance showing less than 0.75 inch over the next 10 days. && .Marine... Marine conditions look to remain fairly uneventful over the next several days. Combined seas of 4 to 6 feet look to slowly subside to between 3 and 5 feet by midweek. Gentle to moderate trade winds are expected for the next several days. && .Eastern Micronesia... The trade-wind convergence is breaking down over the region. Spotty convection through out the region. There is a trough south and southeast of Majuro atoll, however, the convection associated with this trough is minimal. Otherwise not much is going on in eastern Micronesia. For the immediate future, scattered showers are anticipated through the region for the next week. Altimetry shows combined seas of 6 to 7 feet to the east of Majuro. Winds are expected to be moderate to fresh, diminishing over the week to gentle to moderate. All things considered, marine conditions are expected to remain below advisory levels of 10 foot seas and/or 22 knot winds. && .Western Micronesia... For Palau and Chuuk, persistent trade-wind troughs ripple through these islands. These troughs are what will bring scattered showers throughout the week. For Yap, a dry pattern remains present. Around mid-week, one of the trade-wind troughs is anticipated being large enough to bring much needed showers to Yap. However, by the weekend, the dry pattern will be back. Altimetry shows combined seas of 6 to 7 feet between Yap and Chuuk. Winds are expected to remain gentle to moderate through the week. Marine conditions are expected to be below advisory levels of 10 foot seas and/or 22 knot winds. && .GUM WATCHES/WARNINGS/ADVISORIES... GU...None. MP...None.
