Partly cloudy skies with isolated showers and gentle to moderate trade winds prevail across the Marianas this afternoon. Ritidian buoy shows seas between 5 and 6 feet, while altimetry shows seas between 4 and 6 feet. && .Discussion... Little expected across the Marianas for the coming days. A dry trade-wind pattern is in place and looks to continue through at least the middle of next week. && .Marine... Gentle to moderate trade winds are expected to continue through the weekend. Combined seas of 4 to 6 feet will slowly subside over the next few days, dropping to between 2 and 4 feet Saturday. Seas are then expected to begin to build as a larger trade-wind swell moves into the region, reaching 4 to 6 feet Sunday night. The trade-wind swell will maintain surf high enough to result in a moderate risk of rip currents along east facing reefs. All other reefs are expected to have a low risk of rip currents. && .Eastern Micronesia and Chuuk... A fragmented Inter-Tropical Convergence Zone (ITCZ) will continue to weaken the next few days and shift west, but not without bringing intense showers and thunderstorms to Pohnpei through Wednesday. Seasonal patchy, showery trades are expected at Chuuk, Pohnpei and Kosrae for much of the forecast period, while Majuro will observe much more pleasant weather until the weekend. Combined seas of 3 to 5 feet are expected at all locations for much of the forecast period except for Majuro, where seas may increase an additional 2 to 3 feet during the weekend. && .Western Micronesia for Palau and Yap... A tropical disturbance centered near Palau is expected to bring intense showers and thunderstorms for the next few days to Palau, and through tonight at Yap, with gustiness possible near heavier showers. As the disturbance becomes an open wave and exits the region to the northwest, showers will taper down thereafter, but patchy seasonal showers are expected into next week. Combined seas of 3 to 5 feet may taper down a foot over the next few days, remaining as such into early next week. && .GUM WATCHES/WARNINGS/ADVISORIES... GU...None. MP...None.
