583 FXZS60 NSTU 010106 AFDPPG Area Forecast Discussion National Weather Service Pago Pago AS 206 PM SST Sun Aug 31 2025 .Discussion... Fair weather continues for the Samoa Islands. Low cumulus clouds are evident, which suggests stable conditions. However, model data shows an uptick in showers later tonight as a weak boundary develops in the area. The territory is forecast to lie at the edge of the ridge of high pressure extending from the southwest. Being in this sweet spot allows for enhanced moisture that could lead to passing showers and strong trade winds combined. The ridge will hold breezy easterlies through the end of the week as it continues to dominate. However, winds could reach advisory levels by Thursday when the high strengthens during its eastward track. Expect strong winds that could blow around unsecured objects as this plays out. By the weekend, the high pressure will exit the region. This will allow a trough to move in the area and produce numerous showers and light winds. && .Marine... Latest wave heights observed at the PacIOOS buoys remain below advisory thresholds, around 5 to 7 feet. Expect calm ocean conditions to continue through Monday until winds gradually build by the afternoon. East winds up to 20 knots are possible at this time, which will likely produce rough seas and prompt a small craft advisory. Additionally, seas will continue to build through the week as strong winds linger. Expect waves to peak at 9 feet or higher by Friday. .PPG WATCHES/WARNINGS/ADVISORIES... None && $$ TM
