Latest satellite data shows a weak line of cumulus clouds just south of the Islands. This indicates a weak trough that is forecast to move over the territory on Monday as a high pressure system builds behind it. However, due to the proximity of the trough, expect numerous showers and light winds tonight. On Monday, winds will slightly enhance as the high pressure pushes the trough north and over the American Samoa region. The Islands are forecast to lie at the edge of the high, with moisture anchoring at the boundary through midweek. Hence, scattered to numerous showers are expected for this duration. The high pressure system will strengthen by Wednesday as it moves east. Expect trade winds to return for the second half and showers embedded within the trade wind flow. .Marine... Seas continue to subside since Saturday, as winds have diminished. However, wave heights are currently within the 7 to 9-foot range, as measure by the Aunu`u PacIOOS buoy. This observation maintains seas within the advisory threshold (8 feet and higher). While ocean conditions are forecast to subside throughout the week, model data indicates a strong southeast swell moving into the area on Monday. These swells are anticipated to persist throughout the week, which means high surfs and strong rip currents will persist. && .PPG WATCHES/WARNINGS/ADVISORIES...
