943 FXZS60 NSTU 080037 AFDPPG Area Forecast Discussion National Weather Service Pago Pago AS 137 PM SST Fri Jun 7 2024 .Short term... A ridge continues to dominate in the region as fair weather and breezy conditions are observed in the area. Moisture from a trough just north of the Islands is anticipated to edge close through tonight. However, latest satellite data shows dry air associated with the ridge being more dominant than what models predicted. For this reason, expect isolated showers and breezy winds to remain in tonight`s forecast. .Long term... The aforementioned ridge will persist through Monday, which will extend isolated showers and trades for this timeframe. However, as the ridge finally recedes from the Islands Tuesday, this will allow for the trough to the north to migrate south. An uptick in showers will begin as the trough moves over the territory and winds turn from southeast to east. Numerous showers and breezy winds will remain through the end of the week. .Marine... A south swell and breezy winds will hold rough seas and high surfs in the area through the new week. Current wave heights are observed around 9 to 12 feet, which will slightly subside to 7 to 9 feet later tonight as the south swell passes further north. Hence, a small craft advisory remains in effect, while a high surf advisory may be upgraded to a warning on Monday. This is due to another round of strong south swells expected by this time. We anticipate impacts similar to yesterday`s events of dangerous surfs, ocean debris, and coastal inundation with the latter swells. .PPG WATCHES/WARNINGS/ADVISORIES...
