379 FXZS60 NSTU 170110 AFDPPG Area Forecast Discussion National Weather Service Pago Pago AS 210 PM SST Thu May 16 2024 .Short term... A strong ridge will hold breezy conditions and a dry pattern over the territory through Friday. The upper air sounding from this afternoon as well as satellite data indicates a dry and stable atmosphere. Hence, east winds of 15 to 25 mph and isolated showers are expected through tonight. However, as the ridge slightly recedes southeast Friday morning, this will allow a trough to the north to move in the area. An uptick in showers and decreasing winds are possible in this scenario, so we anticipate numerous showers and moderate winds (Northeast at 10 to 15 mph) through Saturday. .Long term... The aforementioned ridge will build over the region once again by Sunday. Expect the trough to diminish, while breezy trade winds return with showers embedded within the trade wind flow. Hence, scattered showers and east winds of 15 to 25 mph will prevail through Monday. Thereafter, the ridge will gradually diminish in the area and east winds of 10 to 15 mph will hold for the rest of the forecast period. .Marine... Latest wave heights continue around 10 to 12 feet due to a combination of breezy winds and a south swell. Expect the high surf advisory and small craft advisory to hold through Friday with the aforementioned factors. However, the south swell will gradually diminish Friday, thus diminishing surfs, while choppy seas persist up to Monday due breezy conditions. && .PPG WATCHES/WARNINGS/ADVISORIES...
