534 FXZS60 NSTU 240115 AFDPPG Area Forecast Discussion National Weather Service Pago Pago AS 215 PM SST Sun Jun 23 2024 .Short term... Latest satellite data shows cool and dry air moving in from the south. If temperature models are correct, cool temperatures will extend through Tuesday as a strong ridge remains over the Islands. Expect the ridge to also produce breezy trade winds for this timeframe. However, as the ridge weakens Tuesday night, temperatures may return to normal conditions (Lows in the upper 70s, Highs in the mid 80s). .Long term... An east wind of 10 to 20 mph will dominate in the area for the rest of the forecast period. Expect scattered showers when warm air builds over the Islands midweek. Breezy winds and showers embedded within the trade wind flow will remain through next Sunday. .Marine... Latest observations observed at the PacIOOS buoy in Aunu`u and Poloa are around 9 feet. Wave heights will continue to build before leveling out Tuesday, though it is hard to tell the projected height as current wave heights exceed forecasted wave heights by at least a foot. Furthermore, the small craft advisory and high surf advisory will hold through at least midweek or may be extended due to dominant trade winds. && .PPG WATCHES/WARNINGS/ADVISORIES...
