955 FXZS60 NSTU 030106 AFDPPG Area Forecast Discussion National Weather Service Pago Pago AS 206 PM SST Sun Jun 2 2024 .Short term... Rainfall continues to diminish in the area as a strong ridge builds to the south. Models have been spot on at forecasting the flooding and intense winds experienced overnight through this morning. For this reason, our confidence in the forecast for the next few days is high. A dry pattern is expected as the aforementioned ridge continues to dominate in the area. Hence, flooding conditions and winds have fallen below watch and advisory thresholds leading to the cancellation of the flood watch and wind advisory. Scattered showers and a breezy trend will hold through Tuesday. .Long term... By Tuesday night, model data suggests the ridge will weaken and allow for a trough to the north to descend over the Islands. Expect an uptick in showers by this time with the potential for flooding to remain through Wednesday. However, a similar weather pattern seen today is possible Thursday as the ridge to the south strengthens once again. .Marine... Latest wave heights recorded via SOFAR drift buoys are around 10 to 12 feet. A High Surf Warning was dropped today as wave heights have fallen below 15 feet. However, a high surf advisory and small craft advisory remains in effect due to rough conditions produced by the current wind pattern. Model trends depicts seas diminishing through Tuesday as windspeeds continues to diminish. However, a strong south swell will likely keep seas in advisory thresholds through the end of the forecast period. && .PPG WATCHES/WARNINGS/ADVISORIES...
