260 FXZS60 NSTU 140056 AFDPPG Area Forecast Discussion National Weather Service Pago Pago AS 156 PM SST Fri Jun 13 2025 .Short term [TONIGHT THROUGH SUNDAY]... Fair weather and breezy conditions continue as a dominant high- pressure system remains in place. The associated dry air is limiting shower development, as seen by the low-level cumulus clouds drifting through the area. This pattern in expected to hold through Saturday. By Saturday afternoon, conditions will begin to shift as the high-pressure system exits the region. Winds will gradually weaken, while moisture increases due to a weak boundary. Expect a higher chance of showers, though the potential for flash flooding remains low as the boundary doesn`t appear to be active. .Long term [MONDAY THROUGH FRIDAY]... Numerous showers are expected from Monday through Tuesday, followed by the arrival of another high-pressure system from the south on Tuesday night. This will reintroduce trade winds, which may strengthen, with wind speeds possibly reaching 20 to 30 mph for the remainder of the forecast period. && .Marine... Latest wave heights at the Aunu`u PacIOOS buoy are around 6 to 8 feet. Although seas are expected to subside Saturday following a diminishing wind trend, a large south swell is forecast to pass through coastal waters. Hence, a High Surf Advisory will likely continue for beachgoers as high surfs and strong rip currents will persist through Monday. Meanwhile, calm ocean conditions associated with light winds on Saturday may drop the small craft advisory for mariners. Overall, this pattern looks like high surfs near the shores, while over open waters remains calm for the Saturday through Tuesday timeframe. By Tuesday night, expect rough ocean conditions once again when trade winds return. .PPG WATCHES/WARNINGS/ADVISORIES... High Surf Advisory Small Craft Advisory && $$ TM
