157 FXZS60 NSTU 030102 AFDPPG Area Forecast Discussion National Weather Service Pago Pago AS 202 PM SST Wed Jul 2 2025 .Short term... TONIGHT THROUGH FRIDAY...A moist airmass that triggered heavy rainfall last night and this morning continues to move westward. Showers have diminished since, and a drier weather pattern is expected through the weekend. The strong high pressure system from previous forecasts will maintain breezy trade winds, reaching near advisory thresholds (25 mph or greater) Thursday as the high continues to build. Passing showers will persist across the Islands for the short term forecast. .Long term... SATURDAY THROUGH WEDNESDAY...As the aforementioned high moves southeast, expect winds to gradually diminish Saturday. Latest models suggest southeast winds of 10 to 15 mph will persist through the new week, instead of the breezy winds that were expected from another high pressure system developing near New Zealand. It seems the latter high isn`t as strong as the current one. Will continue to monitor the long term forecast with new information available. && .Marine... Rough and hazardous seas will continue through the weekend, peaking on the July 4th Holiday as winds near advisory thresholds build to the east. Wave heights may build to 12 to 14 feet for the Friday through Saturday timeframe. Even as seas gradually subside Sunday, wave heights are still expected to be around 9 feet, until Monday. && .PPG WATCHES/WARNINGS/ADVISORIES... High Surf Advisory Small Craft Advisory && $$ TM
