A long period southerly swell began moving through the American Samoa coastal waters overnight last night. This led to seas building to 8 to 9 feet, which was recorded by both PacIOOS buoys to the east of Aunu'u and to the west of Tutuila. As southerly swell continues to weaken for the rest of the day today and tonight, the High Surf Advisory for the southern shores will likely be canceled by late tonight and the Small Craft Advisory by early Monday morning. Seas are anticipated to ease to around 4 to 6 feet for Monday and Tuesday with benign conditions expected with a gentle easterly breeze and no significant swell.

By late Tuesday and Wednesday, another round of southerly swell is anticipated to move through the coastal waters. Seas are not expected to be choppy, but surf is anticipated to build throughout this time to at least near High Surf Advisory levels mainly for the southern coasts of Tutuila, Aunu'u and the Manu'a islands. Seas ease on Wednesday night and benign conditions are anticipated for the rest of the week.

PPG WATCHES/WARNINGS/ADVISORIES
