Long term

By early next week, the SPCZ is forecast to weaken as it slowly moves south of the area. The likelihood of rain remains numerous (60% chance), pending on the exact location of the trough. Even if the trough remains over the region, the strength of the trough is to weaken. Northwesterly winds on Monday also weaken and becomes a light easterly breeze by midweek.

The PacIOOS buoys to the west of Tutuila and to the east of Aunu'u shows southeasterly and northerly swells moving through the American Samoa coastal waters. These swells had seas build up to around 8 feet throughout the day. However, period timing and strength of the swells are forecast to continue decreasing through the evening hours. The High Surf Advisory is likely to be lifted by late tonight/early Thursday morning.

We are monitoring the potential for the South Pacific Convergence Zone (SPCZ) to develop along the coastal waters on Friday through the weekend. This is forecast to create a moderate to fresh northwesterly breeze during this time, but may be stronger along the Pago Pago Harbor region. Seas are expected to be choppy with waves reaching up to 9 feet. Seas will slowly ease throughout the upcoming week.
