Global models suggest some isolated showers tonight into tomorrow afternoon before the trough shift further west of Savaii.

A tail-end of a frontal system to the south of the forecast zone will shift northeastward to the south of the main Samoan islands and will likely introduced some showers mainly to the southern parts of the main islands starting Wednesday evening towards Thursday afternoon. Another intense high pressure system behind the aforementioned fronts enter the forecast zone by Thursday night and will established the tradewind regime at the latter part of the long term forecast.

  

Aunuu wave buoy recorded swell height of 8-10 feet, thus warrant the validity of the small craft advisory as previously in effect.
