  Today & Tonight
A weak surface trough in the vicinity of the Samoan islands will likely introduced isolated showers and few thunderstorms mainly in the afternoon or evening as the atmosphere is slightly moist and unstable. Latest satellite loop this morning shows isolated convections near the island chain with persistent cloud band to the southeast moving westward slowly. This cloud band marked the active portion of the aforementioned surface trough. The upper level ridge to the north advects the upper level moisture over the forecast zone from the northwest which will support the development of showers and few thunderstorms. Global models suggest minimum showers with moderate east to northeast winds to persist throughout the short term forecast. Therefore, anticipate isolated showers with chance of moderate falls and few thunderstorms, with east winds to turn northeast later today.


Thursday into Saturday:
The ridge to the northeast will continue to build westward over the forecast zone and will be the dominant feature for the
early part of the long term forecast. Another trough of low pressure will developed just east of the Samoan island chain by early Friday morning with minimum showers. This aforementioned trough will introduced light variable winds by Friday into Saturday.


   Latest wave-watch model suggest waves and swells to remain below the advisory threshold throughout the forecast period.
