Long term

For next week, a low pressure system is anticipated to develop to the east of Rose Atoll and move away from American Samoa. As this occurs, drier air from the south is to move over the islands for the majority of next week. This will lead to below average rainfall, plenty of sunshine, and above average temperatures. Winds are to remain light.

The aforementioned low, to develop to the east of Rose, will be in an area of slightly favorable conditions for tropical development. If tropical development occurs, adverse conditions are expected to be well to the east of American Samoa. We will continue to closely monitor this area.

Marine

Conditions remain below Small Craft Advisory levels over the American Samoa coastal waters. However, during rainfall this morning the PacIOOS buoy to the east of Aunu'u showed building seas during rainfall in the area. Throughout the rest of the day today through at least Saturday, there is a possibility of heavy rainfall that may bring gusts to cause localized enhanced seas. Even though sustained winds and seas overall are projected to be below the Small Craft Advisory levels, be aware of potential thunderstorms and localized heavy rainfall.

Otherwise the trough is anticipated to move away from the American Samoa coastal waters in the beginning of the week, winds are forecast to be gentle with weak swell from the north. Therefore, ideal sea conditions are forecast for the majority of the upcoming week.
