FLASH FLOOD WATCH NOW IN EFFECT THROUGH TUESDAY NIGHT

Heavy rainfall observed via satellite over Upolu island is rapidly moving eastward towards American Samoa. Heavy rainfall with a flooding threat likely to begin within the next few hours with the possibility of an embedded thunderstorm. This heavy rainfall activity is part of a larger trough that should linger over the area through at least Tuesday night.

A southerly swell is beginning to move through the American Samoa coastal waters this evening to produce surf heights at High Surf Warning levels. This swell is forecast to strengthen throughout the overnight hours, peak on Thursday and remain at warning levels through Friday. The highest and most powerful surf will impact the southern shores of all islands.

Stay weather ready and monitor updates from the Weather Forecast Office American Samoa.

A 6.1 earthquake occurred in the Cuba region at 7 AM, June 8, 2026. There is NO TSUNAMI THREAT to American Samoa!

Adverse weather conditions are expected for American Samoa starting mid-week.

Wind: Trade winds will begin picking up on Tuesday. By early Wednesday, south-to-southeasterly winds could reach sustained speeds of up to 30 mph, with even higher gusts possible during passing trade wind showers. These breezy conditions are forecast to persist through the weekend.

Rain: As the winds increase, expect a rise in trade wind showers. By late week, we will be monitoring a slow-moving trough approaching from the north. Depending on its exact track and intensity, this system could bring heavy rainfall to the territory.

Seas: Rough seas will begin to develop late Tuesday due to the strengthening winds. Additionally, a powerful southern swell is projected to enter coastal waters by Wednesday, likely pushing surf to warning-level thresholds on Wednesday and Thursday. Hazardous marine conditions are expected to last until at least Saturday.
