Long term

A mid-level high pressure system is to form to the south of American Samoa on Monday night through Wednesday. During this time, this high may drag low to mid level moisture over the territory to increase the risk of rain in the region. Even though flash flooding is not expected, the chance of rain increases to scattered to numerous (50 to 60% chance) throughout this time. Winds are to remain a light easterly wind. More clouds than sun is forecast with temperature back to normal.

This high moves away from the territory in the middle of the week. A light easterly tradewind breeze is anticipated with only scattered showers, at best, for late in the week.

There is no risk of tropical development near the American Samoa islands for the next 7 days.

Marine

A southerly swell began to move through the American Samoa coastal waters this morning to elevate seas throughout the western, eastern, and southern waters along with surf along the southern shores. A High Surf Advisory is now in effect for southern shores through Sunday. A Small Craft Advisory will likely remain in effect throughout the day on Sunday and may expire as early as the evening hours. Both seas and surf are forecast to subside below advisory conditions by Monday morning. We will monitor another round of southerly swell on Tuesday night and Wednesday, but may not be strong enough to reach advisory levels. For Monday, early Tuesday, and late next week, benign sea conditions are forecast.
