Long term

From Monday afternoon until at least Wednesday night, weak easterly flow is forecast with a ridge of high pressure entering from the south/southeast. This is to give more sun than clouds throughout the day with isolated to scattered (20 to 30% chance) of passing showers. Otherwise, easterly trades of around 10 mph and above average temperatures are forecast in this time period.

For late in the week, we will monitor the potential for another trough to move into the region but severe weather from this trough is unlikely.

For the next 7 days, there is no potential for tropical development near American Samoa.

Marine

The latest data from the PacIOOS buoys from the west of Tutuila and to the east of Aunu'u shows seas just below the Small Craft Advisory levels. However, satellite imagery shows thunderstorms within a trough over the Samoan islands region. If thunderstorms develop, localized seas may reach around 8 feet. Therefore, the Small Craft Advisory continues through tonight until the trough moves away from the region around midday Monday. A gentle to moderate northeasterly breeze is to continue throughout this time, but wind gusts may occur near localized thunderstorms.

Around Monday afternoon, the trough is forecast to move away from American Samoa. Weak easterly trades are expected through at least mid-week with ideal sea conditions as there is no significant swell anticipated to move through the American Samoa coastal waters and seas are to ease to 4 to 6 feet.
