Long term

For the beginning to mid-week, rainfall becomes below average. The trough, along with the potential tropical low, is to bring drier air in from the south over American Samoa and a ridge of high pressure enters the region. This will reduce the chance of showers to isolated to scattered (20 to 30% chance). Southerly winds may reaching up to 15 mph, but could reach up to 20 mph near Rose. For Tuesday and Wednesday, winds are to become variable as the trough moves further away from the region.

For late in the week, we will monitor a trough that is to develop near the Fiji region. For now, the trough is anticipated to remain away from the region and below average rainfall is to continue throughout the rest of the week.

Marine

The latest data from the PacIOOS buoy located to the east of Aunu'u shows seas around 6.5 feet and the King-Poloa buoy shows seas building to 6 feet throughout the morning hours. Even though sustained winds are gentle in many regions throughout the American Samoa coastal waters, wind gusts have occurred to locally build seas. However, the trough over the area is anticipated to remain over the region through the weekend. Also, by late Sunday and into early next week the area to the north and east of Rose is in region where there is a chance for tropical development. Winds well to the north of Tutuila, Aunu'u and Rose are to be a moderate westerly breeze, most other regions are to be a moderate southerly breeze on late Sunday and Monday with the exception of near the potential tropical development region.

Therefore, we expect seas to build on overnight tonight through the beginning of the week to around 6 to 8 feet, but locally higher to the north and east of the islands.
