Long term [Tuesday through Saturday]

The low pressure system will continue to move southward, closer to New Zealand with time. As the low pressure moves further away from the area, its impact on the wind field over American Samoa will decrease. This is forecast to lead winds to turn out of the east and slightly weaken by Tuesday, with showers decreasing to scattered Tuesday afternoon.

By late Thursday into Friday, a surface convergence (trough) is expected to develop over the islands. This is forecast to bring numerous to widespread showers over American Samoa by late week into next weekend. It is too early to determine if there will be potential for flash flooding at this time.

Tropical development is not expected within 300 nautical miles of American Samoa over the next 7 days.

Marine

Seas have not begun to build as quickly as models projected, and currently remain around 5 feet at Aunu'u and Poloa buoys. Still, as winds increase, seas are still likely to build to Small Craft Advisory levels (6 to 8 feet) tomorrow. With peak period times remaining in the 10 to 15 second range, High Surf Advisory criteria may be met as well tomorrow. These rough conditions should remain through Tuesday night, by Wednesday seas will subside due to decreased winds across the area.
