Long term [Tuesday through Saturday]

Models indicate strong confidence in a weak surface low pressure system developing to the southeast of the territory and passing near the islands by midweek. As this low pressure system passes near the territory, winds are expected to slightly decrease to near or under 10 mph through the midweek period. As the low passes and moves west of the territory Friday through Saturday, winds are expected to turn out of the north to northeast and increase 10 to 20 mph. Rain chances are expected to increase to numerous showers Wednesday night through Saturday as the surface low moves near the area. Widespread flooding appears unlikely at this time.

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

Wave heights briefly peaked over 6 feet today at Aunu'u buoy due to wind gusts from heavy passing showers, but a subsiding trend is expected to reduce wave heights to 4 to 6 feet tonight. With no major winds or swells anticipated over the next few days, seas should remain in the 4 to 6 foot range through Tuesday.

Despite winds that are forecast to decrease to a light to gentle flow Tuesday night through Thursday, southeasterly swells may slightly increase seas 5 to 7 feet through this period. Additionally, longer period times elevate surfs and increase currents near the shoreline, but conditions should still remain below Small Craft Advisory and High Surf Advisory criteria.
