DISCUSSION

Remnants of the trough to the south together with the low level open cell cumuli clouds from the north have been moving across the territory throughout the day. These features are associated with the brief passing showers, heavy, from time to time with hot temperatures. Model projections are showing the trough inching closer to the territory by Thursday. However, it remains slightly south of the islands until late Friday into Saturday, the trough will migrate over the territory and increase the potential for showers for this time frame. Model ensembles show the aforementioned trough oscillating north and south throughout the forecast period. Therefore, expect scattered to numerous showers with a gentle to moderate northwest wind tonight, decreasing to a gentle brreze on Thursday through at least Saturday. Winds will become variable for the rest of the forecast period.

Marine

Manual observations of the sea conditions from the last couple of days have been favorable for all water activities and mariners. Both PacIOOS buoy to the east and west of Tutuila Island show seas around 4 to 6 feet. Model projections has these heights remaining across the American Samoa coastal waters for tonight through at least Saturday. By Saturday night, seas will gradually build to 5 to 7 feet then further build to around 6 to 8 feet on Sunday. Will continue to monitor as more data becomes available.
