Long term [Friday through Tuesday

The trough to the south of the territory will strenghten late week into the weekend while slowly moving closer to the area. This trough should maintain the northeasterly flow across the region through at least Saturday. Heavy rainfall assoicated with the trough will initially remain south of the territory. However, by Saturday night into early next week, the trough is forecast to move closer to the area and bring an increase in rainfall. Thunderstorms and flash flooding may become threats over this period. The highest confidence in the potential for flash flooding at this time is Sunday into Monday, but the threat for heavy rainfall may continue into Tuesday depending on the exact positioning of the trough.

Marine

Seas have continued to subside beyond yesterday's forecast, now observed around 5 feet at the Aunu'u and Poloa buoys. With no major swells or increases in winds expected, seas should remain steady in this 4 to 6 foot range throughout the forecast period. However, heavy showers and thunderstorms may elevate seas at times on Sunday.
