The upper air sounding from this afternoon shows a drier trend compared to the sounding from last night. Satellite data also indicates thunderstorms have dissipated in the Samoan region, which suggests we are trending towards a more stable and dry pattern due to a weakening trough. This pattern prompted the cancellation for the Flash Flood Watch, though passing rain is still possible with remnant moisture associated with the trough. A light, east breeze will remain through Sunday, before gradually increasing Sunday night as a high pressure system builds near New Zealand. Expect trade winds to return for the new week. && .Marine... Latest wave heights from the Aunu`u PacIOOS buoy are around 10 feet, while peak periods average at 11 seconds (since this morning). Model data suggests wave heights subsiding overnight, however, average peak periods lingers around 10 seconds through Monday. This data suggests wave heights may fall below advisory thresholds overnight, though surfs (at the shore) may remain in the advisory threshold through at least Monday. .PPG WATCHES/WARNINGS/ADVISORIES...
