Expect this pattern to remain through Saturday before briefly diminishing Saturday afternoon as the high dips south. Breezy east winds are expected to diminish to 10 to 15 mph, occasionally reaching 20 mph at times through Monday. By Monday night, model guidance shows the high building again, returning breezy tradewinds through the end of the forecast period. Showers embedded within the trade wind flow are possible throughout this period. && .Marine... Latest wave heights observed at the Aunu`u PacIOOS buoy remain around 10 feet.
