First Alert Forecast: Cold front brings showers with breezy winds, drier weather due tomorrow
HONOLULU (HawaiiNewsNow) - A weak cold front approaching from the northwest and a prefrontal convergent cloud band over Oahu will slowly drift eastward down the island chain, stalling out over Maui County by Monday morning.
Clouds and periods of numerous showers will develop from Kauai to Maui into Tuesday. Winds will shift northeasterly and become locally breezy behind the front from Kauai to Molokai, then return to moderate speeds and fairly typical trade wind weather from Tuesday through the end of the work week.
Another front could shift winds southerly and bring an increase in showers next weekend for northwest islands and east to southeast slopes of the Big Island.
A flood advisory was posted for Kauai and Oahu but it has since expired.
A large NNW swell is building, and a High Surf Warning (HSW) has been issued for shores most exposed to the swell, with a High Surf Advisory for shores less exposed.
A small to moderate long-period NW (320 degrees) swell is expected Wednesday night and Thursday, followed by the potential for a very large NW (320 degrees) swell by the end of the week.
The high surf warning is in effect until 6 a.m. Tuesday for north and west facing shores of Kauai, Oahu and Molokai, where dangerously large breaking waves could near 25 feet.
The west facing shores of Kauai, Oahu and Molokai and north facing shores of Maui are under a high surf advisory for waves of 12 to 15 feet.
The dangerously large waves will be accompanied by powerful currents. Beachgoers should stay well away from the shoreline.
