First Alert Weather: Big surf and building trade winds

We started off with a First Alert Weather Day and a Red Flag Warning… which has come to an end. Relative humidities have recovered to above 50 percent at PHNL and sustained winds are dropping below 20 mph. Since the threat for elevated fire weather concerns is diminishing, the Red Flag Warning has been cancelled. With a plume of moisture expected to move up the island chain tonight through Friday along with weakening trades, additional Red Flag Warnings are not anticipated to be needed over the next couple of days.
What can you expect? Breezy to locally strong trade winds and dry and stable conditions will continue into the evening hours. Showers will increase and winds will taper off tonight through Friday night as a trough and plume of moisture moves through. Then drier conditions are expected this weekend along with strengthening trade winds. Great viewing of the SUPERMOON tonight, it is 99.8% full and rises just before 6 PM.
Moderate to locally breezy trade winds are expected today with enhanced shower activity as a weak low level trough passes westward through the Hawaiian Islands. Trade winds will strengthen this evening as the subtropical ridge builds north of the state. Drier conditions are expected Tuesday to Wednesday, then an uptick in showers will be possible from Thursday into Saturday as another weak disturbance moves through the island chain.
Surf? This swell will slowly decrease through Thursday, with surf remaining well below advisory surf height thresholds. Surf along west facing shores should remain slightly elevated with wrap around north swell energy lingering into Thursday.
Surf heights along east shores will remain elevated and choppy tonight in response to short period trade wind swell over and upstream of the islands, but then then decline on Thursday as trades weaken. Expect tiny south shore surf through the end of the week due to small background swells.
Wishing you blue skies and much aloha.
