SPECIAL WEATHER STATEMENT

ISSUED: 3:50 AM DEC. 17, 2022 – NATIONAL WEATHER SERVICE
...VIGOROUS COLD FRONT EXPECTED TO BRING STRONG SOUTHWEST WINDS
AND THUNDERSTORMS LATE SUNDAY THROUGH MONDAY...

A powerful cold front is forecast to sweep across the state on
Monday. Southwest, or kona, winds will increase ahead of the front
on Sunday, with gusty conditions initially developing across
windward communities, as well as any locations over and downwind
of terrain. These strengthening winds may become damaging Sunday
night and Monday. Impacts could include roof damage, downed trees,
and power outages.

Thunderstorms may develop as early as Sunday, and some
thunderstorms could become strong to severe thunderstorms along
and ahead of the front Sunday night and Monday. Any thunderstorms
during this time frame could be capable of producing damaging wind
gusts and hail over any portion of the state.

Heavy rainfall is expected along the front and during
thunderstorms. At this time, chances for widespread flash flooding
do not appear to be high. However, leeward communities could
experience experience a period of heavy rainfall and potential
flood impacts, especially on Maui and the Big Island later Sunday
into Monday.

Additionally, the powerful low pressure system driving the front
will generate a very large and long-lived northwest swell that
will affect the islands from Sunday night through Tuesday.
Homeowners, beachgoers and boaters should prepare for high surf
and significant wave run-up, with possible coastal impacts along
exposed north and west facing shores.

Additional revisions to the forecast are likely as the event draws
nearer, and you should remain alert for later statements, watches
and warnings. Stay tuned to NOAA Weather Radio, local media and
internet sources for the latest information.

Sucks. Wishful thinking is that they revise this to say we won’t get killer winds.

36 people injured, including 11 seriously, after HNL-bound flight hits severe turbulence

HONOLULU (HawaiiNewsNow) - At least 36 people were injured, including 11 seriously, Sunday after a Hawaiian Airlines flight from Phoenix to Honolulu hit severe turbulence about 30 minutes before landing.

The turbulence sent some passengers flying out of their seats and at least one hit the ceiling.

Paramedics and emergency medical technicians treated passengers — ranging in age from 14 months to adults — for a long list of injuries, including serious head injuries, cuts, bruises and loss of consciousness.

Firefighters, ambulance crews and the federal Aircraft Rescue Firefighting Team were called to the airport about 11 a.m., meeting the aircraft at Gate 10A. Of those injured, 20 people were taken to emergency rooms.

Of those, 11 were in serious condition and nine were in stable condition, a Honolulu EMS spokesperson said.

The National Weather Service said the severe turbulence happened at about 36,000 feet.

“We believe the flight may have gone through a thunderstorm, which may have caused the severe turbulence,” said NWS meteorologist Genki Kino. “During that time, there were scattered thunderstorms everywhere.”

Someone onboard the flight identified it as Hawaiian Airlines Flight 35 from Phoenix to Honolulu.

Passenger Kaylee Reyes said the severe turbulence happened about 30 minutes before landing. Her mother had just sat down when the incident happened and hadn’t had a chance to buckle her seatbelt.

“She flew up and hit the ceiling,” Reyes said, adding the turbulence came out of nowhere.

Wow.

The NWS is currently predicting 135+ mph winds over the Big Island summits and blizzard conditions starting tonight and into Monday. 14 inches of snowfall expected.

Several years ago, similarly strong winds broke our anemometer and it took flight. IIRC it was found about a quarter of a mile away. I've also noticed significant icing on the summit today, so don't be surprised if wind readings from the summit start making no sense, they might ice up completely. It's happened before.

It's pretty wacky that the wind direction is all over the place among the telescopes. Is that because the buildings are shielding each other?
