Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars, and the sunrise and sunset too…depending upon weather conditions.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Wednesday comments:  I’m here in Bend, Oregon, visiting my good friend Bob Earle, who is a professor of Physical Geography and GIS at the local college. I hope you have a good Wednesday wherever you happen to be spending it.

It’s cloudy here in Bend, with a low temperature of 33.5 degrees in Bob’s backyard in NW Bend.

It’s remained cloudy with off an on mostly light showers, along with breezy conditions at times too. The temperature is 39.5 degrees, which easily qualifies as cold rain in my mind.

Bob and I are heading up into the eastern Cascade mountains soon, as it’s snowing not far from here in Bend. I’m of course going to be dressing as warmly as I can! We plan on hiking around until it gets too cold, and forces us back into the car.

 

Hawaii’s Broad Brush Weather Overview:  Windy trade winds will persist into the weekend. Showers will focus along windward and mountain exposures, reaching leeward sides of the smaller islands.

Hawaii’s Weather Details:  A strong high north of the state is generating robust trade winds across the islands today. Atmospheric soundings at Hilo and Lihue show a strong 8-10,000 foot inversion in place across the area. Satellite and radar show a band of showery clouds over and just upstream of Maui County and the Big Island.

Expect mostly light to moderate showers to quickly pass mainly for windward slopes of the islands, with some showers spilling over to leeward areas of the smaller islands, due to the elevated trade wind inversion. Look for a slightly drier trend later this afternoon. Trade wind showers are likely to increase again tonight into Thursday.

The high to the north will strengthen as a cold front weakens and is pushed southward. Trade wind speeds will begin to increase today. A wind advisory has been issued for select windy areas around Maui County and the Big Island through Thursday. This advisory will likely be extended and expanded for Friday and Saturday.

Model guidance remains on track with winds continuing to strengthen and possibly peak Friday through Saturday near High Wind Warning speeds for select locations. A High Wind Watch may need to be issued later today. The remnants of a dissipated front mentioned above may arrive late Friday into Saturday. This may translate to an increase in cloud cover and showers as this feature passes through, for both windward and leeward sides of the islands. Wind speeds will slowly taper down Sunday into Monday (but still remain fairly breezy) with showers focusing along windward and mountain areas.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Vog map animation

Fire Weather: Trade wind speeds are forecast to exceed sustained 20 mph at Honolulu airport Friday and Saturday, with higher speeds in more exposed areas around the state. It is also possible for winds to also reach 20 mph on Thursday while ramping up, and on Sunday while trending down. The limiting factor will be relative humidity, which is expected to stay in the upper 40’s to lower 50’s around Honolulu. While a Fire Weather Watch or Red Flag Warning is not anticipated at this time, conditions may come close on Thursday or Friday afternoon.

Hawaii’s Marine Environment:  A strong high pressure system will build in north of the Hawaiian Islands over the next several days. Expect strong and gusty trade winds, possibly reaching gale force levels in the windier channels Thursday into the weekend. The Small Craft Advisory remains in effect for all coastal waters due to these strong trade winds and corresponding high seas. A Gale Watch may be needed for the second half of this week, for the windier waters and channels near Maui and the Big Island, in anticipation of even stronger wind speeds.

A large northwest (320-330) swell has started building into the Hawaiian region, and will reach advisory levels. This swell will rise quickly and peak well above advisory levels for exposed north and west facing shores, potentially nearing High Surf Warning thresholds, and then slowly decreasing, falling below advisory thresholds by Thursday night. A High Surf Advisory will start this morning at 6am HST, affecting north and west facing shores of Niihau, Kauai, Oahu, and Molokai, as well as north facing shores of Maui.

Rough and choppy surf along east facing shores will gradually become more elevated Thursday onward, as trade winds strengthen. Surf heights along east facing shores is expected to build to advisory levels Thursday into Friday, and then hold into the weekend.

Surf along south facing shores remains small, except for a small rise.

Peak monthly tides are forecast from November 14th to 18th. These high tides will combine with elevated seas due to strong trades and slowly fading northwest/north swells to exacerbate coastal inundation impacts, particularly for vulnerable locations during early morning high tides.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:   There are no active tropical cyclones

>>> Central and Western Caribbean Sea:

Invest 99L

A broad area of low pressure over the central Caribbean Sea continues to produce a large area of showers and thunderstorms. Environmental conditions are conducive for development, and a tropical depression is likely to form within the next couple of days while the system moves slowly westward into the western Caribbean Sea. Afterward, further development is likely while the disturbance meanders over the western Caribbean Sea through the weekend. The system is expected to turn slowly northwestward by early next week. Interests across the western and northwestern Caribbean Sea should monitor the progress of this system. Regardless of development, heavy rains are expected over Jamaica during the next day or so. An Air Force Hurricane Hunter aircraft is scheduled to investigate this system later today.

Interesting:  Fighting Microplastics for a Cleaner Future

Dr. Manish Shetty is working to break down microplastics to create usable fuel.

Microplastics, plastics smaller than 5 millimeters, are littered across the world, contributing to global warming, disrupting food chains, and harming ecosystems with toxic chemicals. This is why Dr. Manish Shetty is working to break down plastics before they can get into the environment.

Creating sustainable chemicals and developing better waste management will contribute to better sustainability. This research is part of figuring out how to make green hydrogen available for waste management using catalysts.

Shetty’s research uses solvents in low amounts that also act as hydrogen sources to break down a specific class of plastics called condensation polymers, which include polyethylene terephthalate (PET) bottles, packaging, textiles, and 3D printing.
