Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the (~10,023 feet high) Haleakala Crater 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.

Glenn’s Aloha Friday comments:  I’m with my friend Bob here at our vacation rental at Sea Ranch, Sonoma County, CA on a working vacation.

447am HST, it’s cloudy with light rain and gusty this morning in coastal Sonoma County, the low temperature was 55.5 degrees.

130pm HST, a rainy morning has led into a partly cloudy afternoon, with a few showers. Looking out over the ocean now, I see several thunderstorm cells brewing. I’m hoping there will be some lightning and claps of thunder before too long.

611pm HST, we just got back from a dark walk outside. The first time we tried to have a walk after dinner we got pushed back inside by a quickly passing shower. The temperature has dropped in the wake of this first significant cold front of the rainy season. Here at our place in Sea Ranch the temperature is 50.9 degrees.

Hawaii’s Weather Highlights…as of Friday evening: A weakening high pressure ridge north of the Hawaiian Islands will keep trade wind speeds on the decreasing side lasting into Saturday, then ridge and wind speeds strengthen Saturday afternoon into early next week.

Passing showers are possible over windward and mountain areas during this time, mainly during the overnight to early morning hours. The next best chance for statewide rainfall may develop Monday into Tuesday of next week, as the cloud remnants from an old cold front drift across the islands on the trade winds.

Weather Narrative…as of Friday evening: Radar shows isolated trade showers moving into most windward areas. A few are still making it over to leeward areas, but rainfall amounts have been very light (just a few hundredths of an inch or so). Winds were averaging 10 to 20 mph, with the normal windy locations gusting near 30 mph. Weak upper level ridging will remain in place near Hawaii through the weekend.

At the surface, a high pressure system will move from our northwest to our northeast. Monday, an upper level low will approach from the northwest. At the same time, but unrelated, a band of moisture associated with an old front will move across the state from the northeast. This should lead to a brief increase in showers, but no significant rainfall is expected. The best guess on timing for this band, according to the latest guidance, is Monday evening.

The upper level low will continue to weaken as it moves very close to Hawaii Wednesday into Thursday. With minimal cold air aloft, it is expected to result in a slight increase in instability, perhaps leading to a small increase in both the coverage and intensity of showers. A new ridge aloft is forecast to move in from the west late next week. Throughout the entire period, trades will continue.

Fire Weather: Fire weather conditions will remain below critical, limited by wind speeds for most areas, and by higher minimum humidity levels for the higher elevation zones that reach wind thresholds. Wind speeds will increase into the moderate to breezy levels by late Saturday, lasting into early next week. Temperature inversion heights near Maui and the Big Island will range from 6,500 to 7,500 feet elevation through Saturday.

Marine Conditions…as of Friday evening: A high pressure system north of Hawaii will slowly weaken, allowing trade winds to slightly decrease. A Small Craft Advisory (SCA) is in effect for the typical windy waters near Maui County and the Big Island. By Sunday evening, a new high pressure will build north of the islands and restrengthen trade winds, likely leading to an expansion of the SCA to include additional waters. Next week will likely see continuing fresh to strong trades with some minor fluctuations each day.

A moderate to large north-northwest swell is also expected to fill in early Sunday morning and elevate coastal waters seas. A moderate, north-northwest swell will continue to decline into the weekend, allowing surf to become moderate to small and then small. A new small, north-northwest swell will support continued small surf before the arrival of a more significant north swell. This moderate, long- period north swell arriving Saturday night may bring surf to advisory levels on Sunday for north and west- facing shores. Surf to at least moderate levels will last into Monday before the swell really begins to fade on Tuesday. A small to moderate northwest swell is then possible by next weekend.

Surf along east-facing shores will remain rough and choppy due to the strong trade winds, then may decrease slightly as trades ease early this weekend. Surf will increase again Sunday into early next week as trades restrengthen.

South shore surf will stay tiny to small for the next few days, then a small long period swell could boost surf heights towards the end of next week.

Arctic Wildlife Research Suffers as Geopolitical Competition Grows

Decades ago, one of the world’s largest subpopulations of nesting eider ducks spent its summers on tiny Mitivik Island, near the mouth of Hudson Bay. But as concern grew, in the 1990s, over their steep decline globally, the Canadian government set up a rudimentary research station near the island in the hopes of forestalling a collapse.

The modest investment paid enormous dividends over the next 30 years as Inuit partners from nearby Southampton Island, who hunt common and king eiders for food and feathers, worked with scientists from all over the world to solve the mystery of where the birds spent their winters and the causes of, and remedy for, their initial decline. In the field for months at a time, researchers also gained critical insights into how climate change, disease, diminishing sea ice, and polar bears were affecting bird populations.

As remarkably successful as the pioneering research station was, though, Canada’s Environment and Climate Change department quietly shut it down in 2024. By then, the number of nesting eiders had crashed again, from a high of 8,000 pairs to just a few hundred.
