Hawaii’s MountainsHere’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 Wednesday comments:  I’m at home here in upper Kula, Maui, Hawaii

It’s mostly clear here in Maui County with calm winds at my place, and with a cool low of 50 degrees and the relative humidity is 76%

I played pickleball in Makawao, and then came back here to have lunch and work this afternoon. It got cloudy up here in Kula, and in many areas over and around Maui, and is relatively cooler than it has been lately.

Hawaii’s Broad Brush Weather Overview…as of Wednesday evening: High pressure ridging will influence island weather behavior the next several days. A weak low will approach Hawaii from the west today, and pass over the state Friday. Troughing ahead of this low will weaken our breezy trades and initiate more widespread showers Thursday and Friday. Any measurable rain will have low accumulation over the majority of the state. Weak troughing within a fairly dry air mass indicates stable enough conditions to support little to no precipitation through early June.

Weather Details for the Hawaiian Islands…as of Wednesday evening:  High stability remains firmly entrenched over the state. Breezy trades are delivering showers to windward and mountain sections of the islands, beneath the 8,000 foot trade inversion. No change in the large scale pattern is anticipated for the next several days as the islands reside under the subtropical jet stream, placing the region beneath a broad swath of large scale subsidence in maintenance of existing stability.

Sensible weather will be largely modulated by periodic fluctuations in the trades. The first such instance will be a gradual weakening of trades during the latter half of this week, in response to a rapidly weakening high migrating, weakening considerably as it does so. It is certainly plausible that trades are briefly lost altogether early next week, setting the stage for a period of land/sea breezes. Given the high stability environment in place, would expect little in the way of interior showers should that pattern develop. Otherwise, scattered showers will focus windward and mountain areas.

Marine Environmental Conditions…as of Wednesday evening: A surface ridge north of the state will maintain breezy to strong trade winds across the Hawaiian coastal waters, before a weakness developing in the ridge allows trade wind speeds to ease slightly during the latter part of the week into the weekend. A more significant weakening of the trade winds is likely this weekend into early next week, as a large North Pacific low pressure system far north of the islands breaks the ridge down even further.

A small, long-period northwest swell is peaking as it fills in down the island chain. North- and west-facing shores are experiencing near- to above-seasonal-average surf that will hold tonight, before gradually subsiding into the weekend.

A series of medium-period south swells will continue to bring small surf to south facing shores through Thursday. A more significant long-period south swell is expected to begin filling in Thursday night, and will likely bring above-advisory-level surf to south-facing shores through the weekend. This swell originated from a storm-force low that passed south and east of New Zealand over the weekend, generating seas of 35 to 40 feet or greater within Hawaii’s swell window.

Elevated surf along south-facing shores will likely continue into the first week of June, due to a continued active weather pattern near New Zealand, sending swells toward Hawaii. Rough surf along east-facing shores will gradually lower Thursday through the weekend as trade winds ease.

Interesting: 
Indonesia May Soon Lose Its Last Glaciers

Asia’s last tropical glaciers can be found near Puncak Jaya, Papua, the highest peak in Southeast Asia. But it is unlikely that they will survive until the end of this decade. Over the past 44 years, the peak has lost 97% of its ice and four of its glaciers. Its remaining two glaciers, Carstensz and the East Northwall Firn glacier, are expected to disappear by 2030, adding Indonesia (alongside Venezuela and Slovenia) to the list of countries that have lost all of their glaciers.

The rise in global temperatures has directly contributed to global glacier melt. For Indonesia’s glaciers, this has been punctuated by El Niño years. The El Niño Southern Oscillation (ENSO) is a global climate phenomenon characterized by weather patterns that alternate between La Niña and El Niño conditions that affect each region of the planet in different ways. In Indonesia, El Niño conditions have dramatically increased glacier melt.

“For Papua, it becomes dry and warm during El Niño, which means less snow at high elevations and more melting. Both can be a death knell, especially to a small glacier,” said Mike Kaplan, a geologist at the Lamont-Doherty Earth Observatory, which is part of the Columbia Climate School. He studies the history of glaciers, climates and past landscapes. During the recent El Niño event between 2015 and 2016, Indonesia’s glaciers took a big hit.
