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 Saturday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s mostly clear here in Maui County this morning, with clouds along the windward side. The low temperature here at my place was 51.5 degrees.

The clouds have closed in over Maui, and across much of the state this afternoon. I played 4 good games of Pickleball in Haiku this morning, and on the way home stopped off in Paia for my weekly shopping at Mana Foods.

I’m back home now, and it’s cloudy, although not raining, like it is in Makawao at the time of this writing.

Weather Wit of the day:  Whitecaps – Luggage handlers on a cruise ship

 

Hawaii’s Broad Brush Weather Overview:  Breezy easterly trade winds will persist today, with showers favoring windward and mountain areas. The trades will briefly weaken and shift out of the east-southeast tonight through Sunday, as a broad surface trough develops far northwest of the islands.

Increasing moisture may lead to enhanced shower activity Sunday into Monday, particularly over the western end of the state. Breezy easterly trades and drier conditions are expected to return during the first half of next week, as the trough weakens and shifts away from the state.

Hawaii’s Weather Details:  A wet and breezy trade wind pattern remains in place, with showers favoring windward and mountain areas. Some of these showers are managing to reach the typically drier leeward areas over the smaller islands, due to a weak mid-level trough, an elevated trade wind inversion positioned between 8,000 and 9,000 ft, and pockets of moisture moving through.

Peak rainfall accumulations around the state ranged from a quarter to just under half of an inch. This showery pattern is expected to persist through the morning, gradually improving later in the day as the moisture shifts westward.

The development of a broad surface trough far northwest of the state will lead to a weakening and veering of the trades out of the east-southeast late tonight through the second half of the weekend. This evolving pattern will draw increased moisture northward into the area, enhancing instability and supporting greater cloud and shower coverage – particularly over the western end of the state, where the instability will be more pronounced.

As winds ease on Sunday, showers will become more focused over interior and leeward areas of Kauai and Oahu during the afternoon, with a few potentially becoming briefly heavy. This unsettled pattern will persist into Sunday night and early Monday, with land breezes developing across the western islands, and showers favoring windward and coastal locations – again with the potential for locally heavy downpours. Meanwhile, more stable conditions and a continuation of typical easterly trades are expected to hold across the eastern end of the state.

A return to breezy and more stable trade wind conditions is expected by Monday night into the first half of next week, as drier air filters in from the east. This will result in a more typical trade wind pattern, with showers favoring windward and mountain areas, and generally dry conditions prevailing elsewhere.

Hawaii’s Marine Environment:  Fresh to strong easterly trades associated with a surface ridge to the north will continue, with the strongest winds over the typically windier channels and waters around Maui County and the Big Island. Forecast guidance suggests the ridge will briefly weaken through the latter half of the weekend, as a broad surface trough develops far northwest of the area.

This will lead to the trades veering out of the east-southeast to southeast by Sunday, with lighter and more southeast winds over the western end of the state, and fresh east-southeast winds continuing over the eastern end. The winds will shift back out of the east and strengthen early next week, as the trough weakens and tracks away from the area.

Surf along exposed north and west-facing shores will climb well above average for this time of year as a fresh, medium-period north-northwest (330-340 degrees) swell builds down the island chain. Swell observations at the offshore buoys surged above predicted levels overnight, which will lead to surf heights nearing advisory levels as it fills in. This north-northwest source will peak, then steadily lower tonight through early next week, with heights returning to seasonal levels.

Surf along exposed south-facing shores will continue to see a mix of long-period background south-southwest and shorter-period southeast swells through the middle of next week. Another long-period south-southwest swell is possible late next week, due to a system passing through our swell window near New Zealand. If this materializes, surf could climb to above average levels by next weekend.

Surf along east-facing shores will remain small and choppy through the weekend, then gradually build through the upcoming week, due to a return of fresh to strong trades locally and upstream across the northeastern Pacific.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclones

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific:   There are no active tropical cyclones

Offshore of Central America and Southern Mexico

>>> An area of low pressure is likely to form by the middle part of next week offshore of the coasts of Central America and southern Mexico.

Environmental conditions appear favorable for some development of this system thereafter, and a tropical depression could form late next week while it moves generally westward to west-northwestward at around 5 to 10 mph.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…40 percent

Interesting:  Playing With Fire: Harnessing Lava To Build Sustainable Cities

When it comes to carbon emissions, there’s no bigger foe than the building and construction sectors, which contribute at least a third of global greenhouse gases.

A new project suggests a novel solution, albeit one still quite theoretical: Lava.

Over the past several months, the Volcanology Group at Lamont-Doherty Earth Observatory, led by Lamont research professor Einat Lev, had the opportunity to collaborate with a team of architects selected to exhibit at the Venice Biennale. (Lamont is part of Columbia University’s Climate School.) The project, “Lavaforming,” conceived by s.ap architects, imagines a future in which lava flows—like those regularly occurring on Iceland’s Reykjanes Peninsula—can be harnessed and shaped into sustainable building materials for entire cities.
