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 Sunday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s partly cloudy with thick volcanic haze here in upper Kula early this morning, while my low temperature was 50 degrees.

420pm, a mix of low and high level clouds, making a partly to mostly cloudy afternoon, along with thick volcanic haze.

620pm, cloudy, voggy, with a light shower here in upper Kula…63.6 degrees at my place.

Weather Wit of the day:  Taxi Driver – A meterologist

 

Hawaii’s Broad Brush Weather Overview:  Rain chances will steadily increase through the week, as southerly winds associated with a cold front and upper disturbance draw moisture northward into the islands. This front may reach the islands around Thursday, potentially leading to more widespread rainfall into next weekend.

Hawaii’s Weather Details:  A nearly stationary, deep low pressure system is centered around 1200 miles northwest of Kauai. A jet stream along the eastern flank of this system will bring cirrus clouds over much of the state, particularly the western half into Monday. At the surface, a weak high is located about 2000 miles to the east, with a long ridge axis that passes just north of Hawaii. Gentle southeast winds will be the result of the ridge to the east tonight with land breezes decreasing low clouds over the island interiors tonight. Vog will carry up from the Big Island to the smaller islands over the next several days.

The low pressure system and associated cold front will begin to move closer to the islands Monday and Tuesday. Southerly winds will strengthen and bring increased moisture initially over the western end of the state as early as tonight and over the next few days. Clouds and showers will focus over leeward and south facing slopes (southeast for Big Island).

Winds will taper off and veer southwesterly as the front nears the western end of the state allowing land and sea breezes to take over again. The front may reach Kauai around Thursday and begin to stall and weaken into Friday with trade winds filling in over the frontal boundary, potentially leading to more widespread rainfall into next weekend.

Hawaii’s Marine Environment:  Light and variable winds will hold over the western islands, while light to moderate east-southeasterly trades prevail over the eastern end of the state. A storm system to the distant northwest, will strengthen winds and shift them around to the southeast and south Monday through Tuesday. Localized terrain enhancement around the Big Island could result in advisory level winds during this time. The winds will gradually ease Wednesday and Thursday as a front approaches from the northwest, with moderate to fresh northeast trades filling in behind the front for the end of the week.

A series of small overlapping north-northeast swells will keep some surf in place along exposed north and east facing shores through mid-week. A small west-northwest swell will bring some small surf to exposed north and west facing Tuesday through Thursday. A more significant north-northwest swell appears to arrive late in the week, potentially bringing warning level surf to north and west facing shores next weekend.

Surf along south facing shores will remain up, then return back to seasonable levels Monday through late next week.

Interesting:  Making Sturdy, Semi-transparent Wood With Cheap, Natural Materials

Can you imagine a smartphone with a wooden touchscreen? Or a house with wooden windows? Probably not — unless you’ve heard of transparent wood. Made by modifying wood’s natural structure, this material has been proposed as a sturdy, eco-friendly plastic alternative. But wood’s biodegradability is often sacrificed in the process. Researchers are hoping to change that by creating transparent woods from almost entirely natural materials and making them electrically conductive.

The researchers will present their results at the spring meeting of the American Chemical Society (ACS). ACS Spring 2025 is being held March 23-27; it features about 12,000 presentations on a range of science topics.

“In the modern day, plastic is everywhere, including our devices that we carry around. And it’s a problem when we reach the end of that device’s life. It’s not biodegradable,” explains Bharat Baruah, a professor of chemistry at Kennesaw State University and the presenter of this research. “So, I asked, what if we can create something that’s natural and biodegradable instead?”
