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 Aloha Friday 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 clear here in upper Kula early this morning, while the low temperature was 50 degrees.

426pm, partly cloudy with a temperature of 67 degrees here at my place. I drove up the mountain this morning and went to my usual skateboarding section of road, up around 5,500 feet elevation…where I had several good runs.

632pm, it’s partly to mostly cloudy with a light shower here in upper Kula right around sunset. My high temperature was 70.5 degrees.

Weather Wit of the day:  Sunburn – Getting more than you basked for

 

Hawaii’s Broad Brush Weather Overview:  Light winds and mostly dry conditions will prevail through early next week, with a few showers possible along windward slopes and coasts at night and over the island interiors each afternoon.

A series of cold fronts will approach from the northwest next week, bringing an increase in showers, particularly over the western end of the state around the middle of the week, and again towards the end of the work week.

Hawaii’s Weather Details:  Radar and satellite imagery show a slight increase in clouds and showers across the eastern end of the state, as a plume of moisture moves in on the trades. Over the western half of the state, clouds and isolated showers are favoring windward and mountain areas, as land breezes have helped to at least partially clear leeward areas.

A surface ridge centered well to the northeast of the state will maintain light to locally moderate trades, that will allow for clouds and showers to generally focus over windward areas, then transition to focus over leeward and interior areas with afternoon sea breeze development. However, only light rainfall amounts are expected with these brief passing showers, due to limited moisture and increasing stability as ridging builds in from the west.

A progressive pattern to our north will bring a series of fronts to our doorstep over the next several days, periodically disrupting the trades, and bringing an increase in showers to the western end of the state. Between each front, the surface ridge to the northeast of the state will try to reestablish itself, but will have a hard time doing so, as each front will be followed closely by its successor.

The second front will approach early next week and may increase rain chances over the western end of the state Tuesday night into Wednesday, as the frontal boundary dissipates near Kauai. However, model guidance shows both the boundary and its moisture field mostly dissipating before reaching the state, so don’t expect much of an increase in shower activity with this front either.

Then ahead of the third front, winds will turn southerly Wednesday and Thursday, allowing the boundary layer to moisten up and inversion heights to rise, bringing a slight increase in shower activity, particularly over the western end of the state. The third front looks to approach towards the end of the work week, potentially bringing another, slightly more significant rise in rain chances for the western end of the state Thursday night into Friday.

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

Hawaii’s Marine Environment:  High pressure over the northeast Pacific will hold through the weekend. A ridge extending from the high and passing just north of Hawaii will drive generate east winds. The ridge will shift south causing low level winds to weaken and shift to the east-southeast tonight. Light trade wind flow will then persist through the remainder of the weekend and into next week.

The current west-northwest swell will continue its gradual decline. The next significant northwest swell is due late Saturday into early next week, with peak surf heights likely reaching warning levels along north and west facing shores. Yet another similar sized northwest swell is expected to build in Tuesday night and linger through Wednesday night.

Small surf is expected along east facing shores over the next week, as trade winds remain light. Surf along south facing shores should see a small boost as a small south swell fills in on Friday and Saturday.

Interesting:  The Rising Tide of Sand Mining: A Growing Threat to Marine Life

In the delicate balancing act between human development and protecting the fragile natural world, sand is weighing down the scales on the human side.

A group of international scientists in this week’s journal One Earth are calling for balancing those scales to better identify the significant damage sand extraction across the world heaps upon marine biodiversity. The first step: acknowledging sand and gravel (discussed as sand in this publication) – the world’s most extracted solid materials by mass – are a threat hiding in plain sight.

“Sand is a critical resource that shapes the built and natural worlds,” said senior author Jianguo “Jack” Liu, Michigan State University Rachel Carson Chair in Sustainability. “Extracting sand is a complex global challenge. Systems approaches such as the metacoupling framework are essential to untangle the complexity. They can help reveal the hidden cascading impacts not only on the sand extraction sites but also other places such as sand transport routes and sites using sand for construction.”
