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. 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 48.5 degrees.

143pm, it’s mostly cloudy up here in Kula, with sunny to partly sunny conditions done near the beaches. My temperature here at home is 67.8 degrees, with very light winds.

My high temperature today here in Kula was 72 degrees

Weather Wit of the day:  Sunburn – When ignorance is blister

 

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

A cold front will approach from the northwest Wednesday and Thursday, shifting winds more southerly and bringing an increase in showers, particularly over the western end of the state. The front should lift northward as a warm front on Friday, with some lingering moisture keeping some scattered shower activity in place over the western islands.

A return to mostly dry and stable conditions are then forecast to follow next Saturday

Hawaii’s Weather Details:  Weather maps show a high far east-northeast of Honolulu, with a ridge extending southwestward to a location near or just north of Kauai. Land breezes prevail across much of the state, with un-sheltered sections of Maui and the Big Island seeing light to moderate east-southeast trade winds.

Infrared satellite imagery shows mostly clear to partly cloudy conditions. Radar imagery shows a few showers moving into windward and southeast facing slopes of Maui and the Big Island, with little if any shower activity elsewhere.

The ridge of high pressure near Kauai will remain nearly stationary, keeping land and sea breezes dominant over the western islands, while light to moderate trades hold over the eastern end of the state. A new high building north of the area is expected to bring a brief return of light to moderate trades statewide on Sunday, before the approach of a cold front eases the trades again Monday.

Light to moderate trades may briefly fill back in Tuesday, followed by a transition to more southerly flow at light to moderate speeds Wednesday and Thursday, in advance of another approaching cold front. This front is forecast to lift back northward as a warm front late next week, allowing a return of light to moderate east to southeast winds across the state.

Meanwhile, mostly dry and stable conditions are expected through Tuesday. There will still be a few showers moving into windward slopes and coasts each night, with a few daytime heating showers possible over the island interiors each afternoon. Rainfall amounts should remain light however, with low and mid level ridging keeping inversion heights suppressed.

As winds turn southerly in advance of another front Wednesday and Thursday, the atmosphere should moisten up and inversion heights should rise, bringing an increase in showers, particularly over the western end of the state. A land and sea breeze pattern featuring windward showers at night and interior showers during the day may return for the end of the upcoming work week.

Hawaii’s Marine Environment:  High pressure remains over the northeastern Pacific, with a ridge extending southwest to just north of the islands. The ridge will keep light and variable winds in place for the western end of the state, and light to moderate southeasterly winds for the eastern part of the state through tonight.

Light to moderate easterly trade wind flow will then return Sunday into Monday, as high pressure briefly rebuilds north of the state. A cold front could then pass north of the islands and weaken the wind speeds again Tuesday onward.

Current west-northwest swell will hold before increasing tonight into Sunday. Peak surf heights are expected to exceed advisory levels and could potentially reach warning levels along north and west facing shores Sunday. Another similarly- sized northwest swell is expected to build in Tuesday night and linger through Wednesday.

Small surf is expected along south and east facing shores.

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.”
