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 Tuesday 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 my low temperature was a very chilly 47 degrees.

Weather Wit of the day:  Winter – The days of shivery

 

Hawaii’s Broad Brush Weather Overview:  Light to occasionally moderate east to southeasterly winds are expected to persist through the remainder of the week into the weekend, favorable for light showers across windward areas during the overnight hours, and leeward and interior areas during the afternoon hours associated with seas breeze development.

Overall shower activity will be limited. An upper-level low will make its way to the vicinity of the islands early next week, though confidence remains low at this time with regards to the strength and positioning of the low.

Hawaii’s Weather Details:   Land breezes have developed within a light to moderate east to southeasterly background flow, with shower activity easing through the early morning hours, as an upper-level ridge builds east of the islands, increasing overall stability while propagating drier air westward. Meanwhile, a stationary front just north of Kauai will continue to linger and dissipate.

Southeasterly winds will strengthen slightly over the next few days as the pressure gradient between the broad upper-level high to the far northeast of the islands, and an incoming frontal passage from the west as a part of a more progressive pattern. While some showers will still be carried into windward areas on the east to southeast winds, the lighter flow will allow sea breezes to prompt cloud buildups and a few showers to leeward and interior areas each afternoon, and land breezes to help clear out leeward and interior areas overnight.

Toward the latter end of the week and into the weekend, a light trade wind pattern returns, and with it, light shower activity to the windward areas of most islands, and maintaining this pattern throughout the weekend. Thereafter, the confidence decreases as the latest model guidance diverges as the strength and positioning of a forecast low west-northwest of the islands. Evolution of this low may play a factor in local wind speeds and direction, however, currently no major impacts are expected at this time.

Hawaii’s Marine Environment:  A dissipating stationary front over the far north offshore waters, along with a weak surface high to the east of the islands, will maintain a fairly slack pressure gradient across our local waters. This will result in gentle to moderate east to southeast winds through tonight.

A developing low far northwest of the islands will pull further back to the northwest. As this occurs, a front extending east of the low will generally veer gentle easterlies more southeasterly through the Wednesday. Surface high pressure positioned northeast of the islands will remain the main driver of primarily light to gentle east-southeast breezes the remainder of the week.

The moderate size, medium period northwest (320-330 degree) swell that peaked yesterday, will be gradually falling lowering. The High Surf Advisory remains in effect for the smaller island north-facing and west-facing shores (except Maui) to account for this slow declining swell. A small, medium period north (350-010 degree) swell is expected to arrive on the heels of this fading northwest-north swell Thursday. This north swell is forecast to peak Friday then ease over the weekend.

South shore surf will remain seasonably small the next couple of days. A small swell arriving from a series of gale lows passing south of New Zealand will arrive near the end of the week. This additional foot on top of southern background long period swell, will provide a small bump to southern shore surf Thursday and/or Friday.

Interesting:  Snapshot of Antarctica’s Past Helps Predict Future Climate

In the first study to consider the long-term evolution of the rivers that flow beneath glaciers, researchers have new insights into the future of Antarctica’s melting ice that may change the way climate scientists predict the effects of a warming planet.

Researchers from the University of Waterloo’s Faculty of Environment led the project that studied Aurora Subglacial Basin and modeled its subglacial hydrology —the flow of water at the base of the ice. They compared drainage systems at various times ranging from 34 million years ago to 75 years from now.

They found that these rivers are dynamic, changing from one period to another. Aurora Subglacial Basin is in East Antarctica and is grounded below sea level, a particularly unstable configuration that could lead to rapid and irreversible retreat, and an increase of four meters in the global ocean level if all the ice in the region melted.
