Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.

Aloha Paragraphs



Weak cold front well to the northwest…with more high
cirrus clouds approaching to our west and southwest

Clear to partly cloudy…another area of showers taking aim on our islands – mostly
over the windward sides tonight / bright white cirrus to our southeast
and southwest – here’s the looping version of the satellite photo above

Showers are falling over the nearby ocean…arriving
along the windward sides on the trade wind flow –
some locally quite generous

Here’s the looping radar image for the Hawaiian Islands

Small Craft Advisory…strong trade winds across coastal
and channel waters around Maui County and the Big Island

~~~ Hawaii Weather Narrative ~~~

Trade winds will continue…with fairly minor day to day variations into the new week. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find a large, near 1029 millibar high pressure system located to the north-northeast of the state. As a result of this high pressure feature, and low pressure well to the south in the deeper tropics, our winds will continue to come in from the trade wind direction well into the future. The latest models are now showing the trade winds finally backing-off during the second half of the new week ahead, likely bringing sultry weather for a few days then…with returning trade winds next weekend.

A modest cloud band will push through the state again tonight…bringing showers to mostly Maui and the Big Island. The windward sides will see these showers arriving…as an area of clouds gets carried through our area on the trade winds. There will be a few showers carried over into the leeward sides on the smaller islands locally…in addition to upcountry afternoon showers again this weekend. These interior showers will be most prevalent on the Big Island…and possibly the leeward slopes on Maui. As we move through the weekend into the first half of the new week, a fairly normal trade wind weather pattern will prevail. I’ll be back with more updates on all of the above, I hope you have a great Saturday night wherever you’re spending it! Aloha for now…Glenn.

Here on Maui...early Saturday morning before sunrise, skies are mostly clear, with just the usual clouds over the West Maui Mountains. The windward sides clear to partly cloudy. The air temperature here in Kula at 605am was 54.3 degrees, while the summit of the Haleakala Crater was showing a 36 degree temperature. At the same time, it was a warmer 73 at the Kahului airport, with a 70 degree reading out in Hana. It’s a beautiful morning here on Maui, just lovely!

It’s now around 530pm, under clear to partly cloudy skies. It was a really nice day, with mostly sunny skies in general, and just a few cloudy periods. As I was mentioning above, there’s another cloud band that will be pushed onto our windward sides tonight, although like last night, it may not amount to very much more than normal. This evening I’m heading down to Spreckelsville with my friends Jeff and Svetlana, to some friends house…right on the beach! There’s a big salt water pool, with the water temperature a very warm 87 degrees! I may even get to sneak into the nearby ocean for a dip too, besides having dinner and apparently there will be a dance party. Aloha, Glenn

Friday Evening Film – This is a film that many of you will roll your eyes over, and who could blame you? However, I’m drawn to these action films…almost like a bee to honey I’m afraid. I guess one could say that it’s a guy thing. At any rate, this one is called Furious 7, starring Vin Diesel, the late Paul Walker, Tony Jaa, Jason Statham, Michelle Rodriguez, Nathalie Emmanuel, Jordana Brewster, Dwayne “The Rock” Johnson, and Elsa Pataky…among many others. The synopsis: Continuing the global exploits in the unstoppable franchise built on speed, Vin Diesel, Paul Walker and Dwayne Johnson lead the returning cast of Fast & Furious 7.

The critics are being pretty generous to this film, and I can see why after sitting through it. It was another of those cartoon type films, with outrageous special effects peppered throughout. It was the kind of film that you just have to cinch your seat belt tight, and hang on for dear life. The director throw out the concept of gravity right from the get go, and the film just kept free falling from there. Despite the fact that it was billed as an action thriller, it could have just as easily been referred to as an action comedy. The essence of this film can be distilled into its strong camaraderie, its intensity, and yes even emotion. I liked this long 2 hour 20 minute speed ride through the absurd! As for a grade, and considering what it was, I’d give it a B+. Here’s the trailer for this film, just in case you’re interested.

Interesting: New Research Identifies First Warm-Blooded Fish – New research by NOAA Fisheries has revealed the opah, or moonfish, as the first fully warm-blooded fish that circulates heated blood throughout its body much like mammals and birds, giving it a competitive advantage in the cold ocean depths.

The silvery fish, roughly the size of a large automobile tire, is known from oceans around the world and dwells hundreds of feet beneath the surface in chilly, dimly lit waters. It swims by rapidly flapping its large, red pectoral fins like wings through the water.

Fish that typically inhabit such cold depths tend to be slow and sluggish, conserving energy by ambushing prey instead of chasing it. But the opah’s constant flapping of its fins heats its body, speeding its metabolism, movement and reaction times, scientists report today in the journal Science.

That warm-blooded advantage turns the opah into a high-performance predator that swims faster, reacts more quickly and sees more sharply, said fisheries biologist Nicholas Wegner of NOAA Fisheries’ Southwest Fisheries Science Center in La Jolla, Calif., lead author of the new paper.

“Before this discovery I was under the impression this was a slow-moving fish, like most other fish in cold environments,” Wegner said. “But because it can warm its body, it turns out to be a very active predator that chases down agile prey like squid and can migrate long distances.”

Gills show unusual design

Wegner realized the opah was unusual when a coauthor of the study, biologist Owyn Snodgrass, collected a sample of its gill tissue. Wegner recognized an unusual design: Blood vessels that carry warm blood into the fish’s gills wind around those carrying cold blood back to the body core after absorbing oxygen from water.

The design is known in engineering as “counter-current heat exchange.” In opah it means that warm blood leaving the body core helps heat up cold blood returning from the respiratory surface of the gills where it absorbs oxygen. Resembling a car radiator, it’s a natural adaptation that conserves heat. The unique location of the heat exchange within the gills allows nearly the fish’s entire body to maintain an elevated temperature, known as endothermy, even in the chilly depths.

While mammals and birds typically maintain much warmer body temperatures, the opah is the first fish found to keep its whole body warmer than the environment.
