Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. 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

Good day everyone, I hope you have a great Sunday wherever you happen to be spending it.

739am, it’s mostly cloudy with a few sprinkles this morning here in Kula, with a low temperature of 59.5 degrees at my place.

824am, still cloudy with a few sprinkles, and the temperature here at my Kula weather tower has warmed to 66.7 degrees. These clouds are the middle level variety, leaving the tops of the mountains showing up clearly. It appears that the clouds are trying to break up a little, and I can even see a few thin strips of blue skies off in the distance.

 

Hawaii’s Broad Brush Weather Overview:  A late season kona will continue to move north and weaken as a ridge of high pressure over the state shift north today and Monday. Expect a gradual drying trend and the return of easterly trade winds Monday into the second half of the week.

Hawaii’s Weather Details:  The Flood Watch for Kauai has been cancelled. The heaviest rainfall activity has moved north of Kauai and expected to continue to move north and dissipate. A few small moderate to heavy showers did move through the area overnight, producing rainfall totals a little over a quarter of an inch. Oahu received a little more rainfall than Kauai early on in the night but then the light to moderate showers moved over Maui County.

Latest satellite imagery shows a mix of high and low clouds across the state, which is going to make for a cloudy start to the morning. Radar imagery shows mid to high reflectivity returns, indicating some expansive light to locally moderate rain over much of the state. Again, rainfall totals so far have remained modest and conditions are anticipated to clear from east to west as the day progress.

Gentle to locally breezy east to southeast winds are expected to persist. Lighter and more variable winds over the western half the state will allow for land seas breeze pattern. The axis of above normal moisture is also expected to shift northwest, and an upper level trough will exit to the east during this time. Expect more stabilizing trends over the western half of the state today. A slight chance of thunderstorms is still possible for the upper slopes of the Big Island this afternoon as the upper level trough exits east.

Lingering moisture and some upper level instability from a couple more low pressure troughs may enhance trade wind showers Tuesday into the second half of the week, as the ridge settles north of the state. A more typical trade wind pattern may return late in the week.

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

Hawaii’s Marine Environment:  Locally strong east-southeast winds will persist through Monday, before transitioning to easterly trades Tuesday through next weekend. A Small Craft Advisory (SCA) remains in effect for the windier waters around Maui County and the Big Island. This SCA may need to be extended in time.

A pair of overlapping south swells will keep south shore surf near low end advisory levels. The swell will hold near or just below advisory levels tonight and Monday, then gradually lower through the middle of the week. South shore surf will fall back below the summertime average Thursday through next weekend, with only small south and south-southwest swells rolling through.

The current very small northwest swell will gradually lower through Monday, with north shore surf going flat Tuesday through next weekend.

Surf along east facing shores will remain well below average through early in the new week. An upward trend is expected Tuesday through next weekend, as trade winds strengthen over and upstream of the islands.

Interesting:  Copper Can’t Be Mined Fast Enough to Electrify the US

Copper cannot be mined quickly enough to keep up with current U.S. policy guidelines to transition the country’s electricity and vehicle infrastructure to renewable energy, according to a University of Michigan study.

The Inflation Reduction Act, signed into law in 2022, calls for 100% of cars manufactured to be electric vehicles by 2035. But an electric vehicle requires three to five times as much copper as an internal combustion engine vehicle—not to mention the copper required for upgrades to the electric grid.

“A normal Honda Accord needs about 40 pounds of copper. The same battery electric Honda Accord needs almost 200 pounds of copper. Onshore wind turbines require about 10 tons of copper, and in offshore wind turbines, that amount can more than double,” said Adam Simon, U-M professor of earth and environmental studies. “We show in the paper that the amount of copper needed is essentially impossible for mining companies to produce.”

The study examined 120 years of global data from copper mining companies, and calculated how much copper the U.S. electricity infrastructure and fleet of cars would need to upgrade to renewable energy. It found that renewable energy’s copper needs would outstrip what copper mines can produce at the current rate. The study, led by Simon and Cornell University researcher Lawrence Cathles, was published by the International Energy Forum and discussed in a webinar, “Copper mining and vehicle electrification.”
