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 Thursday comments:  My good friend Bob Earle and I are here at Sea Ranch, CA.

It’s cloudy this morning here at the CA coast, with rain and strong gusty winds. The low temperature was 58 degrees.

The storm clouds from last night here on the coast seem to be clearing up, although it looks like it could cloud up again. There were two small trees that got knocked over (on this property) by the windy storm last night, which Bob and I estimate reached 50-60 mph at their peak.

The sun came out for a time this afternoon, although now the low clouds are coming onshore from the ocean. Speaking of which, Bob and I had a nice walk down to a nearby beach, where as usual, we had it to ourselves. The storm last night kicked up some large and very rough waves. I love to walk out as far as I can as the waves recede, and then sometimes have to run as fast as I can as the next wave tries to catch me.

The rain finally arrived, again, after last nights onslaught of wind and rain!

Hawaii’s Broad Brush Weather Overview:  Strong trades into Friday as frequent showers persist over Windward Maui and Big Island. A drying trend is anticipated Friday night into the weekend as locally breezy trades prevail.

Hawaii’s Weather Details: Strong ridge of high pressure remains parked to the northeast. The gradient around this high will support continued strong trades into Friday. Sustained winds and a few gusts have reached the Wind Advisory threshold in the windiest locales and favored downslope areas of the Big Island and Maui County.

Embedded within the background of strong trades is a band of remnant frontal moisture taking aim directly on Windward Big Island. 24 hour rainfall amounts have averaged 1-3″ in this area, and that includes the drought-stricken Hamakua Coast of the Big Island, where multiple stations reported in excess of 2″ with a peak observation of 3.15″ upslope of Laupahoehoe.

The latest satellite trends and model guidance suggest this band of showers will not be budging during the next 24 hours, though subtle veering of wind to a more easterly direction than the current ENE Friday, suggests a gradual progression away from the Hamakua District, and an increasing focus on the South Hilo and Puna Districts. Overall, seems prudent to anticipate at least an additional 1-3″ over the same areas by tomorrow, bringing 48-hour totals into the 2-6″ range. The same can be said for windward portions of Haleakala.

Elsewhere over the smaller islands, visible satellite indicates considerably less organized and shallower clouds. Nonetheless, showers have persistently regenerated over the terrain, particularly over the Koolau Range of Oahu. This is probably attributable to diminished stability, owing to enhanced moisture trapped beneath the inversion. Little penetration of showers into central Oahu has been noted, but that will likely change as showers deepen during the night.

A drying trend commences late Friday into the weekend, as a band of particularly dry mid-level air advances into the area. Inversion heights likely crash down to 5,000 feet or lower by early Saturday,  bringing an end to meaningful rainfall across the area. Trades weaken during this time beginning as early as Friday, which will still be quite gusty but not likely to be supportive of extending the Wind Advisory. Isolated 50 mph gusts are not out of the question in the very windiest locales.

The next round of upper troughing commences during the first half of next week, bringing potential for mid-week frontal passage and a period of wetter weather.

Fire weather:  Breezy to windy trades will continue, becoming moderate to breezy before the weekend. Low-level moisture embedded in the trades should help to maintain relative humidity above critical fire weather thresholds. Temperature inversion heights near the Big Island and Maui will range from 9,000 to 10,000 feet for the time being.

Hawaii’s Marine Environment:  A strong surface high north-northeast of the islands, is driving fresh to locally gale force trade winds across Hawaiian waters. The high will sag southeast and weaken slightly, which will shift winds to a more easterly direction. The Gale Warning has been extended through this afternoon for the Alenuihaha Channel, as wind speeds are still expected to maintain their strength. Elsewhere, a Small Craft Advisory (SCA) remains in effect for a combination of winds and seas. Some zones may drop out of the SCA tonight as winds and seas ease for leeward zones around Kauai and Oahu.

The high pressure will meander northeast of the state near 30N tonight into early next week while gradually weakening. Trade winds are expected to ease to moderate to locally strong speeds overnight and Friday then possibly to more gentle to fresh speeds over the weekend. A front approaching from the northwest early next week could veer the winds out of the southeast with winds weakening more light to moderate levels.

The current short period northeasterly (030 to 050 degree) swell will gradually decline through Friday. Offshore buoy 51000 is still showing plenty of energy that may likely keep surf elevated along east facing shores. Rough, choppy east shore surf will continue to gradually decline through the weekend as local and upstream trade winds speeds ease. Meanwhile, a small to moderate long period northwest swell that has peaked will gradually decline. Another small, long period, northwest swell will fill in over the weekend, which should provide a small increase in surf along north and west facing shores.

A small, long period, south swell that has peaked will slowly fade through Friday. Small background south and southwest swells will fill in over the weekend, keeping surf along south from going flat.

Interesting:  The Next Frontier In Clean Flight? Jet Fuel From City Waste

Aviation currently contributes about 2.5% of total global carbon emissions, and with air travel demand expected to double by 2040, cutting those emissions has become a pressing priority. One path forward is sustainable aviation fuel, a low-carbon alternative made from feedstocks such as used cooking oil and crops. But despite its potential, sustainable aviation fuel makes up less than 1% of global jet fuel use, mainly due to high production costs and limited supply.

A new study in Nature Sustainability points to a promising breakthrough: using municipal solid waste as a reliable, low-emission, cost-effective feedstock for sustainable aviation fuel.

Researchers from Tsinghua University and the Harvard-China Project on Energy, Economy, and Environment evaluated municipal solid waste-based jet fuel produced through industrial-scale gasification and Fischer-Tropsch synthesis. A life cycle analysis found that jet fuel made from municipal waste could reduce greenhouse gas emissions by 80-90% compared with conventional jet fuel. The main technical hurdle lies in scaling up gasification systems for widespread use.
