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.

Wow, 73mph gust a Puuloa down on the Big Island, and a 65mph gust at Na Kula on Maui during the afternoon Wednesday!!

Hawaii’s Broad Brush Weather Overview: A broad high remains the dominant feature for much of our Central Pacific, and will aid in maintaining breezy to windy trades across the Hawaiian Islands through this evening. Enhanced shower activity and cloud coverage will persist, namely for windward and mountain areas. Trades will begin to weaken to a more moderate level by Friday, in response to the high weakening and moving eastward away from the Hawaiian Islands.

Hawaii’s Weather Details:  The latest surface analysis displays a broad 1034 millibar area of high pressure well north of the Hawaiian Islands, still maintaining relatively breezy to windy trades across the islands. Latest model guidance suggests that the trades will be somewhat similar today as they were the previous 24 hours, especially over the Kohala District on the Big Island, where the strongest winds have been noted so far.

Because of this, the current Wind Advisory for portions of Maui County and the Big Island through 6pm today). Model guidance highlights winds will gradually ease thereafter, becoming more moderate to locally breezy, and fall outside of advisory criteria.

Simultaneously, radar and satellite imagery continues to showcase enhanced showers moving into windward and mountain areas, especially for the southern islands including Maui County and the Big Island. Precipitable water (PWATs) continue to show additional areas of moisture embedded in the trades upstream of the islands. This will keep windward and mountain showers going through the week, with a few showers likely spilling over into leeward areas during the overnight and early morning hours. Shower activity looks to gradually taper off over the weekend, as a drier and more stable air mass briefly moves into the area.

The latest guidance for the forecast early next week is largely unchanged from the past few days. Model guidance of the GFS continues to show a surface trough producing a southerly flow across the islands, bringing an abundance of tropical moisture with it around Monday or Tuesday of next week. If this proves fruitful, it could lead to a period of moderate to heavy rainfall — on the order of 3 to 4 standard deviations above normal for total precipitable water.

Conversely, model guidance of the ECMWF depicts tropical moisture remaining just south of the state, negating the heavy rainfall threat. Both models do show a depiction of a cold front advancing southward in the vicinity of the Hawaiian Islands through the first half of the week. Given the vast differences between the two models, there is no obvious outcome, generating quite a fair bit of uncertainty going forward. Further analysis on model trends over the next several days will be required to determine which model will become the favored scenario.

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.
