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.

Glenn’s Aloha Friday comments:  I’m here at home in upper Kula, Maui

It mostly clear early this morning although with voggy air, with a low temperature of 50 degrees at my place, and the relative humidity 76%.

1240pm, skies have become partly to mostly cloudy early this afternoon, as a cold front slides down the island chain towards Maui County. We still have lots of vog in our skies, although hopefully the northerly breezes in the wake of the front will help to ventilate some of these volcanic emissions away! Actually, the northerly breezes are blowing through the current cold front…and they are bringing a slight cooling our way early this afternoon even before the front arrives.

505pm, a cool northerly breeze has been brought over Maui County along with the front, along with some generally windward showers. Here in upper Kula we have foggy weather although dry. The temperature feels cooler than the 67.6 degrees.

630pm, the clouds and fog cleared up here in Kula around sunset, and I can see the large near full moon rising in the east! It’s chilly here at my place, with the temperature 60.6 degrees. A friend who lives in Kihei just told me that it rained for about 45 minutes…with .58″ in this rain gauge!

810pm, the temperature here at my Kula weather tower is a chilly 55.2 degrees, although it feels cooler than that. The skies are clear here in the upcountry area, allowing a great view of the almost full moon rising, with a planet right by its side. The full moon is this coming Sunday, and is called the Snow Moon is some places.

Hawaii’s Broad Brush Weather Overview: A weak cold front, moving across Maui, will stall and dissipate near the Big Island tonight through Saturday. This front will bring enhanced clouds and light to occasionally moderate showers to mainly windward portions of both Maui County and the Big Island.

The next front will begin to approach the islands on Sunday and bring moderate southwest kona winds. These winds will peak on Monday, directly ahead of the front, and may become quite gusty at times. Expect some pre-frontal showers developing over the western half of the state on Sunday, but the main rainband with pockets of heavier rain should push down the chain on late Monday into early Tuesday. Cool and dry, breezy northwesterly to northerly winds will blow into the area after the front passes each island.

Hawaii’s Weather Details:  Visible satellite loops showed a disorganized line of low clouds aligned northeast to southwest over the central islands. This line was trudging slowly southeast towards the Big Island. Rain amounts since midnight have been rather minor with this system, topping out between 0.25″ and 0.50″ along windward and mountain sections of Oahu and Kauai, with lower amounts leeward. Meanwhile, Molokai and Maui have so far registered only a few hundredths of an inch. The weak front may actually dissipate before reaching the Big Island tonight. Thus, there’s been a scaling back of some of the precipitation chances for windward Big Island tonight into Saturday morning.

A post frontal light to moderate northeasterly flow will dominate on Saturday across the smaller islands, bringing limited cloud cover and showers to windward and mountain areas. For the Big Island, afternoon sea breeze development, combined with shallow residual moisture from the deceased front, will slightly enhance shower activity on the lower slopes of Mauna Kea and Mauna Loa.

Late this weekend, the next cold front will approach the state from the northwest. In response, southwest kona winds initially develop across the islands late Sunday, then quickly ramp up through Monday afternoon. Models have been consistent with these stronger winds, depicting speeds of sustained 20 to 30 mph with higher gusts. Stronger winds will likely occur over mountain ridge tops and in the lee of mountain ranges. If guidance maintains or trends up, a wind advisory would be need for select mountain areas, and those areas to the northeast of the mountains. Big Island summit winds will likely become strong late Monday and may break advisory thresholds.

In addition, a moderate to locally heavier band of rain appears to accompany the front. Though the ECMWF model is slightly weaker with the upper level support and available moisture, both the GFS and ECMWF models show generally a half inch to an inch total rainfall accumulations along south and west facing portions of the islands Monday through Tuesday. As always, locally higher amounts are possible. The speedy nature of the front should mitigate the flood risk, but some minor flooding is not out of the question.

Tuesday into Wednesday, post frontal breezy north to northwest flow will bring in a drier and cooler airmass. Winds will continue to veer easterly on Thursday as transient surface high pressure moves north of the region. Long range models are suggesting that yet another system to affect the islands by next weekend, but details are still to hazy that far out into the extended range.

Hawaii’s Marine Environment:  A front moving over the western coastal waters will continue moving southeast down the island chain. Light and variable winds ahead of the front will be replaced by moderate to fresh north to northeasterly winds in its wake. Light easterly trade winds will briefly return to Hawaiian waters Saturday night and early Sunday, with moderate to locally strong southwesterly winds developing ahead of the next cold frontal system, approaching from the northwest late Sunday through Monday. This next cold front will move down the island chain late Monday night through Tuesday, increasing chances for showers. Fresh to locally strong northwesterly winds will build in behind the front as it passes.

Nearshore buoys at Hanalei and Waimea show that a moderate to large northwest swell is moving through the islands, pushing surf along north and west facing shores well into advisory levels. However, a bigger and longer period northwest (300-320 degree) overlapping swell is expected to fill in. This second swell is expected to peak this afternoon and evening, pushing surf heights above warning levels into Saturday for select north and west facing shores. These large northwest swells will decline from Saturday into early next week. Looking ahead, an extra large northwest (310-330 degree) swell may fill in from Tuesday through Wednesday of next week.

A Coastal Flood Statement remains in effect for low-lying shoreline and roadways due to the combination of large surf and higher than predicted water through Monday afternoon.

Surf along east-facing shores will remain small due to the lack of trades locally and upstream of the state. Surf along south-facing shores will also remain small over the next several days.

Interesting:  Cleaner Ship Fuel Changed Clouds, But Not Their Climate Balance

To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020. That shift created an inadvertent real-world experiment in how man-made aerosols influence cloud formation over the ocean.

A team of atmospheric scientists led by University of Utah professor Gerald “Jay” Mace used this rare opportunity to explore the impact of reduced emissions on marine boundary layer clouds over the eastern North Atlantic. They discovered clouds’ internal structure changed, featuring fewer, but larger droplets of water. Yet the clouds’ reflectivity of sunlight surprisingly remained unchanged.

“You couldn’t plan this type of thing,” Mace said. “The shipping in the entire world went from one thing to another, almost like the flick of a switch, and it just so happened that that had a known effect on clouds globally. Doing a natural experiment like this, I don’t think it could ever happen again, unless we went back to sulfur fuels.”

‘Ship tracks’ above the northern Pacific Ocean. These patterns are produced when fine particles from ship exhaust float into a moist layer of atmosphere. The particles seed new clouds or attract water from existing cloud particles. These tracks virtually disappeared after 2020 when shipping vessels switched to cleaner fuelds.
