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%.

Hawaii’s Broad Brush Weather Overview: A weak cold front, currently moving towards Oahu through the Kauai Channel, will continue to spread clouds and enhanced showers to the other islands through Saturday, as the frontal cloud band slowly drifts eastward down the island chain. Moderate to breezy north to northeast winds will blow in as the front passes each island.

Another stronger front is forecast to approach late Sunday, bringing breezy southwesterly kona winds into Monday. More significant showers will develop along this next frontal band, as these clouds and showers march eastward down the island chain Monday into Tuesday, before stalling and diminishing near the Big Island Wednesday. Expect cool and dry, breezy northwesterly to northerly winds to blow into the region after the front passes each island.

Hawaii’s Weather Details:  Satellite imagery shows the leading edge of the front passing eastward through the Kauai Channel towards Oahu. A few high clouds will stream in from a polar jet stream farther to the north. Expect cloudy skies and periods of showers to continue over Kauai and Niihau today, Oahu will see increasing shower trends this morning as the frontal cloud band arrives.

Clouds and showers along the frontal band will reach Molokai around noon, Lanai and Maui around 2pm this afternoon, and the Big Island just after midnight Saturday morning. Rainfall will favor north and east slopes of each island with decreasing rainfall amounts along the front as it passes through each island. Cool northerly winds with decreasing shower trends will blow in behind the front, indicating the cold front has passed through your local area.

A high pressure cell on an eastward track will pass just north of the Hawaiian Islands this weekend, producing a brief period of fairly stable easterly trade winds lasting into Sunday morning for most islands. The next cold front will then approach the islands from the northwest, cold air and troughing aloft will break down the ridge near the islands, producing southwesterly kona winds from Sunday afternoon onward. A few passing showers may develop in this southwesterly wind pattern, favoring south and west slopes of each island into Monday.

Models show this cold front moving into Niihau and Kauai around noon Monday with similar trends of increasing showers along the frontal cloud band. This front appears slightly stronger than the previous front, and more rainfall will likely develop with this next system. The latest timing on this front shows the frontal cloud band spreading showers into Oahu by Monday evening, to the islands in Maui County from Monday night into Tuesday morning, and finally stalling near the Big Island Tuesday afternoon into Wednesday. Storm total rainfall amounts of 0.25 to 0.50 inch with locally higher amounts are possible as the front passes each island. Cool, dry and stable northwesterly to northerly winds will once again blow in behind the front.

This weather pattern continues into the end of next week, another brief period of easterly trades as a high center passes north of the state, followed by southwesterly kona winds ahead of yet another, even stronger cold front approaching the islands, bringing potentially heavy rain showers and thunderstorms for the end of next week. Stay tuned as the weather forecast with this third front may turn threatening and island by island impacts will evolve over time.

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.
