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 Tuesday comments:  I’m here at home in upper Kula, Maui

It’s mostly clear early this morning here at my location, with a very chilly low temperature of 46 degrees, and the relative humidity is 84%.

254pm, it’s sunny to partly cloudy here on Maui, with still some cloudy areas along the windward sides. The breezes come and go, actually the perfect to day to dry my clothes on the line today.

606pm, clouds with some showers along the windward sides, generally fair weather leeward, at least here on Maui.

9pm, the afternoon clouds that gathered over these leeward slopes of the Haleakala Crater have cleared, and as such, my outdoor temperature sensor is reading a chilly 49.1 degrees.

Hawaii’s Broad Brush Weather Overview…as of 815pm Tuesday:  An upper level ridge moving over the area has brought a return of trade winds and cooler, drier air. Trade showers, mostly windward and mountains, will continue through Thursday. An approaching trough will turn winds out of the southeast Friday, allowing warmer more moist air to move into the region. A wet cold front appears to be headed into the state Sunday and may linger for a couple days.

Update as 815pm: Currently at the surface, a 1031 millibar high is centered about 1500 miles north, and is driving moderate to locally breezy northeasterly trade winds across the island chain. Infrared satellite imagery shows partly to mostly cloudy conditions across the state, with cloud coverage the greatest in windward and mountain areas. Radar imagery shows numerous showers affecting windward slopes and coasts, with a few showers spilling over into leeward areas at times.

High pressure will hold in place to the distant north, maintaining moderate to locally breezy trade winds across the island chain. Showers will continue to favor windward and mountain areas, with the occasionally leeward spillover. There should be a decrease in shower coverage and leeward penetration of showers on Wednesday, as building low to mid-level high pressure ridging helps to lower inversion heights across the island chain.

Hawaii’s Weather Details…as of 357pm Tuesday: Satellite shows mostly cloudy skies windward and mountains, and clear to partly cloudy skies elsewhere. Radar is picking up trade showers, mainly windward, with rainfall amounts relatively light. Winds were averaging 10-20 mph, and mostly coming out of the northeast. An upper level ridge axis will continue to move from west to east tonight through Thursday. As it finally moves off to the east Thursday night, we will begin to feel the effects of an approaching upper trough.

This in turn will help create lower surface pressure to our northwest, and veer our winds out of the southeast. Warmer and more moist air will be drawn into the area, and a land- and sea-breeze pattern will likely develop this weekend. As the upper trough axis gets closer, a cold front will move close to the western part of the state late Friday. The latest guidance depicts this front as then stalling for 24 to 48 hours, before pushing well into the state Sunday.

Showers are expected to increase across western islands first, then all the way to the Big Island late Sunday into Monday. These types of systems are always difficult for guidance to accurately forecast this many days out, so expect some changes to timing and location as we go through the work week. At this time, the potential is there for periods of heavy rain this weekend and into early next week.

Hawaii’s Marine Environment…as of 317am Tuesday: Strong high pressure remains far north of the state, while a weakening surface trough lingers in the far southeast offshore waters. Northeasterly trade winds look to strengthen to fresh to strong speeds through tonight, before gradually easing to locally strong speeds over just the windier waters and channels around Maui County and the Big Island Wednesday and Thursday. A Small Craft Advisory (SCA) has been expanded to all coastal waters and extended through tonight, due to a combination of winds and mainly seas above SCA criteria, due to the large north-northeast swell currently impacting the islands. An approaching cold front will likely cause winds to decline and veer out of the southeast Thursday night into Saturday.

A large, long period north-northeast (010-030 deg) swell has peaked and will look to hold before declining through the end of the week. This swell will produce breaking waves at High Surf Warning levels across most north and east facing shores through this afternoon.

Due to the direction of the large swell, exposed west facing shores of West Maui, western Molokai, and North Kohala on the Big Island will likely experience High Surf Advisory conditions. The north-northeast swell will gradually decline tonight at High Surf Advisory (HSA) level conditions through Wednesday, before continuing to decline through Friday. In addition to this swell, a small pulse of overlapping west-northwest swell is expected through Wednesday. Due to the direction of the large north-northeast (010-030) swell, some overwash will be possible along low-lying coastal roads and infrastructure in windward areas, especially in the Keaukaha area east of Hilo. Hazardous conditions and heavy surges are expected in north facing harbors, mainly in Hilo and Kahului.

South facing shores will remain tiny due to a small background southwest swell, before flat wintertime surf will continue along south facing shores through the end of the week week.

Interesting:  Research Shows Best- and Worst-Case Scenarios for a Warming Antarctica

Antarctica’s pale expanses of ice keep water locked up and reflect heat from the planet — but the climate crisis is putting these safeguards at increasing risk. Antarctica is warming much faster than the global average, which could destroy its ecosystems and put other parts of the planet at risk by driving sea level rise and damaging food chains.

Now scientists have modeled the best- and worst-case scenarios for climate change in Antarctica, demonstrating just how high the stakes are if we don’t act now — but also how much harm can still be prevented.

“The Antarctic Peninsula is a special place,” said Professor Bethan Davies, lead author of the article in Frontiers in Environmental Science and UK national nominee for the 2026 Frontiers Planet Prize. “Its future depends on the choices that we make today. Under a low emissions future, we can avoid the most important and detrimental impacts. However, under a higher emissions scenario, we risk the loss of sea ice, ice shelves, glaciers, and iconic species such as penguins.
