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 Saturday comments:  I’m here in Corte Madera, Marin County, California, at my friend Linda’s on a working vacation.

I just found out from my neighbor in upper Kula that heavy vog continues over at least Maui County.

Weather Wit of the day:  Do you think the ozone layer over Switzerland has a lot of little holes?

 

Hawaii’s Broad Brush Weather Overview:  Light winds will prevail through early next week, with land and sea breezes common over most of the state. A rather dry pattern will persist today, with a few showers affecting east and southeast facing slopes this morning, and a few leeward showers developing this afternoon.

The airmass will moisten up Sunday through Tuesday, bringing an increase in showers. Some of the showers could be heavy with a few rumbles of thunder possible early next week, as a disturbance aloft moves southward over the state. A return to more typical trade wind weather featuring mainly windward and mountain showers appears to take hold during the middle to latter part of next week.

Hawaii’s Weather Details:  Weather maps show a low north-northwest of Kauai, while a high is centered far northeast of Honolulu. Between these two features lies a trough of low pressure which is located around 125 miles northwest of Kauai. Infrared satellite imagery shows partly cloudy conditions in most areas. Radar imagery shows scattered showers moving into east and southeast facing slopes and coasts.

The low north-northwest of the islands and the high to the distant northeast will shift eastward this weekend, then shifts into a trough over the islands early next week. Winds will change little through early next week, with land and sea breezes dominant over most of the state, with light to moderate east- southeast winds persisting in unsheltered areas around Maui and the Big Island.

The troughing over the islands will gradually dampen out during the middle and latter part of next week, as high pressure builds to the north. This should allow a gradual return and strengthening of the trade winds across the state.

Meanwhile, the overall pattern will remain mostly unchanged and rather dry through tonight. A few showers will remain possible over east and southeast facing slopes and coasts overnight and during the morning hours, with a few showers developing in leeward areas this afternoon, then fizzling out in the evening.

The airmass will moisten up Sunday through Tuesday, as the moisture associated with an old trough moves over the state. A land/sea breeze pattern will remain in place, with showers favoring interior and leeward areas during the afternoon and evening hours, with showers mostly over the coastal waters or near the immediate coast at night.

A disturbance aloft diving southward over the state could bring locally heavy rainfall and even a few thunderstorms to portions of the island chain early next week. A return to more typical trade wind weather featuring mainly windward and mountain showers appears take hold during the middle to latter part of next week.

Hawaii’s Marine Environment:  Locally fresh southeast winds will gradually ease and become light and variable by Sunday, as a low pressure trough northwest of the Islands slowly weakens and shifts northeastward. Thus, a slight chance of thunderstorms remains northwest of Kauai. Light flow will continue into Monday and Tuesday, as the trough drops southward over the islands and brings a slight chance of thunderstorms to all waters. Trades eventually return mid-week as surface high pressure builds north of the state.

A small long-period northwest swell is forecast to cross the local waters, peak tonight into Sunday, then fade through early next week. This incoming swell has already reached Hanalei buoy, with the latest observation indicating the presence of long period energy.

Surf along north and west facing shores should remain near or below average, well shy of High Surf Advisory (HSA) criteria. By Thursday, a medium long-period north-northwest swell is forecast to enter our area and produce surf that may approach HSA.

Multiple small early season south swells will maintain small background southerly energy through mid next week. A rise in south swell energy is expected to arrive late Thursday, and last through next weekend. Weak upstream trade wind flow will keep surf along east facing shores near or below seasonal averages.

Interesting:  When It Comes to Reading the Room, Humans Are Still Better Than AI

Johns Hopkins research shows artificial intelligence models fall short in predicting social interactions, a skill critical for systems to effectively navigate the real world.

Humans, it turns out, are better than current AI models at describing and interpreting social interactions in a moving scene—skills necessary for self-driving cars, assistive robots, and other technologies that rely on AI systems to navigate the real world.

The research, led by scientists at Johns Hopkins University, finds that artificial intelligence systems fail at understanding social dynamics and context necessary for interacting with people and suggests the problem may be rooted in the infrastructure of AI systems.

“AI for a self-driving car, for example, would need to recognize the intentions, goals, and actions of human drivers and pedestrians. You would want it to know which way a pedestrian is about to start walking, or whether two people are in conversation versus about to cross the street,” said lead author Leyla Isik, an assistant professor of cognitive science at Johns Hopkins. “Any time you want an AI to interact with humans, you want it to be able to recognize what people are doing. I think this sheds light on the fact that these systems can’t right now.”
