Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. 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 Tuesday comments: I’m here at my friend Greg’s place in Sebastopol, CA

Good day everyone, I hope you have a great Tuesday wherever you happen to be spending it.

403am, it’s a cloudy morning, with a low temperature of 50 degrees.

It’s a cool and cloudy morning here in Sebastopol. I just got back from walking along Moonshine Rd, with Greg’s dog Blaise, on a leash. We probably walked about two miles, which is just about right for me in the morning. I’m skipping driving into Santa Rosa for more Pickleball, although will likely go again tomorrow morning.

My friend Greg told me that the power will go out this morning, and likely be out into the early afternoon (California time). Thus, I won’t be able to do my regular updates to this website until the power comes back on.

 

Hawaii’s Broad Brush Weather Overview:  Breezy and showery trade wind conditions will continue through Thursday, with clouds and showers favoring windward and mountain locations. Trade winds may ease slightly this weekend as the ridge weakens to the north of the state.

Hawaii’s Weather Details: Models remain in good agreement depicting the wet trade wind pattern persisting through Thursday, as bands of low-level moisture move through. The initial band has led to an increase in windward shower coverage, with some spilling over into leeward sections of the smaller islands.

Observations at the rain gauges across the island chain reflect this increase in showers, with accumulations reaching a quarter to three quarters of an inch, with localized higher amounts above 2-4 inches over the past 24 hours.

Expect these showery weather trend to persist through mid-week, with the next band approaching from the northeast. The shower coverage should trend down by Friday, as this second showery band moves out and drier air moves in.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map

Marine Environmental Details:  High pressure north of the state will slowly drift east and strengthen over the next few days, resulting in fresh to strong trade winds over the islands. A Small Craft Advisory remains in effect for higher winds through Wednesday, covering most Hawaiian coastal waters from Oahu to Big Island.

Surf heights along all shores will remain below advisory thresholds through the weekend. A small northwest swell will arrive late Wednesday and continue through Saturday. Choppy, rough surf is expected all week along east facing shores, due to the trade winds. South shores will see small swell pulses through rest of the week.

Interesting:  AI Weather Forecasts Captured Ciaran’s Destructive Path

Artificial intelligence (AI) can quickly and accurately predict the path and intensity of major storms, a new study has demonstrated.

The research, based on an analysis of November 2023’s Storm Ciaran, suggests weather forecasts that use machine learning can produce predictions of similar accuracy to traditional forecasts faster, cheaper, and using less computational power.

Published in npj Climate and Atmospheric Science, the University of Reading study highlights the rapid progress and transformative potential of AI in weather prediction.

Professor Andrew Charlton-Perez, who led the study, said: “AI is transforming weather forecasting before our eyes. Two years ago, modern machine learning techniques were rarely being applied to make weather forecasts. Now we have multiple models that can produce 10-day global forecasts in minutes.
