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

I spoke with a friend who works at the NWS forecast office in Honolulu, and he said that there are major software and personnel changes going on now, so expect less weather information for the time being!

Linda and I played pickleball in Mill Valley this morning. I played well enough although for some reason I didn’t have the best mood.

It’s a sunny day although the breeze off the ocean is chilly.

The weather here in Marin County is forecast to cool considerably tomorrow and turn cloudy.

Weather Wit of the day:  Slushy Roads – The wet slide story

 

Hawaii’s Broad Brush Weather Overview:  Heavy rain and isolated thunderstorms are anticipated over and in the vicinity of Kauai tonight while quiet conditions with isolated showers are expected elsewhere. Moderate to breezy southeast winds return Thursday and continue through the weekend.

Hawaii’s Weather Details:  Quiet conditions prevail for Oahu through Big Island, while convergent southerly flow focuses pockets of moderate to heavy rain over interior Kauai. At present, heavy rainfall has been confined to Kauai`s interior where incoming clouds are maximized. However, the onset of the nocturnal period brings concern that incoming convection south of Kauai may deepen and bring a more robust flash flooding threat during the overnight period.

The Flood Watch has therefore been extended through tonight. Organized low-level convergence then begins shifting west of the island late tonight into Thursday, as winds back to southeasterly in response to the parent low drifting away from the islands. This is expected to end the threat for organized heavy rainfall and confidence is high that the Flood Watch will be allowed to expire on schedule.

Upper ridging downstream of the resident low undergoes subtle amplification during the latter half of the week, as the low is gradually absorbed into prevailing westerly mid-latitude flow. This will allow moderate to locally breezy southeast winds to develop for the remainder of the week. Shadowing downstream of the larger islands in this pattern will lead to locally diminished winds over the western end of the state, introducing potential for an expansion of sea breezes during the afternoon.

This in turn increases potential for interior clouds and a few showers during the afternoons, especially during the latter half of the weekend, when long range guidance indicates renewed mid-level troughing may further reduce the local gradient. Stability remains low throughout this time, suggesting that locally heavy showers will be possible on days when sea breeze convergence is maximized.

Hawaii’s Marine Environment:  Gentle to moderate southerlies continues over the western end of the state, with locally fresh southeast prevailing over the eastern half. A low settling several hundred miles northwest of the islands results in a chance of thunderstorms mainly in the vicinity of Kauai through Thursday.

The existing small, medium-period northwest swell peaked Tuesday afternoon, and will subside with little in the way of surf for north and west facing shores expected thereafter. A slightly larger long-period northwest swell is then expected this weekend, though surf is forecast to remain well below the advisory threshold for north and west facing shores.

A small, long period south-southwest swell will elevate surf along south facing shores above the summertime average, but still firmly below the advisory threshold as it peaks and holds. This swell then slowly declines during the rest of the week.

Lack of upstream trades favors near-to-below average surf along east facing shores, though some chop resulting from current southeast winds may reach the waters off of east facing shores during the next several days.

Interesting:  Seeking Nutrition, Not Sustainability, Reduces Food Waste

Consumers who are conscious of their nutrition exhibit behaviors that significantly reduce food waste, even more so than those whose behavior is driven by sustainability concerns, according to new research from the University of Adelaide.

Researchers surveyed 1030 Australians and found that nutrition-conscious consumers had many waste-reducing habits and, as a result, generate less food waste.

“People who prioritize healthy eating tend to plan meals and avoid over-purchasing – behaviors that significantly reduce food waste,” says lead author, Dr. Trang Thi Thu Nguyen, from the University of Adelaide’s Center for Global Food and Resources, School of Economics and Public Policy.

“The idea that sustainability-conscious consumers would also waste less food seems logical. After all, they actively seek out ethical and environmentally friendly products.
