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. Here’s the webcam for the (~10,023 feet high) Haleakala Crater 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 Thursday comments:  I’m with my friend Bob here at our vacation rental at Sea Ranch, Sonoma County, CA on a working vacation.

439am HST, it’s partly cloudy here at Sea Ranch with low clouds just offshore and lots of high cirrus clouds too, the low temperature was 44.5 degrees…with a chilly breeze,

1101am HST, Bob and I drove over to the pickleball courts here in Sea Ranch and there was someone with a hose cleaning the court surfaces…so no playing today. We have a rainy day on tap tomorrow, so likely no playing until the weekend. It’s way cloudy this afternoon here, although the rain is suppose to hold off until tonight.

551pm, we sat outside until it was almost dark, and watched the clouds associated with an approaching cold front thicken up. The rain is suppose to start falling around 9pm here in CA. It’s been perfect weather the first half of this working vacation, and now apparently the flood gates are opening over CA, and we’ll have off and on showers likely through the remainder of our stay here.

 

Hawaii’s Weather Highlights…as of Thursday evening: Gusty trade winds continue as high pressure remains north of the state. Drier conditions will prevail through the weekend, with light trade showers most numerous each morning in windward and mauka areas. High pressure will settle east of the state and weaken next week, significantly reducing the trade flow mid to late week.

Weather Narrative…as of Thursday evening: Increased shower coverage, associated with a decaying frontal boundary has largely dissipated outside of windward areas of Big Island. High pressure remains north of the state and continues to result in gusty trade winds. This high will ease Friday, while a reinforcing high from the northwest builds southeast Friday night. It will slide east well to the north of the state this weekend. Some increase of the trades is expected again Saturday night and early Sunday, before the high stalls to our northeast early next week.

The high will gradually weaken through mid-week, while a surface trough approaches from the west. The pressure gradient will relax and allow trades to weaken significantly mid to late next week. Trade wind showers will continue each day over windward and mauka areas, mostly during the overnight and early morning hours, particularly on the Big Island.

Fire Weather: Fuel conditions remain below critical thresholds due to the above average rainfall over the past few months. Due to the fuels, Red Flag Warnings are not expected at this time. Winds should ease slightly with a modest increase of humidities on Friday. Temperature inversion heights will remain between 5,500 and 7,000 feet across the state.

Marine Conditions…as of Thursday evening: Strong high pressure north of Hawaii will maintain fresh to near gale force winds across the marine areas through tonight. The Gale Warning has been discontinued in favor of a Small Craft Advisory (SCA) which covers all coastal waters. The SCA has been extended through tonight, with a gradual tapering of winds forecast and some uncertainty on how widespread strong trades will be by Friday. Look for high seas with a large north-northwest swell moving through the area.

A weakening front will drop south across central waters today as it weakens to a trough. This disturbance will bring increased shower activity to the area until it dissipates tonight. Though trade winds diminish some for Friday and Saturday, high pressure restrengthening northeast of the islands may bring more widespread strong winds Sunday and Monday to all waters.

Buoy 51201 near Waimea Bay observed the peak of the large, north-northwest swell late last evening with a 15 second period. A High Surf Advisory (HSA) remains in effect for north- facing shores of Kauai, Oahu, Molokai and Maui and west- facing shores of Kauai and Oahu.

The large swell will generally maintain, before declining this afternoon and falling below advisory criteria tonight. Surf will continue to decrease Friday, but will see a small rise on Saturday, with a new north-northwest swell, followed by a more significant north swell which could push surf back to advisory levels on Sunday.

Surf along east-facing shores will remain rough and choppy due to the strong trade winds through Friday, then may diminish slightly this weekend. A small, long-period south swell may bring a small rise to south shore surf today. Surf becomes tiny again Friday into the weekend for south-facing shores.

How High-Speed Ferries Can Reclaim Their Environmental Credentials

Norway has the technology and expertise needed to develop high-speed catamarans capable of operating even the longest routes. But something is missing.

“In less than five years, we could have a zero-emission high-speed passenger catamaran, capable of travelling at 20–35 knots and carrying 150–250 passengers. But that will require political will and decisive action,” says Professor Sverre Steen from the Department of Marine Technology at NTNU.

Steen is confident that Norway has a broad range of expertise and companies capable of commercializing hydrofoil passenger catamarans within a few years. This could help address some of the challenges associated with emissions from passenger transport, including over longer distances.

The high-speed ferry MS Baronessen has replaced its diesel engine with batteries. Its hull has been lengthened to accommodate the additional weight of the batteries. The vessel is also testing battery-swapping technology.
