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.

Glenn’s Thursday comments:  I’m at home here in upper Kula, Maui, Hawaii

It’s mostly clear, with calm winds at my place, and with a low temperature of 53 degrees and the relative humidity is 85%

845am, it’s clouding up quickly this morning, and it looks like it could be another showery day…which would be fine with me. I should add that there is some sunshine down along the leeward coast.

115pm, played Pickleball in Haiku this morning, which was energizing as usual. It’s a very sunny afternoon in most areas around Maui County, although there are some well developed cumulus clouds on the slopes of the Haleakala Crater in places.

414pm, it’s as clear and sunny as it gets, ever! There are essentially no clouds anywhere here on Maui, with even the entire Haleakala Crater slopes cloud free!

627pm, it’s still very sunny, although we’re beginning to see some thin high cirrus clouds arriving from the southwest, which will likely give us some nice color at sunset…at least on the Big Island and Maui.

854pm, it has remained clear so far this evening, and with the dry air, my temperature has slipped already to 56.6 degrees.

Hawaii’s Broad Brush Weather Overview…as of Thursday evening: Light to moderate trades will gradually weaken through Saturday, allowing for the development of localized sea breezes which will bring clouds and a few showers to leeward and interior areas each afternoon, followed by clearing with land breezes overnight. Moderate to locally breezy trades will return early next week, bringing back the typical windward and mauka showers. A slight weakening of the trade wind flow may unfold for the latter part of next week.

Weather Details for the Hawaiian Islands…as of Thursday evening: Light to moderate trades will gradually weaken through Saturday, as the subtropical high to the northeast gets pushed farther away, displaced by a low pressure system developing to the far north and advancing toward the Gulf of Alaska. These lighter background winds across the state will allow for localized sea and land breeze cycles to develop, bringing afternoon leeward and interior showers, followed by clearing overnight. The sea breeze cycle already kicked off earlier this afternoon, with showers developing most notably over leeward Oahu and the Kona slopes of the Big Island. With drier air filtering over the state this afternoon and lingering through the weekend, expect shower activity to be somewhat limited during this period.

Moderate to locally breezy trades gradually return Sunday night into early next week, as ridging builds back in from the northeast. Pockets of deeper moisture caught up in the redeveloping trade wind flow will bring periodic increases in windward and mountain showers, particularly Sunday night into Monday.

Another developing low to the north may cause winds to weaken slightly across the islands for the latter half of the work week. An area of enhanced moisture will move in from the east around the same time, boosting dew points and bringing an increase in shower activity, particularly across the eastern end of the state. Most of these showers will likely be focused over windward and mountain areas, but if the winds become light enough, there may also be some isolated sea breeze showers over leeward and interior areas.

Marine Environmental Conditions…as of Thursday evening: High pressure far north of the area will weaken and move east, as a front passes by north of the islands. This will cause trade winds to weaken into the the gentle to moderate category with localized land and sea breezes through Saturday. Fresh to locally strong easterly trades will return Sunday through early next week as the surface ridges strengthens north of the state.

A small pulse of south-southwest swell will fill in today into Friday, keeping near average surf breaking along south facing shores.

Long-period energy from a storm that passed within our swell window around New Zealand earlier this week, is expected to gradually fill in locally late Friday through the weekend. Current guidance has this swell peaking Sunday into Monday, that will drive surf heights near warning levels. The swell is hitting the Samoa Buoy this morning, so increased confidence in the size of the swell is expected later today, as the swell fills in further there. This swell will also coincide with the peak monthly tides and will likely lead to significant wave runup and minor coastal flooding during the first half of next week, particularly during the peak daily high tide cycles. A marine weather statement is also anticipated due to the threat of harbor surges. South shore surf will then remain elevated through much of next week, due to the slow decline of this large south swell and a series of more overlapping southerly swells.

East shore surf will slowly decline below seasonal averages through the the weekend as trades ease, then pick up a notch next week as more breezy trades return. No significant swells expected elsewhere.

Bay of Campeche:

A broad area of low pressure is likely to form over the Bay of Campeche on Friday from a westward-moving tropical wave located near the coast of the Yucatan Peninsula of Mexico. Environmental conditions are forecast to be only marginally conducive for development before the system moves inland over eastern Mexico late Saturday or Sunday.

Interesting: ‘Cautiously Optimistic’: Canada’s Agri-Food Sector Requires Coordinated Approach to AI

Adopting artificial intelligence across the agri-food sector requires a coordinated integration, otherwise Canada risks falling behind in both productivity and market competitiveness.

This conclusion from Dr. Rozita Dara, professor and Research Impact Leadership Chair, co-director of AI4Food, is outlined in a new report, “AI 4 Food: Artificial Intelligence for a Thriving Agri-Food Ecosystem in Canada.”

The report is the culmination of a three-part national dialogue series that brought together academics, government, industry and producers. At issue was Canada’s positioning for AI implementation in agriculture and food systems, food safety and data sovereignty.

The use of AI and other data-driven technologies in all sectors is rapidly growing. “Food systems cannot be an exception,” Dara says.
