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 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.

Hawaii’s Broad Brush Weather Overview…as of Thursday afternoon: 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, and land breezes which will help to bring clearing overnight. Moderate to locally breezy trades will return early next week, bringing back the typical windward and mountain showers. A slight weakening and veering of the trade wind flow may unfold for the latter part of next week.

Short Term Update: Radar and visible satellite imagery show scattered showers moving into windward and mountain areas of the Big Island to Oahu. After this current batch of moisture moves through, drier air will filter in this afternoon, decreasing windward and mountain low cloud and shower coverage. With the local pressure gradient projected to gradually weaken, localized sea breezes may develop this afternoon, allowing for the formation of low clouds and showers over some leeward and interior areas. If the winds weaken enough tonight, land breezes may develop and help to clear out some of the clouds and showers, in which case the chance of rain may need to be decreased slightly.

Weather Details for the Hawaiian Islands…as of Thursday afternoon: Moisture-laden trades will continue to move across the Hawaiian Islands this morning, responsible for allocating isolated to scattered showers across windward and mountain areas through the afternoon, increasing to scattered to numerous overnight into Friday morning. Shower coverage will decrease thereafter as drier conditions arrive over the state, then expected to persist through the weekend.

As the subtropical ridge overhead slowly begins to weaken and slide northeastward, trades will respond, gradually easing through the remainder of the week. This will open the doors for localized land and sea breeze development through the weekend, introducing leeward and interior clouds and showers during the afternoon hours, followed by overnight clearing. However, given the lack of moisture available, shower activity during this time will likely remain light and short-lived.

Model guidance continues to support the return of light to moderate trades early next week, as a strengthening surface ridge builds north of the island chain. Additionally, model guidance showcases bands of moisture arriving from the east of the Hawaiian Islands. leading to periodic increases in shower activity across windward and mountain areas as early as Sunday night and prevailing through the latter end of next week.

Marine Environmental Conditions…as of Thursday afternoon: 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 currently located over 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.
