Hawaii’s MountainsHere’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the 10,000+ feet high Haleakala Crater on Maui (The camera is working again). 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



Broad Brush Overview: High pressure located to the north of the state will generate moderate to locally strong trade winds through the early part of next week. A fragmented cold front just north of Kauai, will gradually drift south and provide an increase in trade showers Monday through Tuesday of next week.

Details:  The trade wind inversion over the island chain, which is limiting shower activity, will remain in place through the upcoming weekend. Light rainfall amounts are expected under this stable air mass. The strengthening trades have resulted in a Small Craft Advisory over the windier waters around Maui County and south of the Big Island….maintain the locally strong trades into Monday.

The remnants of a weak cold front to our north, will finally shift south by Monday into Tuesday morning. The models show the moisture with the boundary is capped at 10,000 feet, which is relatively shallow. The windward and mountain areas will receive the bulk of these showers, although some leeward areas on the smaller islands may see a few too. The current idea is that these showers will clear the islands by mid-day Tuesday.

Looking Further Ahead: The models show drier air moving over the state later next Tuesday into Wednesday. At the same time, our strong trade winds will be knocked back down into the lighter realms. The winds will be light enough by next Wednesday, that we could see onshore sea breezes and some afternoon cloud buildups over the slopes. This will occur as yet another early spring cold front approaches the state.

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 Conditions: High pressure north of the area will bring moderate to locally strong trade winds through early next week. A Small Craft Advisory (SCA) is now in effect for the typical windy waters around Maui County and the Big Island at least through Sunday. In addition, seas may reach border line small craft advisory levels for additional waters, as a new north-northwest swell builds tonight. Trades will ease towards the middle of next week as the surface high weakens and is pushed to the southeast by an advancing cold front. This front could reach the islands next Thursday.

Surf along north and west facing shores will be near advisory levels and will likely rise just above advisory thresholds tonight, as a new north-northwest swell builds. The reinforcing north-northwest swell is expected to peak tonight and Saturday, and then decline Saturday evening into Sunday. Several reinforcing northwest and north swells should continue to produce small to moderate surf for the first half of next week. By the middle of next week, a moderate northwest swell will be possible. As trade winds strengthen, rough surf along east facing shores will gradually increase, with wind swell reaching around the March average late Saturday into Monday. Very small southerly swell waves will be breaking on our leeward beaches.

Interesting: Flat-Earthers’ Cruise Will Sail to Antarctica ‘Ice Wall’ at the Planet’s Edge. Right – Organizers of an annual conference that brings together people who believe that the Earth is flat are planning a cruise to the purported edge of the planet. They’re looking for the ice wall that holds back the oceans.

The journey will take place in 2020, the Flat Earth International Conference (FEIC) recently announced on its website. The goal? To test so-called flat-Earthers’ assertion that Earth is a flattened disk surrounded at its edge by a towering wall of ice.

Details about the event, including the dates, are forthcoming, according to the FEIC, which calls the cruise “the biggest, boldest adventure yet.” However, it’s worth noting that nautical maps and navigation technologies such as global positioning systems (GPS) work as they do because the Earth is … a globe.

Believers in a flat Earth argue that images showing a curved horizon are fake and that photos of a round Earth from space are part of a vast conspiracy perpetrated by NASA and other space agencies to hide Earth’s flatness. These and other flat-Earth assertions appear on the website of the Flat Earth Society (FES), allegedly the world’s oldest official flat Earth organization, dating to the early 1800s.

However, the ancient Greeks demonstrated that Earth was a sphere more than 2,000 years ago, and the gravity that keeps everything on the planet from flying off into space could exist only on a spherical world.

But in diagrams shared on the FES website, the planet appears as a pancake-like disk with the North Pole smack in the center and an edge “surrounded on all sides by an ice wall that holds the oceans back.” This ice wall — thought by some flat-Earthers to be Antarctica — is the destination of the promised FEIC cruise.

There’s just one catch: Navigational charts and systems that guide cruise ships and other vessels around Earth’s oceans are all based on the principle of a round Earth, Henk Keijer, a former cruise ship captain with 23 years of experience, told The Guardian.

GPS relies on a network of dozens of satellites orbiting thousands of miles above Earth; signals from the satellites beam down to the receiver inside of a GPS device, and at least three satellites are required to pinpoint a precise position because of Earth’s curvature, Keijer explained.

“Had the Earth been flat, a total of three satellites would have been enough to provide this information to everyone on Earth,” Keijer said. “But it is not enough, because the Earth is round.”

Whether or not the FEIC cruise will rely on GPS or deploy an entirely new flat-Earth-based navigation system for finding the end of the world, remains to be seen.
