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. 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 Saturday comments: I’m here at my friend Greg’s place in Sebastopol, CA

Good day everyone, I hope you have a great Saturday wherever you happen to be spending it.

415am, it’s a foggy morning, with a low temperature of 45.5 degrees.

I’m up and at it earlier than usual, as I want to drive into Santa Rosa and play Pickleball this morning, at a place called Finley Park. I’ve played there in the past, and there’s lots of courts, so the waiting time between games isn’t too long fortunately.

 

Hawaii’s Broad Brush Weather Overview:  Moderate trades will continue this weekend, with enhanced showers decreasing through this afternoon. Dry trade wind weather will continue Sunday, with wind speeds starting to pick up slightly by Sunday night, as a high pressure system builds north of the islands.

Brief periods of showers will pass through the islands through early next week, in a moderate to breezy trade wind weather pattern. The middle of next week will be on the wet side for most islands, especially in the overnight to early morning hours, as a band of unstable clouds moves in from the northeast.

Hawaii’s Weather Details:  Satellite imagery shows an upper trough of low pressure moving into the northwest islands, and a band of low clouds from an old frontal boundary at the surface level. This upper trough will help to enhance trade wind showers through the morning hours.

An upper ridge of high pressure will build in behind this trough of low pressure, as it passes from west to east across the state today, increasing stability and decreasing shower coverage. Sunday will be the most favorable weather day of the weekend for outdoor activities.

Strong winds aloft enhanced by this passing upper trough will continue to support High Wind Warning conditions for the highest Big Island summits of Mauna Kea and Mauna Loa. Winds at summit level will decrease quickly by around sunset, as the upper trough passes east of the Big Island.

From Sunday night into Tuesday, a weak high will build just north of the state. Fair weather will continue for most areas, with a slight increase in our trade winds from moderate into the moderate to breezy range. One wrinkle in this forecast is the Hilo side of the Big Island and portions of East Maui, which will continue to see periods of enhanced showers.

From Tuesday night into Thursday morning, a band of unstable clouds will move from northeast to southwest across all islands. Expect increasing shower trends, favoring windward and mountain areas especially in the overnight to early morning hours.

From Thursday onward, typical trade wind weather will continue for the rest of the week, with brief windward and mountain showers possible.

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 Details:  High pressure building in from the north-northwest will drift east and keep trade winds moderate to fresh through this weekend. The ridge of high pressure should rebuild early next week, which will produce fresh to locally strong trade winds once again.

The current south swell will hold than steadily decline Sunday. A series of small swells will persist through the weekend, keeping south facing shores from mostly flat. Small north swella will continue into the weekend. A larger moderate north swell reinforcement will arrive Sunday. A rise in surf  is expected, but the north swell looks to peak Sunday well below High Surf Advisory levels. Surf along east facing shores will remain small but can expect a slight increase early next week as the trades strengthen.

Interesting:  Warming of Antarctic Deep-Sea Waters Contribute to Sea Level Rise in North Atlantic, Study Finds

A new study published in the journal Nature Geoscience led by scientists at University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, and the National Oceanic and Atmospheric Administration’s Atlantic Oceanographic and Meteorological Laboratory, found that human-induced environmental changes around Antarctica are contributing to sea level rise in the North Atlantic.

The research team analyzed two decades of deep sea oceanographic data collected by observational mooring programs to show that a critical piece of Earth’s global system of ocean currents in the North Atlantic has weakened by about 12 percent over the past two decades.

“Although these regions are tens of thousands of miles away from each other and abyssal areas are a few miles below the ocean surface, our results reinforce the notion that even the most remote areas of the world’s oceans are not untouched by human activity,” said the study’s lead author Tiago Biló, an assistant scientist at the Rosenstiel School’s NOAA Cooperative Institute for Marine and Atmospheric Studies.
