~~~ Hawaii Weather Narrative ~~~

 

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

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

445am, it’s clear to partly cloudy early this morning here in Kula, with a low temperature of 54.5 degrees at my place.

 

Hawaii’s Broad Brush Weather Overview:  A broad high pressure ridge north of the Hawaiian Islands will keep moderate trade winds in the forecast through the first half of next week.

Satellite imagery this morning shows an unsettled patch of clouds moving through the western islands with more stable clouds east of the state drifting into the Big Island and Maui on the trade winds.

Only brief periods of showers are forecast over windward and mountain areas from this afternoon into early next week, as an upper level ridge settles in over the region.

Hawaii’s Weather Details:  Satellite imagery this morning shows an unsettled patch of clouds moving through the western islands, with more stable clouds east of the state drifting into the Big Island and Maui on the trade winds. This weakly unstable patch of clouds will keep passing showers in the forecast for windward and mountain areas of Oahu and Kauai through the early morning hours. Drier conditions will spread to all islands starting later this morning and last into early next week.

A broad subtropical ridge will remain in place north of the Hawaiian Islands into next week. An upper level ridge will then settle in over the islands producing strong and stable subsidence today through Monday. Increasing downward vertical motions (subsidence) under this upper ridge will lower the trade wind thermal inversion heights, limiting vertical cloud development, and thereby decreasing shower coverage. This upper level ridge will lift north Monday and Tuesday, opening the door for a slight increase in windward and mountain shower coverage trends.

Long range weather models continue to suggest that another low level wave in the easterlies may transit through the Hawaii region by the middle of next week, potentially increasing our showers, as this trough passes from east to west down the island chain. This next weak system may be our next best chance for decent rainfall amounts over windward and mountain areas.

More numerous showers are possible over windward and mountain areas from Tuesday night through Wednesday night, as this system slowly passes through each island. Rainfall amounts will also increase in this pattern during the typical overnight to early morning diurnal rainfall maximum, with some windward and mountain areas possibly seeing 0.10 to 0.25 inch amounts.

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 / Vog map animation

Hawaii’s Marine Environment:  The upstream pressure gradient from high pressure far northeast of the islands will weaken the next couple of days, as troughing develops over the eastern Pacific. Trades may occasionally become locally fresh, especially in the Alenuihaha Channel, through Friday morning.

No significant swells are expected from any direction for the remainder of the week. A series of small south-southeast swells will keep south-facing shores from going completely flat through the weekend. A small fetch of strong northeast winds off the U.S. Pacific Northwest coast will generate a very small northeast swell that is scheduled to arrive this holiday weekend.

Higher than normal water levels, in tandem with new moon tides, has produced higher than normal water levels around Big Island. Water levels have exceeded 3 feet above Mean Lower Low Water during the past few afternoon’s high tides. This will continue to create minor coastal flooding issues through the weekend. Peak water levels of around 3.5 feet are expected during periods of high tides. Therefore, a Coastal Flood Statement highlighting this flooding will remain in effect for Big Island’s coastal zones for the remainder of the week.

 

 

 

World-wide Tropical Cyclone Activity

 

Atlantic Ocean: 

Caribbean Sea:  

Tropical Cyclone 02L (Beryl) is located about 330 miles east-southeast of Tulum, Mexico…according to the NHC advisory number 24

CENTER OF BERYL MOVING AWAY FROM THE CAYMAN ISLANDS…STRONG WINDS, DANGEROUS STORM SURGE, AND DAMAGING WAVES EXPECTED ON THE COAST OF THE YUCATAN PENINSULA OF MEXICO BY EARLY FRIDAY

Beryl is moving toward the west-northwest near 18 mph. A westward to west- northwestward motion is expected during the next day or two, taking the core of Beryl away from the Cayman Islands through this afternoon and over the Yucatan Peninsula early Friday. Beryl is expected to emerge over the southwestern Gulf of Mexico Friday night and move northwestward across the southwestern Gulf of Mexico on Saturday.

Reports from Air Force Reserve and NOAA Hurricane Hunter aircraft indicate that maximum sustained winds are now near 115 mph with higher gusts. Beryl is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Weakening is forecast during the next day or two, though Beryl is forecast to remain a hurricane until it makes landfall on the Yucatan Peninsula.

Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 160 miles.

A fast-moving tropical wave located over the eastern Caribbean Sea is producing some disorganized shower and thunderstorm activity. Development, if any, of this system should be slow to occur while it moves quickly westward to west-northwestward at 20 to 25 mph across the Caribbean Sea through this weekend. The system is forecast to cross the Yucatan Peninsula and enter the southwestern Gulf of Mexico by early next week where some development could occur. Gusty winds and locally heavy rainfall are possible across portions of the Greater Antilles over the next few days.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…low…20 percent

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific:

Tropical Cyclone 01E is located about 175 miles southwest of Manzanillo, Mexicoaccording to the NHC advisory number 1

FIRST TROPICAL DEPRESSION OF THE EASTERN PACIFIC SEASON FORMS… …EXPECTED TO BE A SHORT-LIVED SYSTEM

The depression is moving toward the northwest near 9 mph, and this general motion is expected to continue through tonight. A turn toward the west is forecast on Friday and Friday night.

Maximum sustained winds are near 35 mph with higher gusts. Little change in strength is forecast today, followed by gradual weakening tonight and Friday. The system is forecast to become a remnant low by Friday night.

Interesting:  The Race to Save Glacial Ice Records Before They Melt Away

When Margit Schwikowski helicoptered up to Switzerland’s Corbassière glacier in 2020, it was clear that things weren’t right. “It was very warm. I mean, we were at 4,100 meters and it should be sub-zero temperatures,” she says. Instead, the team started to sweat as they lugged their ice core drill around, and the snow was sticky. “I thought, ‘This has never happened before.’”

What Schwikowski couldn’t see yet, but would find later in the lab, is that it wasn’t just the surface that was affected: Climate change had penetrated the ice and trashed its utility as an environmental record. Warming weather had created meltwater that trickled down, washing away trapped aerosols that researchers like her use as a historical record of forest fires and other environmental events. Because of the melt, she says, “we really lose this information.”

Schwikowski, an environmental chemist at the Paul Scherrer Institut near Zurich, is the scientific lead for the Ice Memory Foundation, a collaborative group that aims to preserve glacial ice records before climate change wrecks them.

Their goal is to get cores from 20 glaciers around the world in 20 years, and, starting in 2025, lock them away for long-term storage in an ice cave in the Antarctic — a natural freezer that will hold them at close to minus 60 degrees F.

Since the program’s start in 2015 they have taken cores from eight sites, in France, Bolivia, Switzerland, Russia, Norway, and Italy. But the core attempted from Corbassière was a failure — and has the team wondering if they are already too late.
