~~~ 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.

535am, it’s mostly clear early this morning here in Kula, with a chilly low temperature of 51.5 degrees at my place.

520pm, yet another pretty typical early summer afternoon, with warm sunshine, and fortunately a refreshing trade wind breeze.

850pm, clear to partly cloudy skies, the breezy trade winds of earlier are now completely calm. The high temperature here at my place today was 81.5 degrees…while the thermometer is now reading 63.1 degrees out on my weather deck.

 

Hawaii’s Broad Brush Weather Overview:  Moderate trade winds will prevail through the weekend, strengthening somewhat early next week. Clouds and showers will favor windward areas, with the potential for increased shower coverage and intensity this weekend, as an upper-level low passes just north of the islands. The low will also bring the potential for thunderstorms, especially over interior Big Island during the afternoons.

Hawaii’s Weather Details:  A stable trade wind weather pattern remains in place, with latest soundings showing a robust subsidence inversion based near 6,000 feet. Satellite, radar and observations indicate that the trade flow immediately upstream of the islands contains little in the way of showers, with an area of increased showery low clouds located about 200-400 miles ENE of the islands. Water vapor imagery shows a well-developed, nearly stationary low aloft centered about 650 miles ENE of the islands.

The forecast suggests that the trade-wind-supporting ridge north of the islands will weaken slightly over the weekend, then strengthen early next week, with trade winds speeds following suit. In the shorter term, the nearby area of increased showers is expected to arrive early Friday, likely fueling a wet period windward through the morning.

The low aloft will move toward the islands beginning Friday, passing north of Kauai Saturday and Sunday. The nearby passage of the low may act to weaken the low-level subsidence inversion, bringing the potential for increased cloud and shower coverage over the weekend, mainly windward. As the low departs to the north early next week, a strong ridge aloft will support increasing stability as trade winds increase and become breezy.

Hawaii’s Marine Environment:  High pressure north of the state will maintain moderate to at times strong trade winds through the weekend. A Small Craft Advisory (SCA) remains in effect for the typically windy waters around Maui and the Big Island, and may be needed at times through the weekend, as winds flirt with SCA levels. The trades look to strengthen back to fresh and strong levels early next week.

A series of south swells will keep south shore surf near the summertime average through the weekend. Surf will lower below normal levels much of next week.

A small northwest swell will fill in, giving a small boost to north shore surf on Friday, then fade out over the weekend. Typical mostly flat summertime conditions will prevail along north facing shores next week.

East shore surf will remain well below normal through the weekend, then trend closer to seasonal levels next week, as the trades strengthen over and upstream of the islands.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

>>> Central Tropical Atlantic:

Invest 95L

Showers and thunderstorms continue to show signs of organization in association with a tropical wave located several hundred miles west-southwest of the Cabo Verde Islands. Environmental conditions appear conducive for additional development, and a tropical depression or tropical storm is likely to form over the next day or two. This system is expected to move westward at 15 to 20 mph towards the Windward Islands. Interests in the Lesser Antilles should monitor the progress of this system.

* Formation chance through 48 hours…high…80 percent
* Formation chance through 7 days…high…90 percent

>>> Eastern Tropical Atlantic:

A tropical wave centered a few hundred miles south-southwest of the Cabo Verde Islands is producing disorganized showers and thunderstorms. Some slow development of this system is possible early next week while it moves generally westward across the central and western tropical Atlantic at 15 to 20 mph.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…20 percent

Caribbean Sea:  There are no active tropical cyclones

Gulf of Mexico:   There are no active tropical cyclone

>>> Western Caribbean/Southwestern Gulf of Mexico:

Invest 94L

A broad area of low pressure over the western Caribbean Sea is producing widespread but disorganized shower and thunderstorm activity while it moves west-northwestward at around 15 mph. Some development of this system is possible over the northwestern Caribbean Sea or over the southwestern Gulf of Mexico during the next few days.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…low…30 percent

Northeastern Pacific: There are no active tropical cyclones

>>>  Tropical cyclone formation is not expected during the next 7 days

Here’s the link to the National Hurricane Center (NHC)

North Central Pacific:  There are no active tropical cyclones

>>>  Tropical cyclone formation is not expected during the next 7 days

Here’s the link to the Central Pacific Hurricane Center (CPHC)

Northwest Pacific Ocean:  There are no active tropical cyclones

Southwest Pacific Ocean:  There are no active tropical cyclones

North and South Indian Ocean:  There are no active tropical cyclones

Arabian Sea:  There are no active tropical cyclones

Interesting:  Iceland’s Volcano Eruptions May Last Decades, Researchers Find

Iceland’s ongoing volcanic eruptions may continue on and off for years to decades, threatening the country’s most densely populated region and vital infrastructure, researchers predict from local earthquake and geochemical data.

The eruptions on the Reykjanes Peninsula have forced authorities to declare a state of emergency, with a series of eight eruptions having occurred since 2021. This southwestern region is home to 70 percent of the country’s population, its only international airport, and several geothermal power plants that supply hot water and electricity. The most recent eruption in May through June triggered the evacuation of residents and visitors of the Blue Lagoon geothermal spa, a popular tourist attraction, for the third time in more than two months.

Although Iceland sees regular eruptions because it sits above a volcanic hot spot, the Reykjanes Peninsula has been dormant for 800 years. Its last volcanic era continued over centuries however, prompting scientists to predict the renewed volcanism to be the start of a long episode.

Under an hour’s drive from the island’s capital city Reykjavík, the eruptions pose considerable risks for economic disruption, and they leave evacuated communities uncertain of a possible return.
