Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) 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 home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear to partly cloudy here in upper Kula early this morning, while my low temperature was 53 degrees.

Weather Wit of the day:  Wind chill Factor – brrr index

 

Hawaii’s Broad Brush Weather Overview:  Mostly dry and stable conditions will persist into the weekend, with light east to southeast winds continuing. Showers will remain limited, generally light with minimal accumulation due to the overall dry and stable environment. Expect showers to favor windward and southeast-facing slopes overnight through the early morning hours, with only a few developing over interior and leeward areas in the afternoons where sea breezes form.

Rain chances may increase early next week as a deep low pressure system west of the state draws moisture northward into the islands, particularly over the western end of the state.

Hawaii’s Weather Details:  Model guidance remains in decent agreement through the weekend, showing low-level winds holding from the east-southeast, as the surface ridge lingers near the islands. Aloft, guidance suggests a buckle in the previously zonal jet stream, with a broad cutoff low forming by the weekend. This setup will likely lead to reinforcing a more stable and suppressed environment.

As a result, mostly dry and stable conditions are expected to persist, with only light to moderate showers favoring windward and southeast-facing slopes overnight through the early morning hours. During the afternoons, sea breezes may lead to some interior and leeward cloud buildups, but any associated showers should remain brief and limited in coverage.

Forecast confidence decreases heading into early next week, due to large differences among the model solutions. However, there is general agreement that deep low pressure to the west of the state will gradually shift eastward, causing the low-level flow to veer out of the south. This evolving pattern could lead to increased moisture being drawn northward, particularly over the western end of the state.

As a result, rain chances may increase, especially if the deeper moisture axis shifts farther eastward. How far east this moisture axis shifts by mid-week will be the key factor in determining the extent and coverage of rainfall across the state.

Hawaii’s Marine Environment:  A surface ridge will remain near or just north of the islands through the weekend, with light to moderate east-southeast winds prevailing. Diurnal land and sea breezes will dominate the flow over nearshore waters sheltered from the large-scale flow. Early next week, deep-layer low pressure far northwest of the islands may bring increased south-southwest kona winds.

The large scale pattern will be supportive for the development of relatively small north-northeast swells for the islands over the next week or so. In the short term, the fetch associated with a storm-force low near WA/OR will send a north-northeast swell toward the islands into Sunday, with the swell likely peaking on Friday. A small west-northwest swell may also arrive over the weekend. More medium-period north swell is anticipated next week. Small, long-period south-southwest swells are expected to provide small surf to south facing shores into next week.

Interesting:  Ecosystem Disrupted Following the Disappearance of Great White Sharks, New Study Finds

A new study published in the journal Frontiers in Marine Science, has uncovered evidence of far-reaching ecosystem consequences following the disappearance of Great white sharks (Carcharodon carcharias) from False Bay, South Africa. The research, conducted by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science, spans over two decades and documents cascading ecological disruptions, underscoring the crucial role apex predators play in maintaining ocean health.

Using a combination of long-term boat-based surveys of shark sightings, citizen science observations on Cape fur seals, and Baited Remote Underwater Video Surveys (BRUVS) of fishes and small sharks, the study provides evidence that the absence of Great white sharks has triggered significant shifts in the marine food web.

“The loss of this iconic apex predator has led to an increase in sightings of Cape fur seals and sevengill sharks, which in turn has coincided with a decline in the species that they rely on for food,” said Neil Hammerschlag, Ph.D., the study’s lead author. Hammerschlag conducted the research while at the Shark Research and Conservation Program at the University of Miami Rosenstiel School. “These changes align with long established ecological theories that predict the removal of a top predator, leads to cascading effects on the marine food web.”
