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 Wednesday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s mostly clear here in Maui County this morning, with low clouds along the windward sides and some high level cirrus clouds…those high cirrus lit up a beautiful pink at sunrise! The low temperature here at my place was 53 degrees.

Weather Wit of the day:  Disgust – Dis sudden increase in de wind

 

Hawaii’s Broad Brush Weather Overview:  Breezy and mostly dry trade wind weather will persist into Thursday. A slight increase of shower coverage is expected Thursday into Friday. Light to moderate trade winds are expected over the weekend with mostly dry conditions. Chances of showers look to increase early next week.

Hawaii’s Weather Details:  Strong high pressure far northeast of the state will maintain breezy trade winds into Thursday. Scattered light to moderate showers will continue to ride in with the trade winds, and will mainly be focused over windward and mountain areas, with a few showers making their way to leeward areas as well, due to the breezy trades especially tonight into early Thursday morning.

Satellite imagery shows a weak upper level low located just west of the state, sending some mid to high level clouds streaming over the state today into Thursday.

As the high weakens far northeast of the state Thursday, trade winds will gradually weaken to moderate levels by Friday. The weak upper level trough will slide over the state, that could help enhance some showers embedded in bands of clouds riding in with the moderate trades mainly along windward and mountain areas.

Drier conditions are expected over the weekend as a small upper level ridge builds briefly overhead. Light to moderate winds will hold over the weekend into early next week, which could allow for sea breezes to develop each afternoon along select leeward areas, increasing clouds and a slight chance of showers before clearing out overnight as land breezes develop.

Chances of showers look to increase early next week, as another upper level trough of low pressure forms west of the state, increasing low level moisture.

Hawaii’s Marine Environment:  Moderate to locally strong trade winds will gradually ease Thursday and could become gentle to locally fresh as early as Friday, then hold into early next week as high pressure to the far northeast remains nearly stationary and weakens. The Small Craft Advisory (SCA) for the usual windier waters and channels around Maui County and the Big Island has been extended through Thursday, as locally strong trade winds hold.

A tiny to small, inconsistent long period southwest swell has arrived and will continue to fill in along south facing shores, producing small surf. A larger swell from a fetch near New Zealand is slated to bring a moderate, long period south-southwest swell as early as Friday. This swell is expected to peak Saturday into Sunday, potentially near High Surf Advisory (HSA) criteria before slowly fading into early next week.

East-facing shore surf will remain choppy due to the moderate trade winds locally and upstream. A combination of a strong high pressure to the far northeast, and a low near California earlier this week has produced the potential for a moderate, medium period northeast swell Thursday afternoon, peak Friday, and decline through the weekend.

Surf along north facing shores will remain small, albeit with some wrap from the northeast swell.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7-days.

Gulf of Mexico:  There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7-days.

Northeastern Pacific:   There are no active tropical cyclones

South of Southern Mexico

>>> Satellite surface wind data indicate than a broad area of low pressure has formed a few hundred miles offshore of the coast of southern Mexico and is producing disorganized showers and thunderstorms. Environmental conditions are expected to be conducive for gradual development of this system, and a tropical depression is likely to form over the weekend while it moves generally westward to west-northwestward around 10 mph.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…high…80 percent

Interesting:  Salamanders Suffering from Rising Temperatures

Habitat loss, diseases, pollution, and climate change are already massively affecting amphibians – frogs, salamanders, and the caecilians native to tropical regions. The new study from the Institute for Ecology, Evolution and Diversity shows that extreme weather events serve as an additional stress factor, further intensifying this crisis. For this purpose, the scientists analyzed global weather data from the past 40 years.

They compared regions with significantly increased heat waves, droughts, and cold spells with the geographical distribution of more than 7,000 amphibian species and their threat status on the „Red List.“ The Red Lists are being published since 1964 by the International Union for the Conservation of Nature and Natural Resources (IUCN) and are considered an important tool for assessing the threat status of animal, plant, and fungal species worldwide.

Critical Interaction of Various Factors – The results are clear: where heat waves and droughts have increased, the threat status of amphibians on the Red List has also significantly deteriorated since 2004. „Amphibians‘ dependence on temporary wetlands for breeding makes them particularly vulnerable to droughts and temperature shifts that causes their breeding grounds to dry prematurely,“ explains Dr. Evan Twomey, lead author of the study. “Our analyses show the direct connection between the increase in extreme weather events and the decline of amphibian populations.“
