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

It’s mostly clear here in Maui County early this morning before sunrise, with the usual clouds along the windward sides and over the West Maui Mountains. The low temperature here at my place was a cool 50.5 degrees.

Weather Wit of the day:  Rainy Opening Day – Ooze on first

 

Hawaii’s Broad Brush Weather Overview:  High pressure north of the islands will maintain breezy easterly trade winds. Clouds and showers will favor windward areas, particularly at night and during the early morning hours, with a few showers occasionally spilling into leeward communities due to the strength of the trades. Some shower development is also expected each afternoon over Kona slopes of the Big Island. A disturbance aloft could bring an increase in shower coverage and intensity late next week.

Hawaii’s Weather Details:  A high is centered well north, and is driving moderate to breezy trade winds across the island chain. Imagery shows partly cloudy conditions across much of the state, with a bit more cloud cover affecting some windward and mountain areas, as well as portions of leeward Big Island. Radar imagery shows scattered showers moving into windward slopes and coasts, with a few showers spilling leeward at times over the smaller islands, and affecting the leeward slopes south of Kona on the Big Island.

High pressure will shift eastward to the north of the state today, then strengthen as it moves northeastward and further away from the islands tonight through early next week. This will maintain breezy trades across the island chain. The trades may ease slightly during the middle to latter part of next week, as a couple of cold fronts pass by to the north of the state.

Fairly typical trade wind weather will prevail, with showers favoring windward areas, particularly at night and during the early morning hours. A few showers will occasionally reach leeward communities due to the strength of the trades, and some leeward shower development is expected each afternoon on the Big Island. A disturbance aloft could increase shower coverage and intensity across the islands late next week.

Hawaii’s Marine Environment:  A surface ridge north of the area will continue to bring fresh to strong easterly trades through early next week. A Small Craft Advisory, now in effect through Sunday afternoon, has been expanded to include most Hawaiian waters with the exception of windward Kauai and windward Big Island. The advisory will likely need to be extended through early next week as these fresh to strong trades persist.

Surf along south-facing shores will trend up as a new, long period, south southwest swell builds. Small forerunners have begun to show up at the near shore buoys with a 17 second period. This swell is forecast to fill in, peaking tonight into Sunday, then slowly decrease into early next week. Surf heights may approach low end advisory criteria during the peak of the event.

Surf along east-facing shores will remain rough and choppy due to the persistent trade winds.

Surf along exposed north-facing shores will remain small with mainly shorter period north swell. A mix of small north and northwest swells will maintain small surf along north-facing shores.

Interesting:  Vanishing Vultures Could Have Hidden Costs for the Planet

Falling vulture numbers in the Americas could have serious implications for public health and ecosystems, new research has found.

A first-of-its-kind study conducted in Costa Rica has revealed that pig carcasses take twice as long to decompose if vultures are not present to provide their rapid recycling services.

Notably, other scavengers do not fill the void left by the absence of the birds, except for flies, whose numbers were seen to double with the reduced competition.

The study, published in Ecology and Evolution, and led by scientists in the Centre for Ecology and Conservation at the University of Exeter, Cornwall, and OSA Conservation in Costa Rica, shines a light on the underappreciated role played by vultures. It also raises questions and concerns about the potential impact of increased fly populations on the environment and human health.
