Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. 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 Aloha Friday comments: I’m here at my friend Linda’s place in Corte Madera, CA

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

353am, it’s a clear to partly cloudy morning, with a low temperature of 50 degrees…with breezy conditions.

I’m going to play Pickleball in Mill Valley this morning, and am hoping its not too windy.

 

Hawaii’s Broad Brush Weather Overview:  Strong trade winds will gradually ease and veer toward the east-southeast through early next week. Plumes of moisture will produce passing showers across windward and mountain areas through Saturday.

A drier weather pattern is expected Sunday into early next week, with light to moderate east to east-southeast winds. Winds should be light enough for sea breezes to develop during the day and land breezes at night, especially early next week.

Hawaii’s Weather Details: A high far northeast of the state is currently producing gentle to locally windy trade winds across the state. Latest satellite and radar imagery shows low scattered clouds and showers riding in with the trade winds along windward areas with some of these showers spilling over to leeward locations of the smaller islands.

There is also a veil of thin high clouds filling in from the west. Low clouds and showers may clear a little this afternoon, but will soon be followed by another plume of moisture later this afternoon into Saturday. Showers will primarily be focused over windward areas with some spillage to leeward locales of the smaller islands. Rainfall amounts should remain light to moderate, due to stable conditions aloft.

An area of low pressure will develop along a front well northwest of the state, and is expected to continue to develop through Saturday before shifting northeast. This set up will shift winds slightly to the east-southeast on Saturday for the western half of the state, allowing for a hybrid wind pattern over the weekend with land/sea breezes developing over leeward areas of the smaller islands. There will still be an easterly component of the winds producing a moderate to locally breezy showers over windward areas, especially for the eastern half of the state.

A trough of low pressure extending from the low pressure system will develop northwest of the island chain early next week, as the low tracks far north of the state of Hawaii early next week. This will further ease winds locally, allowing for a more dominate land/sea breezes pattern to occur.

The surface trough and associated upper level trough will provide a conveyor belt, drawing slightly above normal moisture levels over the state. These features could allow for taller clouds to develop each afternoon, with the seas breezes, especially near Kauai. However, rainfall totals are not expected to be significant. Look for clouds and chances of showers to diminish each night with the land breeze.

Marine Environmental Details:  A high northeast of the state will slowly drift eastward over the next several days. Meanwhile, a new low is forecast to develop northwest of Hawaii. Strong east-northeast trade winds are expected through channeled areas, but should gradually weaken and shift to the east-southeast by Saturday in response to the approaching low.

Surf heights will remain below advisory thresholds for all shores. Multiple small northwest swells are expected now through Saturday night. Expect these swells to produce small surf along north and northwest facing shores.

A small southerly swell will lead to a slight bump in surf heights along south facing beaches. Strong trade winds will continue to produce choppy, rough surf along east facing beaches. Smaller, smoother surf is expected along east facing shores starting Saturday and continuing into next week.

Interesting:  A technology in road markers could cool cities

 

A technology in road markers could cool cities by up to 20°C

Engineers are using retroreflector technology—based on prisms and reflective materials—to direct sunlight back into the sky and out of the urban canyon.

Heat-related deaths around the world are climbing up as more frequent, longer-lasting extreme heatwaves become a harsh reality due to climate change. Heat deaths are projected to increase by 370 percent if global warming continues at its current rate.

This heating effect is more pronounced in dense cities because of the urban heat island effect. But reflecting sunlight back into the sky using the technology found in reflective road signs and bike reflectors could help cool cities down, according to Princeton University engineers.

The technology, called retroreflectors, use a combination of prisms and reflective materials to create a marker that is visible from long distances, even in low-light conditions.

Equipping building walls and roadways with these retroreflective materials could reduce urban temperatures by up to 20°C, they report in the journal Nature Cities. It should also notably improve air temperatures and human skin temperatures.

“More people die from extreme heat in the U.S. than from any other weather-related event,” said Elie Bou-Zeid, professor of civil and environmental engineering. “There’s an urgent need to develop and deploy technologies that can help people stay cool.”
