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 Monday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good Monday wherever you happen to be spending it.

It’s clear and calm, with a chilly low temperature of 49 degrees according to my outside temperature sensor.

What is a Black Moon:

If there are two Full Moons in a calendar month, the second is called the Blue Moon.

If there are two New Moons in a calendar month, the second is called the Black Moon.

 

Hawaii’s Broad Brush Weather Overview:  Typical trade wind weather is expected for most of this week, with moderate to breezy wind speeds and scattered showers focused over windward and mountain areas primarily during the overnight and morning hours. The exception is Tuesday into Wednesday, when a plume of moisture is forecast to move in from the east, increasing windward shower activity. Trades will weaken Friday into the weekend.

Hawaii’s Weather Details:  Surface high pressure remains centered far northeast of the state, driving moderate to locally breezy easterly trade winds, with a mid to upper-level trough just east of the Big Island. The latest satellite and radar imagery shows the band of enhanced low clouds and showers near Kauai and Oahu yesterday evening, has weakened and shifted just north of Kauai. There is also a small area of showers moving into windward Big Island, but mostly isolated clouds and showers elsewhere around the state. Overnight rainfall totals have been mostly in the quarter to half inch range for Kauai, with totals remaining minimal elsewhere, owing to a fairly shallow low-level moisture pool.

Through the day today, we should return to our typical fair trade wind weather, with moderate to breezy trade winds and isolated to scattered showers over windward and mauka areas. On Tuesday, a plume of moisture will move in from the east, which should give a boost to shower activity over windward and mountain areas of Maui County and the Big Island during the day. The rest of the islands should see an increase in windward showers Tuesday night into Wednesday morning, as the plume continues westward and lingers around Kauai. A dry air mass will follow on Wednesday.

Thursday night into Friday, trades will begin to weaken and veer out of the southeast as a cold front approaches the state from the northwest. Friday should be a transition day, with light southeast flow over the western half of the state and moderate to locally breezy east to east-southeast winds over the eastern half. Expect a light and variable wind pattern with mostly fair weather for the weekend.

A hot spot over Halemaumau Crater on the Big Island continues to be seen on infrared satellite imagery. The University of Hawaii Vog Model shows that SO2 emissions should remain confined to portions of the Big Island and adjacent waters to the west and southwest through most of this week. However, vog will likely increase across the rest of the state Friday through the weekend as the trades weaken and veer out of the southeast.

Fire weather:  No critical fire weather conditions are expected for the next 7-days. The trade winds will continue to remain at moderate to locally breezy speeds with relative humidities staying above critical levels through most of this week. Trades should ease by the weekend.

Hawaii’s Marine Environment:  Multiple overlapping northwest swells (300-320) are expected through Friday and beyond. Surf heights will likely reach advisory levels on Thursday, Friday, and possibly into the weekend along exposed north and west facing shores. Surf along south and east facing shores is expected to remain small through the week.

Strong high pressure over the northeast Pacific will hold over the next several days then gradually weaken. So will fresh to strong trade winds across most local waters. The Small Craft Advisory (SCA) for the typically windier waters around Maui County and the Big Island has been extended through Tuesday.

Interesting:  How grocery stores can help protect the climate

Photo of a grocery store fridge full of fruit

At supermarkets, fridges, freezers, and cooling cases connected by miles of piping help keep food fresh. Skilled technicians keep those systems running smoothly.

And those workers can play a critical role in helping supermarkets reduce their climate impact.

Vanzo: “Refrigeration has been identified as one of the leading global opportunities to address climate change and reduce emissions.”

Morgan Vanzo of the North American Sustainable Refrigeration Council says most fridges and freezers use refrigerants called HFCs. They’re potent global warming gases.

There are alternatives to HFCs that are better for the climate. But she says to make the switch, a store must replace its entire system.

Vanzo: “And it requires a robust workforce that’s ready to not only install these systems but service them.”

She says refrigeration technicians are already in high demand – and there are few who are trained in these more sustainable technologies.

So her group works with community colleges and trade schools to help recruit more people into the field – and offers workshops and trainings to prepare technicians to work with less polluting systems.

So they can help supermarkets transition to a climate-friendly future.
