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. Here’s the webcam for the (~10,023 feet high) Haleakala Crater 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.

At the Lake – a poem by Mary Oliver

A fish leaps like a black pin-then-when the starlight strikes its side —
like a silver pin. In an instant the fish’s spine alters the fierce line of rising
and it curls a little-the head, like scalloped tin, plunges back, and it’s gone.

This is, I think, what holiness is: the natural world, where every moment is full
of the passion to keep moving.

Inside every mind there’s a hermit’s cave full of light, full of snow, full of concentration.

I’ve knelt there, and so have you, hanging on to what you love, to what is lovely.

The lake’s shining sheets don’t make a ripple now, and the stars are going off to their
blue sleep, but the words are in place-and the fish leaps, and leaps again from the black
plush of the poem, that breathless space.

 

Hawaii’s Broad Brush Weather Overview…as of Saturday evening: High pressure north of the islands will bring moderate to breezy trade winds through Monday. Wind speeds will weaken Tuesday through Thursday, as a weakening surface trough moves into the state. Southeast winds are expected late next week, with a chance that trade winds return next weekend, as high pressure at the surface strengthens to our north.

Weather Details for the Hawaiian Islands…as of Saturday evening: Radar and satellite show mostly cloudy skies and scattered showers across most windward and many mountain areas, along with the Kona region of the Big Island. Very few showers have made it to leeward areas, but a good amount of cloud cover has moved in from time to time.

Winds were generally out of the northeast at 10 to 20 mph, with a few higher gusts, but some leeward areas had west winds coming in off the ocean. These showers will decrease in the Kona region this evening, but otherwise should continue into the night.

With the upper low to our northeast finally moving away, upper level ridging will be able to strengthen. This will keep moderate to occasionally breezy trade winds with us through Monday, as surface high pressure systems to our NE and NW move east across the Pacific. A weak trough (dying cold front) will move toward the area Monday, and pressure falls associated with its approach will veer winds to southeasterly Monday night.

Light north to northeast winds behind the trough are expected to develop over western islands Wednesday, perhaps reaching as far east as Maui Wednesday night. With light winds Tuesday through Thursday, expect a few more clouds than normal over leeward areas, and perhaps a brief shower.

Winds will then return to southeasterly Thursday and remain that way into next weekend. PW values will be relatively low throughout the next week. Trades may return next weekend.

Marine Environmental Conditions…as of Saturday evening: Trades steadily weaken, becoming light to variable by the middle of next week, as a decaying cold front approaches from the west.

Existing small WNW swell will gradually fade this weekend. Another slightly smaller NW swell is anticipated early next week, in maintenance of elevated surf along N and W shores. Guidance then indicates another long period NW (320) swell arriving late next week. This swell will be generated by a developing low near Japan that is forecast to lift NE toward the Kuril Islands this weekend. Surf along S shores trends up this weekend, as a long period SSW pulse arrives. This swell will peak late Sunday into Monday. As trades steadily weaken, wind waves and trade wind swell will follow with diminishing surf expected along E facing shores during the next several days.

Interesting:  How the Next El Niño Could Lock in a Hotter Climate

The Pacific Ocean is a giant climate cauldron, with a powerful heat engine that affects storms, fisheries and rainfall patterns half a world away, and scientists are watching closely to see if it’s about to boil over.

Their projections suggest the tropical Pacific is simmering toward a strong El Niño, the warm phase of an ocean-atmosphere cycle that can intensify and shift those impacts.

In a world already superheated by greenhouse gases, a strong El Niño during the next 12 to 18 months could permanently push the planet’s average annual temperature past the 1.5 degrees Celsius warming threshold enshrined in scientific documents and political agreements as a turning point for potentially irreversible climate impacts.
