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.

Hawaii Weather Narrative

Glenn’s Saturday comments:  I’m with my friend Bob here at our vacation rental at Sea Ranch, Sonoma County, CA on a working vacation.

439am HST, it’s partly cloudy this morning in coastal Sonoma County, the low temperature was 46.5 degrees.

1245pm, partly cloudy with a few showers this morning, although it’s trended drier this afternoon…61.1 degrees

314pm HST, the sunset this evening here on the coast was spectacular, with the middle level altocumulus clouds lit up as if they were on fire.

Fun Fact: Great Horned Owls are the only birds that regularly eat Skunks

The breaking waves are HUGE here at Sea Ranch!!!

 

Interesting Weather Blog: Mauka Showers…Hawaii Rainfall Patterns During Recent El Niño Events

 

Hawaii’s Weather Highlights…as of Saturday afternoon: Surface high pressure northwest of the Hawaiian Islands will slowly slide east over the next several days. Passing showers are possible over windward and mauka areas, mainly during the overnight to early morning hours. The next best chance for statewide rainfall should arrive Tuesday and Wednesday, as increased low level moisture arrives with an old cold front drifting into out area.

Weather Narrative…as of Saturday afternoon: Radar shows scattered trade showers moving west extending mainly from Molokai to Kauai County. Numerous showers are making it past windward areas and into leeward areas. This is expected to continue overnight before decreasing Sunday. Winds have weakened slightly, now averaging 5 to 15 mph with the windy areas gusting 20 to 30 mph. An upper level ridge will remain centered on the state through Tuesday afternoon.

After that, a weak upper level trough will move in from the west and stay close to the islands into next weekend. At the surface, a large high will move east through Monday. A new high will temporarily take it`s place Tuesday, before replaced yet again by a third high late next week. Bottom line is that there will be high pressure to the north, and trades will stay with us through the next 7-days.

A decaying old front will move through Monday afternoon through Monday night, bringing an increase in showers. Moisture from this feature is forecast to stall near the Big Island into Tuesday. There may be another brief increase in moisture from a similar feature late next week, but models are not good at timing these types of things that far in advance.

Therefore, apart from the aforementioned increase Monday into Monday night, expect typical trade showers, mainly impacting windward and mauka areas, through the coming week. Wind speeds will be fairly normal for this time of year.

Fire Weather: Moderate winds and typical humidities will be with us for the next several days, keeping fire weather from reaching critical thresholds. Temperature inversion heights near Maui and the Big Island will range from 5,000 to 6,500 feet elevation through Sunday.

Marine Conditions…as of Saturday afternoon: Fresh to locally strong trade winds will increase tonight as a strong high builds far north of the islands. The Small Craft Advisory (SCA) has been expanded to all waters to account for the strengthening trades. Winds will diminish gradually late Sunday and Monday as the high moves to the northeast, but a new north swell will push combined seas above the threshold for exposed waters, likely prompting an extension of the SCA for most zones. Expect moderate to locally strong trade winds to require a SCA for the typically windy waters Tuesday through the remainder of the week.

A small north-northwest swell will hold, followed by a moderate, long-period north swell building on Sunday. The north swell (350 to 010 degrees) will produce surf near High Surf Advisory thresholds along north-facing shores, as well as some exposed eastern shores, on Sunday afternoon into Monday morning, and a Marine Weather Statement has been issued to highlight surges in north-facing harbors, mainly at Kahului and Hilo Harbors. The north swell will gradually decline late Monday through Wednesday. A tiny pulse of northwest swell will be possible late next week, followed a moderate swell next weekend.

Rough surf along east-facing shores will remain above seasonal average over the next couple of days due to elevated trade wind swell and some wrapping north swell. East shore surf is expected to be around seasonal average Tuesday through the rest of the week. Mainly small background level surf will persist along south- facing shores through much of the week, though a small long-period swell will be possible on Friday.

Interesting: 
Earth’s ‘Core Carbon’ May Have Come From the Far Reaches of the Solar System

A new study suggests that most of Earth’s carbon originated in the outer solar system and didn’t arrive here until the late stages of planetary development.

The study, led by researchers at Yale and Columbia, is based upon an analysis of magma droplets called “melt inclusions” from historic volcano eruptions in Hawaii, including the Keanak?koi eruptions from 1500 to 1840 and the K?lauea Iki eruption in 1959.

Melt inclusions are bits of molten rock caught inside crystals that form in magma. Each droplet is something of a message in a bottle — a snapshot of what the magma looked like when it was deep within the Earth.
