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.

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

 

Hawaii’s Weather Highlights…as of Saturday morning: 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 during this time, 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 our area.

Weather Narrative…as of Saturday morning: Radar indicates scattered light showers across windward and mauka areas, and the open waters offshore. Some continued increase in coverage is expected this morning, but showers will weaken outside of windward areas this afternoon.

Mid level ridging will remain centered overhead through the middle of next week. Surface high pressure northwest of the islands today will slowly slide east to our northeast Sunday night. An upper level low will approach from the northwest Tuesday. In addition, a band of low level moisture associated with an old frontal boundary will move across the state from the east and northeast. These features will lead to an increased chance for showers mid-week…with even leeward areas seeing a few showers at times.

The upper low will dissipate as it finally reaches Hawaii around Thursday. Weak, broad ridging may build somewhat to our west late week and next weekend. This flow pattern may allow for more old fronts to pass through the state, but the timing of these is of low confidence at this range.

Fire Weather: Fire weather conditions will remain below critical, limited by wind speeds for most areas and by higher minimum humidity levels for the higher elevation zones that reach wind thresholds. Wind speeds will increase into the moderate to breezy levels later today, lasting into early next week. Temperature inversion heights near Maui and the Big Island will range from 6,500 to 7,500 feet elevation today.

Marine Conditions…as of Saturday morning: High pressure north of Hawaii will drive fresh to locally strong trade winds today. A new high pressure system building north of the islands will cause trade winds to strengthen back to strong levels for most waters by tonight. Therefore, the Small Craft Advisory (SCA) remains in effect for the typical windy waters near Maui County and the Big Island today, with an expansion to cover all coastal waters tonight.

Winds will diminish somewhat on Sunday as the high shifts quickly to the northeast, but a new north swell will bring high seas to exposed waters, which will prompt an extension of the SCA for at least some zones beyond just the typically windy ones (likely all windward zones). Next week will see continuing fresh to strong trades with some minor fluctuations each day.

A moderate, medium-period north-northwest swell will continue to decline today. A new small, long-period north-northwest swell will help support small surf through the day, before the arrival of a more significant north swell late Saturday night. This moderate, long- period north swell will push surf to near advisory levels on Sunday for north and west-facing shores.

This swell, at around 350 degrees, looks to peak Sunday afternoon and evening, which may lead to surges into north-facing harbors. Surf to at least moderate levels, along with harbor surge potential, will last into Monday, before the swell really begins to fade on Tuesday. A small to moderate northwest swell is then possible by next weekend.

Surf along east-facing shores will remain rough and choppy due to the fresh trade winds and increase tonight into Sunday with strengthening trades.

South shore surf will stay tiny to small for the next few days, then a small long-period swell could boost surf heights towards the end of next week.

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.
