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

It’s mostly clear with just a few clouds here in Maui County early this morning, with a low temperature of 56.5 degrees.

Weather Wit of the day:  Tide – A shore thing

 

Hawaii’s Broad Brush Weather Overview:  A weak trough over Maui County, will continue to slowly drift northward as a shallow cold front approaches the islands from the northwest. These two systems will merge near Kauai and Niihau tonight, producing widespread showers over the Garden Isle. Breezy and cool northerly winds will fill in behind the front, as it moves down the island chain, stalling near the Big Island by Tuesday.

Showers will favor windward areas and all areas within the passing frontal cloud band. A very wet weather pattern unfolds from Wednesday night through Friday morning, with unstable southerly kona winds bringing potential for heavy rain, with strong gusty winds, and strong thunderstorm threats. This fast moving kona low weather pattern may produce statewide severe weather threats during this time period.

Hawaii’s Weather Details: Satellite imagery shows a few thunderstorms developing in the coastal waters just west of the Big Island along the leeward wind convergence plume. These thunderstorms will likely diminish later this morning. Farther northwest of the state a cold front continues to approach the island chain.

For today, expect light to moderate trade winds to continue for most areas, with some shower activity mainly favoring the windward and mountain areas. Wetter trends are expected by tonight, as a cold front combines forces with the weak low level trough near Kauai lasting into Monday. Expect widespread showers developing across the Garden Isle lasting into Monday morning. Breezy and cool northerly winds will quickly move in with decreasing shower trends after this front passes through each island.

The arrival timing of the showers are set to reach Oahu and all the islands in Maui County by Monday morning, then spread to the Big Island by Monday afternoon. The cold front will weaken as it passes through each island. Showers along the frontal band will be more numerous near Kauai, with lesser amounts of rainfall expected to reach the eastern islands with this event. Thunderstorms may develop just north of the island chain along the passing frontal boundary. The front will stall and diminish near the Big Island by Wednesday, with a brief period of decreasing shower trends in the forecast.

By Wednesday night the weather conditions are trending towards a significantly wetter and unstable pattern, as a kona low weather system moves through the Hawaii area from Wednesday night through Friday morning. Southerly to southwesterly kona winds will pull up unstable tropical moisture northward into two passing cold core lows. Severe weather threats are increasing with this system, as the latest models are improving their consistency during this time period.

Threats appear to be statewide from a 12 to 24 hour time period for each island, with rising threats for heavy rain with storm total rainfall amounts in the 1 to 2 inch range, locally higher rainfall totals are possible, some snowfall and warning level winds are forecast over the Big Island Summits, strong gusty downsloping winds will likely impact some communities along northeast facing mountain slopes, and last but not least the growing potential for severe thunderstorm activity.

The outlook for isolated thunderstorms and heavy rainfall threats have expanded statewide. Stay tuned for the latest weather forecast updates with this kona low weather system, as the island by island impacts and severe weather threats will likely evolve over time.

Fire weather:  Wind speeds will remain below critical fire weather thresholds through the middle of the new week. Moisture levels rise swiftly Thursday onward with southerly winds bringing another round of widespread rainfall in the forecast for all islands.

Hawaii’s Marine Environment:  Light to moderate northeast to east winds will continue, as a weak surface ridge remains north of the state. Pockets of fresh breezes are possible over the typically windier waters and channels from Maui County to the Big Island during this time. Fresh to strong northerly breezes are expected over the western end of the state through Tuesday, as a front moves down the island chain. A Small Craft Advisory will be issued for the potential of strong northerly winds and rough seas over the waters surrounding Oahu and Kauai. Uncertainty increases from around mid-week onward, with some models depicting low pressure forming along the stalled frontal boundary in the area.

With a blocking high persisting over the northwest Pacific, the primary swell source will remain predominantly from the north throughout the week. This will feature a mix of rough, short-period wind waves from the strong northerly winds expected locally early in the week, along with medium-period northerly swells. Guidance remains in good agreement, indicating an upward trend from Tuesday through late in the week, due to the potential for a gale- to storm-force low forming well to the north. Surf heights could approach or reach the advisory level for north facing shores Wednesday through Friday if this scenario materializes.

Surf along east-facing shores, not exposed to northerly swells, will remain small each day, due to the lack of local trades and upstream swells.

Surf along south-facing shores will remain around the seasonal average through mid-week, with a mix of short-period southeast swells and occasional background south swells. Uncertainty increases late in the week, with the potential for southerly winds to evolve, which could translate to a brief period of rough, short-period surf.

Interesting:  Progress With New-Look Wind Turbine

A next-generation vertical wind turbine is set to be put on trial south of Adelaide in a novel research collaboration between Flanders University and South Australian start-up company VAWT-X Energy.

Supported by private equity and state and federal funding, the research team has constructed and tested a 6KW prototype to install at a field site on the Fleurieu Peninsula in coming weeks.

The futuristic new design could help to increase the sustainability and energy operating costs of residential, agricultural and light industrial operations close to metropolitan areas, as well as large-scale offshore wind farms.
