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.

Glenn’s Thursday comments:  I’m here at home through the winter in upper Kula, Maui

It’s partly cloudy here in Maui County early this morning, with a chilly low temperature of 49 degrees at my place, with the relative humidity 76 percent.

Late morning, breezy southwest kona breezes here in Maui County, we hope this front makes it down over us before it stalls!

1226pm, the clouds associated with this cold front are arriving here on Maui at the moment.

Flash Flood Potential: A band of heavy rain is forecast to develop over the western end of the state on Sunday and persist into next Tuesday. The primary period of interest is the 24 hour period spanning Sunday night through Monday night. At this time, the most likely islands to be affected are Kauai and Oahu. Impacts will be conditional on the position of the heavy rain band and the degree to which it remains stationary. The potential for flash flooding will be further refined in future notices.

Incredible Lava flow Fountain on the Big Island – December 6th

 

Hawaii’s Broad Brush Weather Overview: A cold front will move over Oahu this morning, before stalling and dissipating just north of the Big Island this afternoon and evening. Limited rainfall is expected Friday. Moderate southwesterly kona winds ahead of a stronger front will increase shower potential along leeward areas Saturday. The highest potential for heavy rainfall will develop over the western end of the state Sunday through next Tuesday.

Hawaii’s Weather Details: Satellite and radar imagery shows a band of low level clouds with embedded light to moderate showers, associated with a cold front, moving over the north shore of Oahu this morning. Moderate northerly winds have filled in over Kauai behind the front, with light to moderate southwesterly kona winds ahead of the front. This front will continue to move SE across Oahu this morning reaching Maui County by late morning and early afternoon, with mainly light to moderate showers expected.

The front will stall and dissipate over Maui County, just north of the Big Island this afternoon and evening, and winds will ease to light speeds allowing land breezes to develop overnight. Dewpoint temperatures will dip in the upper 50s tonight around Kauai and Oahu, as drier more stable air filters in behind the front.

Friday’s winds are expected to swing northeast over the western half of the state, with a light southerly surge developing over the eastern half of the state. Lingering moisture from the front along with afternoon sea breezes could trigger a few showers along leeward and interior areas, especially around Maui County.

Saturday will find moderate southerly winds developing across the state as a stronger front approaches from the northwest. By Saturday night, a pre-frontal convergence band may set up over the western half of the state, increasing chances of showers. There appears to be potential for a thunderstorm or two during this time, mainly near Kauai and south waters of Oahu.

Sunday through Tuesday forecasts remains on track. The associated band of heavy rain with a surface low will settle somewhere over the western end of the state Sunday night through Monday night. The parent upper level trough will remain rather progressive, suggesting a 24-36 hour type of event.

Upon the departure of supporting upper dynamics on Tuesday, the surface low will move far north of the state and weaken, leaving an orphaned frontal moisture band over the area through mid-week, maintaining lingering showers over the area. Southerly winds will prevail throughout this time, keeping leeward areas in the game for rainfall for at least the next week.

Blocking high pressure over the Aleutian Island chain of Alaska will continue a southward-displaced Pacific jet stream. This ensures at least some potential for more active weather continuing for the foreseeable future.

Fire weather:  Conditions will remain below critical fire thresholds into the weekend. Inversion heights slope from 9,000 ft near Kauai to 6,000 ft over the Big Island. Expect inversion heights to increase ahead of a front and will settle and dissipate near Maui County. Inversion heights should level out to near 6,000 ft behind the front and as the front dissipates tonight into Saturday.

Hawaii’s Marine Environment: A weakening cold front that has moved through Kauai will slowly advance east across the Oahu and Maui County nearshore waters. Gentle to moderate northerlies will occur in the wake of the front, with light southwesterly winds downstream of the front. The front is forecast to dissipate in the vicinity of Maui County by early Friday morning. Another front will reach the nearshore waters late Saturday into Sunday morning. Light southeasterlies will veer more southwesterly Saturday, as the front approaches, becoming more westerly. Numerous showers with locally heavy rain and isolated thunderstorms are possible in association with this front Saturday night into early next week.

Wednesday’s moderate size, medium period northwest swell was reinforced by a north-northwest swell and has been peaking. Surf along many north and west-facing shores will remain elevated. This swell will slowly decline from this tonight through Friday. Another moderate, long period northwest swell generated from a developing gale low just northwest of the offshore waters late Friday, will move through the islands Sunday and Monday. This swell should produce advisory level surf Sunday afternoon through Monday morning.

South facing shores, especially southwestern exposures on Kauai and Oahu, may receive a moderate wind swell chop this weekend from increased southwest kona winds ahead of an approaching front.

Interesting: A New ‘Hypertropical’ Climate Is Emerging in the Amazon

Unprecedented hot drought conditions are becoming more common, exposing trees to deadly stress and reducing the region’s ability to absorb anthropogenic carbon dioxide.

The Amazon rainforest is slowly transitioning to a new, hotter climate with more frequent and intense droughts — conditions that haven’t been seen on Earth for tens of millions of years.

The conclusions come from a new study led by the University of California, Berkeley, involving a large team of national and international scientists.

If society continues to emit high levels of greenhouse gases, the researchers predict that “hot drought” conditions could become more prevalent across the Amazon by 2100, occurring even during the wet season. This could lead to widespread tree dieoffs and impair Earth’s ability to deal with increasing levels of atmospheric carbon dioxide, since tropical forests worldwide absorb more human carbon emissions than any other biome. Recent reports found an increase in atmospheric carbon dioxide after severe droughts in the Amazon, showing that weather in the tropics has a measurable impact on the planet’s carbon budget.
