Hawaii’s MountainsHere’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.

230pm, we’re just now getting our first very light shower here in upper Kula…along with pea soup fog

415pm, it’s a winter-like afternoon here at my place, with the temperature a chilly 62.7 degrees, and the RH is 77%

6pm, it’s 61.3 degrees here in upper Kula, with drizzle and low clouds. It was enjoyable to take my final walk of the day, with my raincoat on in the misty conditions.

Flash Flood Potential: The forecast remains on track. Expect increasing shower and thunderstorm chances for Kauai and surrounding waters on Saturday night, then spreading eastward to include Oahu and Maui County as well on Sunday. The best chances for heavy rain and thunderstorms will be Sunday night through Monday night. Lingering moisture will remain in place, however, with an overall wetter period through at least next Wednesday.

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

 

Hawaii’s Broad Brush Weather Overview: A cold front will stall and dissipate north of the Big Island, maintaining shower chances for Maui County through the night. Limited rainfall is expected Friday. Moderate southwesterly kona winds ahead of a stronger cold front will increase shower potential along leeward areas Saturday. The highest potential for heavy rainfall and thunderstorms will develop over the western end of the state Sunday through next Tuesday.

Hawaii’s Weather Details: Satellite and radar imagery shows that the band of low level clouds and embedded light to moderate showers, associated with a weakening front moving over the state, is currently located across primarily the islands of Maui County. Rainfall amounts have been modest at best, however, with the most rain falling over portions of Oahu and Molokai (generally receiving up to a little more than half of an inch in the heaviest spots over the past six hours).

Meanwhile, moderate northerly winds have filled in behind the front, with increasingly stable and dry post-frontal conditions observed for Kauai. Expect a drying trend for Oahu tonight, though shower chances will continue for Maui County, as the front stalls and dissipates north of the Big Island. Additionally, dewpoint temperatures will dip in the upper 50’s tonight around Kauai and eventually Oahu, as drier more stable air filters in behind the front.

Winds will ease to light speeds tonight as the front dissipates, allowing land breezes to develop. For the Big Island summits, strong southerly winds are mixing down to summit level. These should gradually decrease throughout the night as well, however. In the meantime, a Wind Advisory has been issued for borderline advisory-level winds on the Big Island summits through tonight.

On Friday, lingering moisture leftover from the front, along with afternoon sea breezes, could trigger a few showers along leeward and interior areas, especially around Maui County. Moderate southerly winds will develop across the state on Saturday, as a stronger front approaches the islands from the northwest. By Saturday night, a pre-frontal convergence band is expected to set up over the western half of the state. This will increase chances for showers and thunderstorms, particularly near Kauai and its surrounding waters for Saturday night.

A band of heavy rain and potential thunderstorms associated with a surface low, will settle somewhere over the western end of the state Sunday through Monday night, with the heaviest rainfall potential Sunday night into Monday. Upon the departure of supporting upper dynamics on Tuesday, the surface low will move far north of the state and weaken, leaving a frontal moisture band over the area through at least mid-week. Expect lingering showers over the the islands through at least Wednesday. Southerly winds will prevail throughout this time.

Fire weather:  Conditions will remain below critical fire thresholds into the weekend. Increasing shower chances associated with an incoming front, combined with light to moderate winds, will prevent us from reaching critical fire weather thresholds over the next several days.

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.
