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 Wednesday comments:  I’m here in Corte Madera, California, visiting my good friend Linda.  I hope you have a good Wednesday wherever you happen to be spending it.

It’s cloudy here in Marin County with light showers, with a low temperature of 55 degrees in Linda’s backyard.

We have what’s called an Atmospheric River moving through northern California! It’s been off and on gusty with light to moderate rain falling all day. It’s dark, well not dark, although with the thick cloud cover overhead, I’ve got the light turned on in this room at mid-afternoon.

 

Hawaii’s Broad Brush Weather Overview:  Gradually diminishing trade winds will deliver just a few showers to windward areas of the smaller islands the next day or so, while windward Big Island will continue to receive passing showers.

Light and variable winds and mostly dry weather are expected statewide Thursday night into Sunday. A weak front may move over the islands from the northwest late this weekend, bringing little in the way of rainfall, with winds remaining on the lighter side.

Hawaii’s Weather Details:  The band of higher moisture that moved over the smaller islands during the evening and overnight hours is exiting the region early this morning, and is now confined to mainly the leeward Kauai waters, as drier air nudges in from the east. This drier airmass is resulting in a significant decrease in windward showers and low clouds over the smaller islands.

The exception, however, is the Big Island where latest satellite and radar imagery shows showers and low clouds embedded within the trade winds continuing to stream into windward locations. In the upper levels, a low aloft just south of the state is contributing to the continued shower activity for windward Big Island, but this feature will gradually weaken and drift off to the east over the next 24 hours. As this occurs, showers will gradually wane here too as the atmosphere becomes more stable.

Meanwhile, surface high pressure centered north of the islands is weakening as it moves south. Although locally breezy trade winds were observed last night, winds will continue on a downward trend for the next few days as this high continues to weaken, and several areas of low pressure pass north of the islands. The high is forecast to dissipate Friday, at which point a ridge will extend over the area from the east. Light and variable winds and mostly dry weather will prevail as the mid-level ridge persists. This pattern will continue Saturday.

Guidance continues to indicate that a weak or dissipating front will move over the islands from the northwest on Sunday, bringing a renewed chance of showers (though rainfall accumulations will be minimal). Models indicate high pressure will build north of the islands early next week, with Sunday’s post-frontal northwest winds veering to the northeast Monday and Tuesday. A mid-level ridge building over the area will support a mostly dry regime through the first half of next week.

Fire weather:  Minimum relative humidity values reached the critical 45% threshold, and will likely occur from late morning through the afternoon each day through Saturday. However, weakening winds will mitigate the potential for critical fire weather conditions.

Hawaii’s Marine Environment:  Surface high pressure settling in over the far north offshore waters will weaken regional trade winds to primarily gentle to locally moderate breezes by Thursday. The west-to-east orientated surface ridge axis of high pressure laying across the northern waters will result in generally light to gentle breezes across most coastal waters, with moderate trades over the Alenuihaha Channel and south of Big Island, the next several days. Light winds are favored ahead of the approach of a weak front nearing Kauai Sunday. Gentle breezes will veer northwest to northeast early next week behind this frontal passage.

No significant swells are expected the next few days with slowly subsiding trade wind waves; a more calm overall sea state going into the latter half of the week. Nearshore windward buoys are observing a near 5 foot trade wind swell, that will maintain above seasonal average rough east shore surf. This trade wind swell will decline Thursday and then further fade throughout the weekend.

A small northwest (320 degree) swell is due Thursday and will pass by Friday. A moderate size northwest (320 degree) swell developing from a pair of lows far northwest of the islands, is scheduled to travel through this weekend and peak Sunday. A smaller reinforcing northwest pulse (320 degree) is due Monday and Tuesday. Northeast (30 degree) swell originating from a very large, powerful hurricane force low churning off the U.S. Pacific Northwest coast, will begin arriving as a moderate size swell Friday and peak on Saturday. None of these swells are expected to produce advisory level surf.

Interesting:  Mount Fuji Bare Again After Fleeting Snow

As the calendar turned to November 2024, Japan’s iconic volcano and highest peak, Mount Fuji, still awaited the first snowfall of the season. When white did appear on its flanks on November 6, it was the latest in the year for the mountain’s first seasonal snowfall since records began 130 years ago. That beats the previous record of October 26, which occurred in both 1955 and 2016.

Ground and aerial photos from November 6 showed Mount Fuji with a fresh coating of snow on its peak. A local office of the Japan Meteorological Agency (JMA) officially confirmed the presence of snow on November 7, according to news reports; clouds had obstructed their view of the mountain the previous day.

By the time the OLI (Operational Land Imager) on the Landsat 8 satellite acquired this image on November 9, the new snow appears to have melted. For comparison, an image from October 30, 2023 acquired by the OLI-2 on Landsat 9, showed the mountain clad in white. That year, the first snow on Mount Fuji came on October 5, a more typical time for this annual milestone.
