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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Thursday comments:  I’m at my friend Linda’s here in Corte Madera, Marin County, CA on a working vacation.

402am HST, it’s mostly clear with thin high clouds here in Corte Madera, CA, the low temperature was 42.5 degrees…with calm winds

1222pm HST, lots of rain, some heavy, remained focused over Maui County. Here in Marin County it was like Indian Summer this morning, although the clouds have thickened up this afternoon.

431pm HST, it appears that most of the heaviest showers have migrated down over parts of the Big Island this afternoon. Here in Marin it’s dark of course, and the temperature has dropped to 53 degrees.

 

Hawaii’s Weather Highlights…as of Thursday evening: The flooding threat will remain active, primarily across the windward areas of the Maui and the Big Island. Conditions will generally be improving tonight through Friday, but some localized downpours will continue for windward areas through Friday. For Oahu and Kauai, fair trade wind weather will persist over the next few days. Breezy to locally strong trades will fill in Sunday afternoon and persist through early next week.

Weather Narrative…as of Thursday evening: Satellite and radar imagery shows isolated thunderstorms over windward Big Island. While abundant low-level moisture remains across the state with dew points in the 70’s, drier mid-level air has moved in over the western half of the state. With the abundant low level moisture still lingering over the western half of the state, any passing showers will be capable of producing brief downpours through Friday.

Over the eastern half of the state, the drier mid-level air should be moving in tonight. Overall, with drier air moving in, and land breezes developing over the Big Island, the current heavy showers and isolated thunderstorms should taper off. So for now, the plan is to keep the Flood Watch going through 6pm with no extension anticipated, as long as the current bands of heavy rain begin to taper off over the next hour or so.

While the threat of flash flooding should be generally decreasing overnight, some localized heavy rain is still expected over select windward areas of East Maui and windward Big Island tonight through Friday. Mid-level ridging building overhead should keep the threat of any thunderstorms low, and should bring stable conditions by Friday afternoon.

For Halloween, weather conditions should generally be fair across the state, with gentle to moderate trade winds. Some low level moisture may still linger over the eastern half of the state, which will likely produce some scattered showers over windward and mauka areas. Otherwise, fair weather should prevail for rest of the state.

A strong high building behind a weak front passing near the state, should produce strong, northerly relatively cool and breezy conditions on Monday. A breezy to locally strong trade wind pattern is expected early next week, with scattered showers focused over windward and mauka areas.

Fire Weather: Due to the recent rain and light wind, fire weather concerns will remain low through Saturday. A front is expected to arrive early next week. Breezy to locally strong north northeast winds and drier conditions are expected in the wake of this boundary passage late Sunday or early Monday. Thus, fire weather concerns will be on the rise through next week.

Marine Conditions…as of Thursday evening: Weak trough over the central waters will slowly move south and dissipate Friday. This has continued to support showers and isolated thunderstorms over the eastern waters and looks to continue, before conditions slowly improve. Ridging to the north will gradually drive moderate to fresh easterly winds over most waters Friday through the weekend. As trade winds increase, a Small Craft Advisory for the windier waters and channels around Maui County and the Big Island is likely late this weekend into early next week.

The current northwest swell will gradually decline through the evening before a small short period north-northeast swell will fill in Friday and maintain small surf. A larger, long- period northwest swell will arrive late Saturday and will likely push surf above the High Surf Advisory threshold Sunday into Monday. The swell will shift more northerly and may briefly build further on Monday before dropping Tuesday. At the peak of the swell coinciding with the 360 degree direction, a Marine Weather Statement may need to be issued to due the potential for harbor surges at Kahului and Hilo harbor.

Surf along south facing shores will slowly rise through this evening, peak Friday just below High Surf Advisory levels, and gradually decline through the weekend. By early next week, surf looks to remain tiny to small through the forecast period.

Surf along most east-facing shores will remain small and choppy through today but will rise Friday with the wrapping north to north- northeast swell energy, producing periods of moderate surf. Exposed shorelines to the north swell may be impacted along the east side Sunday night into Monday with the potential for surf to reach High Surf Advisory level surf possible.

Interesting:  Schools Increasingly Affected by Poor Air Quality as Wildfire Smoke Becomes More Common

American children are increasingly exposed to air pollution as wildfire smoke becomes more common, and some schools and childcare centers struggle to keep indoor breathing conditions clean, a new national study shows.

The researchers note that components of wildfire smoke, including PM2.5, which is fine particulate matter with a diameter of 2.5 micrometers or smaller, are known health hazards, especially for adolescents and younger children.

For the study, published in Environmental Research, scientists looked at air quality data from across the United States from 2006 through 2023 and found some alarming trends, said co-author Molly Kile of Oregon State University.

“The average number of annual smoke days at public schools rose from 6.8 to 54.4 between the beginning and end of the study period,” said Kile, an environmental epidemiologist in the OSU College of Health. “Childcare centers experienced an increase from 9.4 to 112.2 days. Our children are collectively experiencing billions of days of smoky air each year.”
