Hawaii’s MountainsHere’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. This webcam is 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.

Small Craft Advisory…windiest coasts and channels Maui County and the Big Island

 

~~~ Hawaii Weather Narrative ~~~

 

Broad Brush Overview: Gusty trade winds will continue into Saturday, with clouds and showers remaining focused over windward and mountain areas. Some brief showers will reach leeward sections of the smaller islands. The winds will decline through the weekend, becoming light and variable…with afternoon sea breezes Sunday. Kona winds ahead of a cold front will bring increased moisture with much wetter conditions for the first half of next week.

Details: As this rather vigourous cold front approaches Kauai Monday, the models are showing moisture pooling over Oahu, Maui County, and the Big Island. This tropical moisture as it impacts island terrain, will likely produce heavy rain, isolated thunderstorms, and the potential of flash flooding for the eastern islands through mid-week.

Kona winds (south through southwest) will increase Monday as well, with some potential for gusty winds accelerating down the terrain into windward areas of Kauai and Oahu. Current model runs are showing southwest winds just below the damaging wind threshold, although this forecast could change with time.

The front will push over Kauai Monday night bringing moderate rains with it. The front will then slowly move eastward, likely passing east of Oahu Tuesday, and then east of the Big Island Wednesday night. North winds behind the front will bring cool and dry conditions to Kauai Tuesday, and possibly Oahu Wednesday…while moist and humid conditions will remain in place over Maui County and the Big Island.

Looking further Ahead: Model guidance diverges for the second half of the week, ranging between a stabilizing upper ridge over the state, in contrast to a destabilizing upper low just north of the islands. The current long range forecast maintains moderate trade winds with windward showers…time will tell. The main thing here seems to be that we’re leaving our placid summer weather behind, and pushing deeper into our autumn season.

Marine environment details: The current strong to gale force trade winds will be diminishing steadily over the weekend. Light and variable winds are expected by Sunday, as the high to the north weakens and moves east, and a low develops in the same area. This low will send a cold front towards the islands early next week, and the forecast now expects the front to move across Kauai and Oahu late Monday into Tuesday, with associated changeable winds and weather.

With high pressure currently fueling strong trade winds, a Gale Warning remains in effect today for the Pailolo and Alenuihaha Channels, while a Small Craft Advisory (SCA) remains posted elsewhere. The diminishing winds will likely allow the Gale Warning to expire tonight, and the SCA will likely be lowered for all areas by early Saturday. Although wind waves will be lowering, building north-northwest and south swells Sunday and Monday are expected to keep combined seas elevated…although below the SCA criteria.

A moderate north-northwest swell has been building and will peak later today and then lower Saturday. A larger northwest swell is expected Sunday and Monday, likely resulting in advisory level surf along north and possibly west facing shores. This swell will begin to diminish Tuesday, although another larger northwest swell is expected late Tuesday into Wednesday.

Additionally, advisory level surf along south facing shores is possible Sunday and Monday, generated by a distant low in the South Pacific. A small west swell is possible next week, generated by large and slow-moving Typhoon Lan in the Western Pacific.

Regreening the Planet Could Account for One-Third of Climate Mitigation
Planting trees, restoring peatlands, and better land management could provide 37 percent of the greenhouse gas mitigation needed between now and 2030 to keep global warming to 2 degrees Celsius, according to a new study published in the Proceedings for the National Academy of Sciences.

The activities, known as natural climate solutions, could prevent up to 11.3 billion tons of carbon dioxide from reaching the atmosphere every year, the study reported. That would be the same as if nations stopped burning oil completely, The Nature Conservancy, which helped lead the study, said.

To achieve these greenhouse gas reductions, nations would need to engage in reforestation efforts, peatland and coastal wetland restoration, and the conversion of former agricultural land to forests, as well as protect existing forests and wetlands from future development.

These actions “also offer water filtration, flood buffering, soil health, biodiversity, and enhanced climate resilience,” the scientists wrote. “Regreening the planet through conservation, restoration, and improved land management is a necessary step for our transition to a carbon neutral global economy and a stable climate.”
