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.

Glenn’s Tuesday comments:  I’m at home here in upper Kula, Maui, Hawaii

540am, it’s totally clear here at my place, with the low temperature 53 degrees, relative humidity is 78%…with calm conditions

243pm, it’s partly cloudy here on Maui for the most part, along with quite a bit of haze in the air.

5pm, still partly cloudy along with the haze.


Hawaii’s Weather Highlights
…as of Tuesday evening:
Hurricane Nolo will slowly pass to the west of the state over the next couple of days, bringing increasing showers across Kauai and Oahu. Breezy southeast winds will continue through Wednesday, then gradually weaken and become trade winds by the weekend.

Weather Narrative…as of Tuesday evening: Hurricane Nolo is around 300+ miles west of Lihue tracking north at 8 mph. Nolo is expected to briefly stall west of the state tonight, then begin to move away to the west-northwest. Breezy southeast winds will continue across the state into Wednesday, as Nolo remains close to the area. While Nolo will not make direct impacts to the state, rain bands along the eastern periphery will move in the southeast flow, and bring showers across Kauai and Oahu through Thursday. Expecting to see 3 to 6 inches of additional rain on Kauai and Niihau, and up to 4 inches on Oahu. A Flood Watch is not expected as these rainfall amounts will be spread out over several days, and showers should be moving along quickly. However, southeast flow will direct showers across the populated areas of both islands.

The rest of the state will be under a hybrid east-southeast flow pattern, where the Big Island will partially block Maui County resulting in localized nighttime land breezes that will clear skies out, and daytime sea breezes that will bring interior cloud cover. Precipitation across Maui County and Big Island will be minimal. East-southeasterly winds will continue, but gradually weaken, through the second half of the week as Nolo tracks away. Winds will back to moderate trades by the weekend.

On Monday and Tuesday, a weak early season cold front will push across the islands, and stall near the Big Island through the remainder of the week. Winds will taper off behind this front, as a second cold front approaches much slower. Lingering clouds and showers near the Big Island and light winds state-wide next week will result in a daytime land and sea breeze weather pattern.

Fire Weather:  Wind speeds for most areas will decrease over the next 24 hours. However, wind speeds for Kauai County will increase into the breezy range with higher gusts through Wednesday, as Hurricane Nolo passes roughly 300 miles to the west of the islands. Nolo`s passage will boost humidity levels, decreasing critical fire concerns. Subsidence inversion heights near Maui and the Big Island today will remain between the 5,500 and 6,500 feet elevation level.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Looping Surface Precipitation…through the next 8-days / Vog Map

 

Marine Conditions…as of Tuesday evening: Moderate to fresh SE winds prevails over area waters. Strong to near-gale SE flow will develop tonight into Wednesday around Kauai, due to Hurricane Nolo`s close proximity. The Small Craft Advisory remains in effect for these waters. Moderate trades return early next week.

The moderate, medium period SW swell originating from Nolo has eased slightly, with the latest observations coming in below the High Surf Advisory (HSA). The HSA has therefore been allowed to expire. Surf along E shores has declined in response to emerging SE flow. Surf will remain small until moderate trades return early next week, providing a modest boost. Multiple rounds of tiny swell originating out of the northwest quadrant will reach north and select west facing exposures next week, as the storm track in the vicinity of the Aleutian Islands becomes increasingly active.

Interesting: 
Sheep Grazing May Pose Greater Threat to Scotland’s Wild Pollinators Than Honey Bees

The research, published in the British Ecological Society’s Journal of Applied Ecology, has found that grazing in spring can remove much of the nectar emerging bumblebees need, while commercial honey bee hives introduced during the summer heather flowering period have a much smaller impact.

Commercial beekeepers across Europe regularly move hives onto heather moorland during the summer flowering of ling heather. This has raised concerns about competition between honey bees and wild pollinators, including bumblebees, butterflies, moths and beetles.

To find out the best way to protect them, researchers from Bristol’s School of Biological Sciences surveyed plant and pollinator communities at 20 moorland sites across Scotland over a full flowering season (May to September), comparing plots with and without introduced honey bee apiaries, and comparing land that was actively grazed and burned using ‘muirburn’ practices against land left to regenerate naturally.
