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 Thursday comments:  I’m at home here in upper Kula, Maui, Hawaii

It’s partly to mostly cloudy, with calm winds at my place, and with a low temperature of 59 degrees and the relative humidity is 85%

1220pm, I played pickleball down in Makawao, where it was cloudy and lightly showering when I left. As I drove back home it showered off and on all the way up…and it’s still lightly showering as these words.

330pm, it’s partly to mostly cloudy, and with the winds now east-southeast or southeast, so that we’re seeing vog coming up from the vents on the Big Island…in the air here in Maui County.

440pm, it’s cloudy, and we are having a light shower here at my place in upper Kula.

Hawaii’s Broad Brush Weather Overview…as of Thursday evening: A weak trough and its associated moisture plume over the western end of the state, will shift northwest through Friday, bringing a slight increase in shower activity as it passes through. Otherwise, a lighter wind flow will allow for a sea/land breeze pattern to persist into the weekend, with showers developing over leeward and interior areas each afternoon, followed by clearing at night. Then trade winds will gradually strengthen through next week, shifting the shower focus to windward and mountain areas.

Weather Details for the Hawaiian Islands…as of Thursday evening: Radar and visible satellite imagery show a slightly veered east- southeast wind flow steering clouds and isolated showers parallel to the island chain. The bulk of the clouds and showers are remaining just east of the state, and along a weakly convergent boundary associated with the weak surface trough near Kauai, but clouds and a few showers have also managed to develop over leeward and interior areas of each island with the afternoon sea breezes.

The surface trough will weaken further and gradually shift northwest of the state through Friday, with moderate east-southeast winds filling in behind it through Saturday. Winds will briefly take on an east-northeasterly tilt on Sunday as a front/trough approaches from the northwest. With wind speeds gradually strengthening, a mix of windward and mountain showers, with isolated afternoon sea breeze leeward and interior showers can be expected through the weekend. In addition muggy conditions will prevail through much of the weekend as well.

Heading into next week, the subtropical high to the far northeast will regain control, and easterly trades will build to moderate to breezy levels through mid-week. This will usher in slightly lower dew points, and combined with the breezier trades, some relief from the mugginess. Model guidance suggests that an upper level low will pinch off of the longwave trough to the far north, and approach the state from the northeast mid to late-week, possibly providing some enhancement to windward and mountain showers, as batches of moisture move through.

Marine Environmental Conditions…as of Thursday evening: Light to moderate trades will hold for the next few days as a weak surface ridge remains to the north and a broad surface trough continues to move west over the island chain the next few days. The weak trough is currently located between Oahu and Kauai waters and is producing some scattered showers over the coastal and offshore waters. Scattered showers will generally decrease over the coastal waters by Friday. Trades may increase slightly over the weekend as the trough dissipates, with more pronounced strengthening early next week as the ridge strengthens to the north.

A moderate, long period south swell is peaking at advisory levels this afternoon, thus a High Surf Advisory remains in effect for all south facing shores through early Friday morning. This swell should drop below advisory levels by Friday as the swell gradually fades late tonight into the weekend. A series of smaller south- southwest swells will fill in Sunday into the first half of next week and will maintain surf near seasonal averages through next week.

Tiny surf will prevail on north and east shores through most of the coming week. A slight increase in east shore surf is expected around next Tuesday or Wednesday as trade winds build across the region.

Offshore East Coast of the United States (Remnants of Arthur):

Showers and thunderstorms associated with a trough of low pressure (the remnants of Arthur) are located over the southeastern United States. The system is expected to emerge offshore the east coast of the United States on Friday. Environmental conditions then appear to be marginally conducive for some subtropical or tropical development on Friday or Saturday as the system moves northeastward at 15 to 20 mph across the Western Atlantic Ocean.

Regardless of development, heavy rainfall with the potential for widespread and life-threatening flash flooding is likely across portions of the Southeast United States during the next day or two.

Interesting: From Speed to Stability: How Ageing Changes the Way We Walk

Reasons why our walking becomes slower and more tiring with age have been uncovered by new Australian research — with findings showing the body increasingly sacrifices efficiency to stay upright.

The study, led by Flinders University and the University of Canberra, reveals that as we age, the body adopts a “safety-first” walking style that prioritizes stability at the cost of speed and energy efficiency, which helps explain why older adults tire more easily and face a higher risk of falls.

Analyzing movement data from 107 healthy adults aged 26 to 86, researchers identified subtle but important changes in how the ankle and surrounding muscles control each step.

Lead author and expert in sport and exercise technology, Dr Cody Lindsay, says the ankle plays a critical role in both balance and forward motion.
