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

It’s mostly cloudy with light rain here in Marin County, with a low temperature of 48.5 degrees in Linda’s backyard.

It’s been cloudy all day so far, with not the slightest bit of sunshine. There’s been off an on light showers falling, with the temperature hovering around 56 degrees.

 

Hawaii’s Broad Brush Weather Overview:  Stable and somewhat dry conditions will persist as light northerly winds will shift to a more typical northeasterly direction Tuesday and Wednesday. Expect modest rainfall over windward slopes, while daytime sea breezes produce afternoon clouds and minimal showers over leeward terrain. Trade winds will strengthen Thursday and Friday, then decline Sunday and next Monday.

Hawaii’s Weather Details:  Stable and somewhat dry conditions are expected during the next couple of days. A weak northerly flow over the islands is being driven by a departing area of low pressure centered northeast of Hawaii, and developing surface high pressure to the northwest.

While this flow is not as dry as the weekend airmass, only a few light showers are expected over most windward and north facing slopes, with higher chances for some rainfall on windward Big Island and east Maui tonight.

The weak flow will be overpowered by daytime sea breezes, and while some afternoon clouds can be expected over leeward terrain, the only places with a significant chance for any rainfall will be the leeward slopes of the Big Island and Haleakala on Maui.

As a weak surface ridge builds north of the state late Tuesday and Wednesday, winds will gradually swing around from a more typical northeasterly direction, but little change is due in the rather dry rainfall pattern. Also, as a ridge aloft builds overhead from the west, high clouds will move away from the Big Island.

Trade winds are expected to slowly build Thursday, and may become locally breezy Friday, as the surface ridge to the north strengthens. Very stable conditions will prevail on Thursday as a ridge aloft passes overhead then, giving way to a shallow upper-level trough that will bring a period of thickening high clouds again Friday and Saturday. With moisture in the trade wind flow below seasonal average, limited windward rainfall and rather dry conditions leeward are favored.

Model guidance suggests the surface ridge will be displaced southward toward the islands Sunday and Monday, hinting at weakening trade winds.

Fire weather:  Significant rainfall remains highly unlikely through at least the weekend. During the next couple of days, relative humidity is expected to be above the critical fire weather threshold, and winds will remain weak. As a result, critical fire weather conditions are not anticipated through Wednesday. At this point, the winds on Thursday through Saturday look to fall short of critical levels, but conditions should remain rather dry, leading to some fire weather concerns.

Hawaii’s Marine Environment:  Light to moderate northerly winds will persist through Tuesday, then transition to moderate to fresh northeast to east trades by mid-week, as high pressure builds north of the area in the wake of a diminishing front. Expect localized wind accelerations into the moderate to fresh category near and along some east and west facing coasts through the late morning and afternoon periods, while the background northerly flow persists. Winds may ease by the weekend with a potential front passing to the north.

Surf along exposed north and west-facing shores will hold around the advisory levels, then begin to gradually lower later tonight through mid-week, as a northwest (310 degrees) swell fades. A fresh northwest swell will arrive, peak late Tuesday into Tuesday night, and then gradually subside through Thursday. Toward the end of the week, a larger northwest (300-320 degrees) swell is expected due to a storm-force low developing around 1500 NM northwest of the islands this week. If conditions develop as forecast, surf heights could reach warning levels late Friday into early Saturday, before easing gradually over the weekend.

Surf along east-facing shores will remain up through the first half of the week, as a small north-northeast (020 degrees) swell lingers. By late week, a northeast swell generated by strong winds north of a broad area of low- pressure developing about 1000 NM northeast of the islands, may arrive Friday and peak over the weekend.

Surf along south-facing shores will remain near seasonal averages this week, driven by a mix of  southeast and south-southwest swells. Early next week, an out-of-season south-southwest swell is possible, originating from a broad gale passing southeast of New Zealand. This active trend may persist through the first week of December, as a similar system passing near New Zealand is forecast to follow later this week.

Interesting: From Zero to 80 Per Cent in Just 15 Minutes

Electric Vehicles will now be able to go from zero battery power to an 80 per cent charge thanks to Researchers at the University of Waterloo who made a breakthrough in lithium-ion battery design to enable this extremely fast charging. 15 minutes is much faster than the current industry standard of nearly an hour, even at fast-charging stations.

Batteries made using this new design are also able to withstand more charges – up to 800 cycles, a feat not possible with current EV batteries.

“We need to make EVs more affordable and accessible, not just for the wealthy,” said Yverick Rangom a professor in the Department of Chemical Engineering. “If we can make batteries smaller, charge faster, and last longer, we reduce the overall cost of the vehicle. That makes EVs a viable option for more people, including those who don’t have home charging stations or who live in apartments. It would also increase the value of second-hand EVs, making electric transportation more accessible.”
