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 Tuesday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good Tuesday wherever you happen to be spending it.

It’s clear, with a cool low temperature of 49 degrees according to my outside temperature sensor.

Interestingly, the high temperature was a very warm 88 degrees at the Kahului AP, after a cool 59 degree low! That’s a full 29 degree range…which is unusual to say the least.

515pm, Christmas Eve officially started at 5pm, at least in my book, so, here’s wishing you all a very Merry Christmas Eve!

837pm, the afternoon clouds have cleared quickly, and as a result the temperature has dropped quickly to 55.4 degrees here at my Kula weather tower…after a high temperature of 72.5 degrees.

 

Hawaii’s Broad Brush Weather Overview:  Winds will weaken veer east-southeasterly Wednesday and become light and variable Thursday into Friday, prompting sea breezes and land breezes. A shallow cold front and upper level disturbance will move into the islands this weekend, and may bring a period of more active weather.

Hawaii’s Weather Details:  A surface high centered northeast of Hawaii, has an associated ridge extending southwest, passing within 300 miles north of Kauai. A weakening front moving away from the islands lies to the east-northeast, with an approaching front to the northwest.

Winds will gradually taper off through Thursday and veer east-southeasterly as the ridge moves closer to the islands, in response to the approaching front from the northwest. Rainfall amounts will be minimal through Friday with highest chances across windward Big Island. Winds will become light and variable Thursday and Friday, and likely invoke daytime sea breezes and nighttime land breezes.

The shallow front is forecast to arrive on Kauai Saturday, and stall near the Big Island Sunday night into early next week. An upper low or trough will form near or east of the Big Island. Still too early to tell if there will be impacts to the eastern end of the state, given the differences in the long range models. Breezy trade winds will fill in behind the front through the weekend.

Fire weather:  No critical fire weather conditions are expected for the next seven days. Mostly dry weather are forecast across the state with limited shower activity as the dry spell continues through Friday. Shower trends increase starting Friday night with trade wind showers.

Hawaii’s Marine Environment:  Fresh to strong easterly trades continue over the eastern half of the state. Winds have veered slightly out of the southeast over the western half of the state and eased to moderate to locally fresh. The Small Craft Advisory (SCA) has been scaled back to windward Oahu waters and waters east of Oahu, due to the combination of strong winds and lingering high seas. Winds and seas are expected to drop below SCA thresholds as winds continue to gradually ease and shift out of the southeasterly. Winds are expected to become light and variable for the western half of the state Wednesday night into Friday. East to southeast winds will persist over the eastern half of the state and become gentle to moderate Thursday into Friday.

The current northwest swell (310-330) continues to trend down at the offshore and near shore buoys. The High Surf Advisory (HSA) for north and west facing shores has been dropped, as the swell continues to trend down at the local buoys. The next large northwest swell (310 degrees) is expected to fill in late Wednesday night, peak Thursday before gradually trending down Friday into the weekend. This second swell is excepted to produce warning-level surf along north and west facing shores, albeit smaller than the event this past weekend. This large swell will also elevate seas to above SCA thresholds as the swell fills in Wednesday night. Surf along east facing shores will briefly become rough and choppy as trade wind swell has picked up. A downward trend is expected during the second half of the week as winds weaken locally and upstream.

Interesting:  Study Finds Fluoride in Water Does Not Affect Brain Development

A University of Queensland study has found no link between exposure to water fluoridation as a young child and negative cognitive development.

Professor Loc Do from UQ’s School of Dentistry said the IQ scores of 357 people who had participated in the 2012–2014 National Child Oral Health Study were assessed by registered psychologists to see if their exposure to fluoride as a young child impacted their brain development.

With the participants now aged 16 to 26 years old, we found those who’d consistently been drinking fluoridated water had an IQ score 1.07 points higher on average than those with no exposure,” Professor Do said.
