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

It’s mostly clear here in Maui County early this morning, with a very chilly low temperature of 46 degrees at my place, with the relative humidity 58 percent.

Someone nearby has been lighting fireworks early this morning, before 6am…it’s still dark!

3pm, I played Pickleball this morning in Haiku, which as always was very fun. It’s partly cloudy in general, although there is a band of low clouds arriving along the windward sides now…which should bring a few showers.

Hawaii’s Broad Brush Weather Overview: Trade winds will become breezy tonight and Friday, as a band of moisture brings an increase in rainfall to mainly windward areas. Trade winds and shower activity will diminish on Saturday. An area of low pressure will develop northwest of the islands on Sunday then drift southward, causing winds to shift out of the southeast and bringing cloudy conditions, with increasing chances of showers and thunderstorms. Strong and gusty easterly winds are expected gradually reduce shower chances on Monday. Drier locally breezy trade winds are possible by Tuesday.

Hawaii’s Weather Details: Increasing trade winds will push a band of enhanced moisture across the islands tonight and Friday. For much of the day, the narrow band has been focused on Kauai, where more than a quarter of an inch of rainfall has fallen over windward slopes, and the feature has been starting to move onto Oahu and Maui County. A strong surface high centered 1400 miles north of the state, is producing breezy trade winds along and north of the moisture band.

The high will drift southeastward, pushing showers over windward areas from Kauai to Maui tonight and eventually to Big Island on Friday, where the band will stall and slowly dissipate. Breezy trade winds along and north of the band will periodically carry some showers over leeward areas, but a ridge aloft will maintain stable conditions that will keep rainfall totals modest.

Model guidance begins to diverge on Saturday, but overall, expect easterly trade winds to ease and rainfall to diminish as high clouds increase. The official forecast leans toward the ECMWF model, which is hinting at moisture hanging up on windward Big Island and keeping shower chances higher there.

Uncertainty in the details remains high later in the weekend, but probability of unsettled weather with locally heavy showers is increasing, especially over the western end of the island chain. Guidance continues to show an upper level low developing several hundred miles north of Kauai Saturday night and drifting west of Kauai late Sunday. The current forecast is based on the ECMWF and UKMET model solutions of a weak surface low or trough developing under the upper low, instead of the GFS, which appears to deepen the feature excessively and produce a strong surface low.

Under the favored ECMWF and UKMET solutions, winds will shift out of the southeast Saturday night and focus showers over windward and southeast slopes as high clouds thicken. The low at the surface and aloft is expected to pass to the west of the state Sunday and Sunday night, and broad convergence on its eastern flank will produce higher shower chances Sunday and Sunday night, especially over Kauai and Oahu. Thunderstorms have been introduced around Kauai and on the Big Island interior for the latest forecast.

Longer range guidance leans toward decreased rainfall chances and the development of strong and gusty east to southeast winds as the low drifts away to the west on Monday. Drier locally breezy trade winds are possible by Tuesday.

Hawaii’s Marine Environment: Moderate to locally strong easterly trade winds will continue through Friday, as high pressure builds north of the islands. Model trends indicate winds weakening and veering from the east to southeast direction this weekend, as an area of low pressure develops northwest of the state. The latest forecast guidance shows breezy to strong easterly trade winds building swiftly into Hawaiian Waters from Sunday into early next week.

A medium-period, north-northwest (340-350 degree) swell continues to lower and shift from a more northerly (350-360 degree) direction. Another moderate, medium-period, north-northeast (360-020 degree) swell will build into Hawaiian waters by early Friday morning, producing moderate surges into north facing harbors, as well as boosting surf heights along north facing shores to near advisory levels.

The latest north swell model guidance may be running 2 to 3 feet too low as compared to the long upstream generating fetch area. In any case, the swell heights 2 feet above model guidance for this next long duration Friday through Monday north-northeast swell that will peak from late Friday into Saturday, then diminish into Monday. The next long period, small northwest (310-320 degree) swell will build into Hawaiian waters by next Tuesday and then slowly decrease through the end of next week.

Choppy east shore surf will continue into Friday, before decreasing this weekend, as wind speeds begin to weaken shift out of the east-southeasterly direction. Stronger easterly trade winds starting on Sunday will build rough surf along east facing shores into early next week. Surf along south facing shores will remain tiny to small through the forecast period.

Peak astronomical monthly tides may produce minor coastal flooding through early next week, and may be enhanced along north facing shores later this week due to the next north swell. A Coastal Flood Statement has been issued to highlight this flooding potential through Friday night.

A building north-northeast swell over the next several days will also produce moderate surges for north facing harbors, especially for Kahului and Hilo.

Interesting:  Fine Particles in Pollution are Associated with Early Signs of Autoimmune Disease

A new study has linked air pollution exposure and immune-system changes that often precede the onset of autoimmune diseases.

McGill University researchers analyzing Ontario data found that fine particles in air pollution are associated with higher levels of a biomarker linked with autoimmune diseases, such as systemic lupus.

“These results point us in a new direction for understanding how air pollution might trigger immune system changes that are associated with autoimmune disease,” said Dr. Sasha Bernatsky, a James McGill Professor of Medicine and member of the McGill Centre for Climate Change and Health, the Division of Rheumatology and the Centre for Outcome Research and Evaluation. “We know some genetic factors play a role in autoimmune disease, but they don’t tell the whole story.”
