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.

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!

Hawaii’s Broad Brush Weather Overview: Moderate trade winds will focus showers over windward and mountain areas through today. A band of enhanced moisture (the remnants of an old dissipated cold front) will move across the state tonight into Friday, bringing an increase in rainfall and stronger trade winds. Drier trades return Saturday. Winds will turn southeast Sunday, followed by a potential increase in showers Sunday through Monday night. After that, a return to drier trades is likely.

Hawaii’s Weather Details: An upper level ridge will slowly move over the islands through Friday night, allowing a surface high to spread southward over us and to our east. This will allow a fresh push of trade winds to bring a moisture boundary (remnants of an old cold front) into the area today through tonight. This will enhance showers windward and mountain, and could lead to a few moderate showers. The atmosphere is relatively stable Friday into Saturday, so heavy rain and flooding are not considered serious concerns with this system.

Late Saturday into Sunday, a strong upper level low will move southeast toward the state. This will likely result in the formation of a surface low several hundred miles to the northwest, but models are very inconsistent (even more than usual, especially at this time range) with their solutions on strength and location. Therefore, there is a tremendous amount of uncertainty in the forecast for Sunday through Monday.

The potential exists for quite a rainy period, with upper levels cold enough for thunderstorms. If this solution verifies, surface winds would come out of the southeast, and heavy rain is likely. The latest data suggests this is the most likely solution, but uncertainty is high enough that there is still a chance we could end up experiencing a more typical transition back to east or northeast trades, with showers continuing mainly windward and mountains…stay tuned.

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.”
