This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times.

~~~ Hawaii Weather Narrative ~~~



Generally light breezes through the weekend…a tad stronger locally on Saturday Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean. We find high pressure systems east-northeast, northeast, and west of Hawaii.
In addition, there’s numerous low pressure systems far to the northeast through northwest of Hawaii. The recent firm trade wind flow will be weakening soon, giving way to lighter winds, and daytime sea breezes this weekend. A cold front moves towards or through the state Sunday night into Monday…with chilly northerly winds in its wake for several days, until they turn more northeast mid-week. These trade winds will give way to more light winds later next week, as another cold front moves into the state next weekend.

Here’s a wind profile…of the offshore waters around the islands – with a closer view

Here’s the Hawaiian Islands Sulfate Aerosol…animated graphic showing vog forecast

Scattered showers here and there at times, mostly windward Saturday…then upcountry areas Sunday afternoon. The lighter winds this weekend will allow afternoon clouds to develop along the leeward slopes, with a few showers possible. At the same time, we might still see a few showers crossing the windward sides here and there at times too. The latest models continue showing a cold front arriving Sunday night into Monday, bringing a new batch of showers to our area for a day or two then. The northerly winds behind this weak front, will bring cool conditions, and potentially a few more showers our way into the middle of next week. Looking even further ahead, yet another cold front will arrive next weekend, ushering in some more showers.

Special Surf Statement: The recent warning and advisory level high surf continues to pound our north and west facing beaches today…although will be dropping in size into Saturday. Meanwhile, a new advisory level northwest swell will fill in Saturday night, peak on Sunday, then lower gradually Sunday night into next Monday. Yet another large northwest swell will gradually fill in late Monday and Monday night with its expected peak next Tuesday.

Here in Maui County
It’s mostly clear early this Friday morning….with a bit of haze beginning to show up. Here in upcountry Kula we have an air temperature of 47.4F degrees well before sunrise. The temperature at near the same time was 63 degrees down in Kahului under clear skies, 66 out in Hana also with clear skies, and 45 degrees up at the summit of the Haleakala Crater. Meanwhile, Kahoolawe was 66 degrees, 62 at Lanai City, with 64 at the Molokai airport.

Mid-afternoon, under partly cloudy skies….and thick volcanic haze.

Early evening, under partly cloudy skies…and incredibly thick volcanic haze! I’m hoping that when the gentle trade winds return Saturday, that they might help clear this vog away. It might very well come back again Sunday, as the winds turn lighter again, and may veer to the southeast and south ahead of the next weak cold front Monday.

Friday Evening FilmThere are all kinds of new films that have shown up in our local Maui theaters. One in particular jumped right out at me, which is called Triple Nine, starring Casey Affleck, Kate Winslet, Woody Harrelson, Teresa Palmer, Anthony Mackie, Chiwetel Ejiofor and Gal Gadot...among others. The synopsis: In Triple Nine, a crew of dirty cops is blackmailed by the Russian mob to execute a virtually impossible heist, and the only way to pull it off is to manufacture a 999, police code for “officer down.” Their plan is turned upside down when the unsuspecting rookie they set up to die foils the attack, triggering a breakneck action-packed finale tangled with double-crosses, greed and revenge.

My friend Jeff and I took this movie in, and we pretty much knew exactly what we were getting into. It didn’t take long before we were actively involved in shootouts and bloodshed on the streets of Atlanta. It was like a war zone, with so many tough guys doing their things, so heavy…so so heavy! It was a little slow in places, although one soon forgets those brief moments, when the action kicks in again, which it did over and over believe me. This was a very dark crime drama, with barely the light of day sneaking in around the edges occasionally. The cast was so good, with many top notch actors involved, it had to be pretty darn good, and it was. Jeff mentioned on the drive back up the mountain, that he felt rather exhausted from sitting through all that nasty business, and I felt the same way. Did I like it, absolutely, although its difficult to give a grade to a film with so much killing involved! This was a rough and tumble film, no two ways about it…here’s the trailer.

I’ll be back with many more updates on all of the above and below, I hope you have a great Friday night wherever you’re spending it! Aloha for now…Glenn

New Heat Wave Formula Can Help Public Health Agencies Prepare for Extreme Temperatures
– Extreme heat can pose several health risks, such as dehydration, hyperthermia and even death, especially during sustained periods of high temperatures. However, a uniform definition of a heat wave doesn’t exist. As a result, public health agencies may be unsure of when to activate heat alerts, cooling centers and other protective measures. A University of Missouri School of Medicine researcher has developed a uniform definition of a heat wave that may help public health agencies prepare for extreme temperatures.

“According to climate models, temperatures in Florida are predicted to increase over the next 100 years, yet there can be confusion regarding what constitutes a heat wave,” said Emily Leary, PhD, assistant research professor in the Biostatistics and Research Design Unit at the MU School of Medicine. “As temperatures rise, it’s important to have a uniform definition that best allows public health agencies to prepare for heat waves, whether that means issuing more frequent heat advisories or opening more cooling stations. Using Florida as our model — a state known for its heat — we set out to develop a data-driven definition of a heat wave that can be used for public health preparation. This formula can be adapted and applied to other parts of the country as well.”

The U.S. National Weather Service currently initiates heat alert procedures when the heat index — the perceived temperature in relation to humidity — is expected to exceed 105 to 110 degrees Fahrenheit, depending on the area. However, the United Nations’ Intergovernmental Panel on Climate Change defines a heat wave as five or more consecutive days with maximum temperatures approximately 9 degrees Fahrenheit higher than normal. These definitions become confusing when different sources use differing methods to define climatology norms, Leary said.

Additionally, the definitions may not be suited for certain regions, such as Florida, because the area may have consistently high temperatures and fewer true seasons, which do not account for extreme temperatures or resident acclimation. Previous research also has shown that using local or region-specific meteorological thresholds better reflect a temperature extreme for a certain area.

Leary’s definition, which is informed by previous research, factors in relative and absolute heat index thresholds for a given region and time. The temperature must exceed the 80 percent relative heat index threshold, meaning the heat index must be higher than 80 percent of the region’s temperatures for a given period. In addition, a region also should have at least three non-consecutive days with a heat index above an absolute regional heat index threshold, a predetermined temperature based on regional climates.

For example, in Pensacola, Florida, a heat index higher than 100.6 degrees Fahrenheit for three days means that the area has the potential to experience a heat wave. A heat index higher than 110 degrees Fahrenheit for three days would be considered a heat wave.

“This formula better explains when a heat wave is occurring because it accounts for missing weather data and better captures what extreme heat means for a region,” Leary said. “Because this formula uses National Weather Service regions, there also is an existing infrastructure to communicate alerts.”
