Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the Haleakala Crater 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.

Special Weather Statement in south Big Island…Although radar data has not detected any significant bursts of volcanic ash from Halemaumau Crater over the past several hours, additional bursts of ash remains possible at any time. Northeast trade winds have returned and will continue for the next few days. This low level trade winds will push ash toward the southwest, and any ash fallout will likely occur over the Kau District and Highway 11 southwest of the town of Volcano. This includes the communities of Pahala, Wood Valley, Naalehu and Ocean View.

With winds spreading ash in the same direction, repeated eruptions will lead to a heavier buildup of ash. In addition, any ash deposited over the last several days will likely be picked up by local winds, contributing to dusty conditions.

Avoid excessive exposure to ash which is an eye and respiratory irritant. Pele`s hair and other lightweight volcanic glass from high fountaining fissures are being transported downwind. Residents are urged to minimize exposure to these volcanic particles, which can cause skin and eye irritation similar to volcanic ash. Those with respiratory sensitivities should take extra precaution to minimize exposure.

Small Craft Advisory…All coastal and channel waters statewide 

Wind Advisory…Lanai, Kahoolawe, Maui Central Valley, Big Island north and east Kohala / 25-35 mph with gusts to 50+

 

~~~ Hawaii Weather Narrative ~~~

 

Broad Brush Overview: A steady trade wind flow will continue through Friday, as high pressure is well established far northeast of the state. Showers will focus over windward and mountain locations as usual. Periods of high and middle level clouds will prevail…as an upper low remains positioned to the west. Trades may weaken some by the weekend, as the ridge of high pressure to the north becomes less influential.

Details: Models show the surface trough, which caused a brief period of lighter trades recently, shifting westward. Trades will become stronger as high pressure rebuilds to the northeast. The sun dimming high and middle level clouds will prevail over the state. Low level moisture riding in on the trades, will bring showery conditions mostly over the windward sides…with an occasional shower spilling over into leeward areas on the smaller islands. 

Looking Ahead: A more stable and typical trade wind pattern is forecast to return through the second half of this week beginning Wednesday, as high pressure remains north and northeast of the state. Clouds and showers that do develop through this period will focus over windward locations. High level clouds however, may lead to cloudy conditions at times…as the upper low shifts eastward or back toward the state. These higher clouds are famous for bringing colorful sunrise and sunsets at times.

As we push into the weekend time frame, the models support a weakness developing within the ridge to our north, as a cold front passes by well north of the state. If this develops as expected, the trades may relax once again locally. This would simply mean that we could see a few showers breaking out during the afternoon hours, along the upcountry slopes. As far as tropical cyclone activity, the central Pacific hurricane season begins June 1st…although I don’t see anything on the horizon in that regard.

Marine Environmental Conditions: A weak surface trough just west of the islands will shift westward and further away from the area over the next few days as a strong area of high pressure builds to the north of the state. Trade winds will strengthen today, reaching breezy levels tonight through Wednesday night. Trades will ease a bit Thursday through the weekend, but moderate to breezy conditions should prevail. A Small Craft Advisory (SCA) remains in effect for the typically windy waters around Maui and the Big Island through Wednesday night. This SCA may need to be extended through the end of the work week. Additionally, as the trade winds peak tonight through Wednesday night, the SCA may need to be expanded to include some additional marine zones.

A new SSW swell will build today and reach above- average heights tonight through Thursday. After a trend downward Friday and Saturday, another above average south swell is expected to build on Sunday, possibly peaking close to advisory levels early next week. Surf along east facing shores will remain small through today, then rise to above average heights tonight into the upcoming weekend. Only small surf is expected along north facing shores.

Interesting: The Science of Sleep: A Brief Guide on How to Sleep Better Every Night – Sleep is one of the strangest things we do each day. The average adult will spend 36 percent of his or her life asleep. For one-third of our time on earth, we transition from the vibrant, thoughtful, active organisms we are during the day and power down into a quiet state of hibernation.

But what is sleep, exactly? Why is it so important and so restorative for our bodies and minds? How does it impact our lives when we are awake!

The Purpose of Sleep

Sleep serves multiple purposes that are essential to your brain and body.

The first purpose of sleep is restoration. Every day, your brain accumulates metabolic waste as it goes about its normal neural activities. While this is completely normal, too much accumulation of these waste products has been linked to neurological disorders such as Alzheimer’s disease.

Alright, so how do we get rid of metabolic waste? Recent research has suggested that sleep plays a crucial role in cleaning out the brain each night. While these toxins can be flushed out during waking hours, researchers have found that clearance during sleep is as much as two-fold faster than during waking hours.

The way this process occurs is fairly remarkable:

During sleep, brain cells actually shrink by 60 percent, allowing the brain’s waste-removal system—called the glymphatic system—to essentially “take out the trash” more easily. The result? Your brain is restored during sleep, and you wake up refreshed and with a clear mind.

The second purpose of sleep is memory consolidation. Sleep is crucial for memory consolidation, which is the process that maintains and strengthens your long-term memories. Insufficient or fragmented sleep can hamper your ability to form both concrete memories (facts and figures) and emotional memories.

Finally, sleep is paramount for metabolic health. Studies have shown that when you sleep 5.5 hours per night instead of 8.5 hours per night, a lower proportion of the energy you burn comes from fat, while more comes from carbohydrate and protein. This can predispose you to fat gain and muscle loss. Additionally, insufficient sleep or abnormal sleep cycles can lead to insulin insensitivity and metabolic syndrome, increasing your risk of diabetes and heart disease.
