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. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.

The swath of thick clouds, oriented northeast to southwest…
is now moving away to our east

There’s hardly any more showery clouds over the islands…
with the high cirrus clouds now having cleared the state

Showers have diminished greatly…mostly dry everywhere

Cool winds from the north, then become easterly trade winds into the weekend.
Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find high pressure systems well to the northwest and northeast of the islands. At the same time, we have low pressure systems well to the north and northeast of the islands. The placement of these low and high pressure areas, along with the tail-ends of several cold fronts will keep gusty northerly breezes over us tonight
. As we get into the weekend…a more easterly trade wind air flow will finally move over the state. The outlook suggests that the upcoming trades will be short-lived, as one or two late winter cold fronts approach the state next week. As for winds, we’ll likely find them turning lighter, and coming in from variable directions…before trade winds increase again towards next weekend.

Clear to partly cloudy skies…good weather into the weekend. The thick plume of multi-layered clouds is now moved to the east of the Big Island, and continues to slowly shift further east. Much drier conditions will prevail, albeit on the cool side for the time being. The models suggest the return of more classic trade wind conditions this weekend, with just a few windward showers by Sunday. As noted above, those trades will likely slip away early next week, as more late season storms pass by to the north of the state, perhaps dragging a cold front or two across our area later in the week. By the way, for you folks who will be going to our north or west facing beaches into the weekend, be careful of the still large waves that will be breaking there. I’ll be back with more updates on all of the above, I hope you have a great Friday night wherever you’re spending it! Aloha for now…Glenn.

Here on Maui: The skies are clearing over Maui early this morning, with just a few showers falling here and there. My weather deck here in Kula this morning, well before sunrise, is still wet from some light showers that fell overnight. The low temperature was 51,7 degrees here at my Kula weather tower, while it was 64 degrees down at the Kahului airport, 63 at the Hana airport, and 37 degrees atop the Haleakala Crater at the same time. The warmest low temperature around the state was 69 degrees in Kailua-Kona on the Big Island…while the coolest was 63 at Poipu, on Kauai.

~~~ Hi it’s 335pm Friday afternoon, here in Kula, under sunny skies, a cool north wind…and an air temperature of 59 degrees. This is a chilly temperature for the middle of the afternoon, even in the winter months. It’s that type of day that’s chilly in the shade, and warm in the sun…although there’s definitely a wind chill factor going on.

~~~ Hi again, it’s now just 505pm, in the very early evening, and it’s almost totally sunny, with a cool 56.9 for a temperature. It’s breezy from the north direction, which is going to make for a cool night…more so it the winds decide to slow down some. / It’s now 945pm here in Kula, and the air temperature is a very chilly 45.5 degrees! At this rate, we may see the temperature plummeting into the upper 30’s by early Saturday morning…I’ll let you know. / It’s now 1020pm, and the temperature continues to slip down, now its 42.8. Just for comparison, down near sea level at the same time, at the Kahului airport, the temperature was way warmer…at 69 degrees!

Friday Evening Film: There really wasn’t to much that Jeff, Svetlana and I wanted to see in terms of exciting films, so we just picked one that looked like the best of what little there was that caught our eye. It’s called Focus, starring Will Smith, Margot Robbie, Gerald McRaney, Rodrigo Santoro, Stephanie Honore…among many others. The synopsis: A con artist (Will Smith) takes on an inexperienced apprentice in this crime comedy. I’ll let you know what we thought Saturday morning, although none of us have high h0pes. ~~~ We all more or less liked it, with Svetlana giving it a B+, Jeff a straight B, and I gave it a strong B grade. I went in with low expectations, and was pleasantly surprised at how entertaining it was in the end. There were the expected twists and turns…out of a film that promotes itself as a con job. It was fun to know you were about to be fooled once again, and yep, it happened again and again. The lead actress was exceptionally attractive, we all agreed, which helped carry the film in many places. Even the love affair between Will Smith, and this beautiful woman, slid time after time into a set of lies. Here’s a trailer in case you have a little interest.

Interesting: Princeton University geologists mapping the Earth’s mantle in 3DWhen a 7.9-magnitude earthquake struck central China’s Sichuan province in 2008, seismic waves rippled through the region, toppling apartment houses in the city of Chengdu and swaying office buildings 1,000 miles away in Shanghai.


Though destructive, earthquakes provide benefit in one respect: they help researchers learn about the structure of the Earth, which in turn could lead to more accurate predictions of damage from future quakes and volcanic activity. By eavesdropping on the seismic vibrations of quakes as they rumble through the Earth, researchers can detect the existence of structures such as mineral deposits, subterranean lakes, and upwellings of magma. Thanks to a growing earthquake detection network and superfast computers, geoscientists are now able to explore the Earth’s interior, a region that has been more inaccessible than the deepest ocean or the farthest planet in our solar system.


Princeton geosciences professor Jeroen Tromp and his team have embarked on an ambitious project to use earthquakes to map the Earth’s entire mantle, the semisolid rock that stretches to a depth of 1,800 miles, about halfway down to the planet’s center and about 300 times deeper than humans have drilled. For the task, his team will use one of the world’s fastest supercomputers, Titan, which can perform more than 20 quadrillion calculations per second and is located at the Department of Energy’s Oak Ridge National Laboratory in Tennessee.


Computer simulations use the speed of seismic waves from earthquakes to reveal the existence of subterranean structures. In this view of the mantle below the Pacific Ocean, slower waves are shown in red and orange while faster waves are shown in green and blue. The faster waves are associated with subduction zones where one tectonic plate sinks underneath another plate.

“Seismology is changing at a fundamental level due to advances in computing power,” said Tromp, who earned his Ph.D. in geology from Princeton and is Princeton’s Blair Professor of Geology, professor of applied and computational mathematics, and associate director of the Princeton Institute for Computational Science and Engineering. “If someone had told me what seismology would look like 20 years from when I graduated from Princeton in 1992, I would have never believed it.”


For the project, Tromp will use seismic waves from roughly 3,000 quakes of magnitude 5.5 and greater, recorded at thousands of seismographic stations worldwide and distributed via the National Science Foundation’s Incorporated Research Institutions for Seismology. These stations make recordings, or seismograms, that detail the movement produced by seismic waves, which typically travel at speeds of several miles per second and last several minutes.


“The ultimate goal is a 3-D map on a global scale,” said Tromp, who expects to have preliminary results at the end of this year. “We are specifically interested in the structure of mantle upwellings and plumes,” he said, “but much of it will be investigating the images for unusual features.”
