Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. 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.
Our trade winds will continue blowing, moderately
strong…increasing some over the next few days
We’re involved in a normal trade wind weather
pattern…albeit a bit windier than usual at times
An area of tropical moisture will bring showers and
sultry weather our way later Thursday into Friday, first
on the Big Island and Maui County, on the other islands
into Saturday…some possible heavy showers
Small Craft Wind Advisory…windiest coasts and
channels around Maui County and the Big Island
~~~ Hawaii Weather Narrative ~~~
Our trade winds will remain active, blowing in the moderately strong range for the most part…locally stronger at times locally. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profile of the central Pacific…focused on the Hawaiian Islands. We have a moderately strong high pressure system located to the northeast of the state, with a ridge of high pressure running southwest from its center. At the same time, we have several low pressure system that are about to move by to the south of the state over the next several days. The forecast calls for the trade winds to remain active, increasing a notch or two for several days..as these tropical disturbances migrate from east to west.
Satellite imagery shows very few low level clouds over the area…with streaks of higher cirrus clouds over some parts of the state. Looking at this larger looping satellite image, it also shows considerable thunderstorm activity over the ocean to the southwest, south, and southeast of the state..which is sending high clouds northward into our area locally. There’s also patches of low clouds to the east, although very few at the time of this writing, being carried our way on the trade wind flow. Here’s the looping radar, showing just a few showers falling locally along the windward sides, which will remain rather limited for several more days.
A fairly normal trade wind weather pattern will prevail through mid-week…followed by increased showers into the weekend. In that regard, the models continue showing an increase in showers associated with what is now former tropical cyclone Geneieve…moving by to the south of the state over the next couple of days. As this area of tropical moisture gets closer, our weather will turn sultry and more shower prone Thursday into the weekend. As this remnant low pressure system moves by well south of the state, it will trigger gusty trade winds at times. Then, a bit later in the week, the northern fringe of its moisture may stretch northwards enough, to bring showers our way. I’ll be back again early Tuesday morning, I hope you have a great Monday night wherever you happen to be spending it! Aloha for now…Glenn.
World-wide tropical cyclone activity:
Atlantic Ocean: There are no active tropical cyclones
Satellite data indicate that an area of low pressure located about 1000 miles west-southwest of the Cape Verde Islands is becoming better defined. The associated shower and thunderstorm activity continues to gradually organize, and a tropical depression could form during the next day or so while the system moves westward or west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours…high…70 percent
* Formation chance through 5 days…high…80 percent
Here’s a satellite image of this area of disturbed weather – and what the hurricane models are showing for this area being referred to as Invest 93L
Caribbean Sea: There are no active tropical cyclones
Gulf of Mexico: There are no active tropical cyclones

North Eastern Pacific: Post-Tropical Cyclone 08E (Hernan) is dissipating, here’s the NHC graphical track map…along with a satellite image – Final Advisory
1.) A large area of cloudiness and showers extending several hundred miles off the southwestern coast of Mexico is associated with a tropical wave. Environmental conditions appear conducive for gradual development of this system later this week or this weekend while it moves westward to west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 5 days…medium…30 percent
Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.
Central Pacific Ocean: There are no active tropical cyclones
1.) The weak remnant low of former tropical depression Genevieve was located about 660 miles southeast of Hilo, Hawaii. The surrounding environment may permit this system to redevelop slightly as it continues to move west near 10 mph during the next couple of days.
* Formation chance through 48 hours, medium…30 percent
2.) A weak center of low pressure area was located about 700 miles south southwest of Oahu. The surrounding environment may permit this system to develop slightly as it continues to move west near 10 mph during the next couple of days.
* Formation chance through 48 hours, low, 20 percent
3.) A weak center of low pressure area was located about 1500 miles southwest of Oahu. The surrounding environment may permit this system to develop slightly as it continues to move west near 10 mph during the next couple of days.
* Formation chance through 48 hours, low…10 percent
4.) An area of low pressure located about 1200 miles east-southeast of Hilo, Hawaii moved westward at about 10 mph. The associated shower activity diminished, environmental conditions in its proximity were unfavorable, and a larger area of disturbed weather associated with remnants of Genevieve was located nearby, so this system is not expected to develop.
* Formation chance through 48 hours, low…near 0 percent

Interesting: Industrial lead pollution beat explorers to the South Pole by 22 years – Norwegian explorer Roald Amundsen became the first man to reach the South Pole in December of 1911. More than 100 years later, an international team of scientists led by Joe McConnell of Nevada’s Desert Research Institute (DRI) have proven that air pollution from industrial activities arrived long before.
Using data from 16 ice cores collected from widely spaced locations around the Antarctic continent, including the South Pole, McConnell’s team created the most accurate and precise reconstruction to date of lead pollution over the Earth’s southernmost continent. The new record, described in an article published today in the online edition of the Nature journal Scientific Reports, spans a 410-year period from 1600 to 2010 A.D.
“Our new record shows the dramatic impact of industrial activities such as smelting, mining, and fossil fuel burning on even the most remote parts of the world,” said McConnell, the study’s lead author, research professor and director of DRI’s ultra-trace ice core analytical laboratory, located on the institute’s campus in Reno, Nev.
“It is very clear that industrial lead contamination was pervasive throughout Antarctica by the late 19th century, more than two decades before the first explorers made it to the South Pole,” he added. “The idea that Amundsen and Scott were traveling over snow that clearly was contaminated by lead from smelting and mining in Australia, and that lead pollution at that time was nearly as high as any time ever since, is surprising to say the least.”
All measurements of lead and other chemicals used in this study were made using DRI’s unique continuous ice core analytical system. Low background atmospheric concentrations, together with well-known and often distinct isotopic characteristics of industrial sources make lead an ideal tracer of industrial pollution.
“Lead is a toxic heavy metal with strong potential to harm ecosystems,” said co-author Paul Vallelonga of the University of Copenhagen. “While concentrations measured in Antarctic ice cores are very low, the records show that atmospheric concentrations and deposition rates increased approximately six-fold in the late 1880’s, coincident with the start of mining at Broken Hill in southern Australia and smelting at nearby Port Pirie.”
The similar timing and magnitude of changes in lead deposition across Antarctica, as well as the characteristic isotopic signature of Broken Hill lead found throughout the continent, suggest that this single emission source in southern Australia was responsible for the introduction of lead pollution into Antarctica at the end of the 19th century and remains a significant source today, the authors report.
