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. Here's the Haleakala Crater webcam on Maui.
Tropical Cyclone activity in the eastern and central Pacific – Here’s the latest weather information coming out of the National Hurricane Center, covering the eastern north Pacific. You can find the latest tropical cyclone information for the central north Pacific (where Hawaii is located) by clicking on this link to the Central Pacific Hurricane Center. A satellite image, which shows the entire ocean area between Hawaii and the Mexican coast…can be found here. The 2012 hurricane season is over in the eastern and central Pacific…resuming on May 15th and June 1st 2013.

~~~ Hawaii Weather Commentary ~~~
Our trade winds will continue to be strong to very strong and gusty, reaching 40-60 mph in gusts locally at times. Here's a weather chart showing a large and strong, near 1037 millibar high pressure system to the north of Hawaii…with a new high pressure cell moving into place to our northwest by Tuesday. At the same time, we see deep storm and gale low pressure systems far to the northwest…one of which has a cold front draping down into the tropics to our far west. Our trade wind weather pattern will prevail, with the winds continuing to be stronger than normal. The outlook for this week calls for blustery trade wind weather to remain active.
Satellite imagery shows low clouds along our windward sides in places, with passing showers at times…with clear to partly cloudy conditions along our leeward sides for the most part. At the same time, we see those brighter and whiter high cirrus clouds that are over the ocean to the east. These high icy cirrus were clipping the Big Island, although are slowly drifting away to the east at the time of this writing. As the gusty trades remain blustery this week, they will bring us windward biased showers at times. The leeward sides will see some clouds too, with a few showers flying over into those areas here and there.
The current trade weather pattern will extend through the rest of this work week, with strong and gusty trade winds prevailing. We continue to have small craft wind advisories stretching across the entire state now, with gale warnings up around Maui and the Big Island. Wind advisories are also in force across all of the island chain now…with high surf advisories active over many north, west, and east facing shores as well. The summits on the Big Island are cold, with snow falling at times. The Aloha state has rather rugged environmental conditions on tap for the time being…at least in quite a few places!
As for rainfall, there will be off and on showers along the windward sides…mostly on! Low pressure aloft will prompt active windward shower activity, enhancing shower intensity at times. As the trade winds remain strong and gusty, some of these showers will drift over into the leeward sides here and there. The weather models are pointing out the chance of low pressure edging over the state during the upcoming weekend, prompting more wet weather then. ~~~ I'll be back with more updates on this windy, and locally showery episode this evening. I hope you've had a great President's Day holiday wherever you happen to have spent it! Aloha for now…Glenn.

Interesting: Efforts to reduce lead pollution have paid off in many ways, yet the problem persists and will probably continue to affect the health of people and animals well into the future, according to experts speaking at the annual meeting of the American Association for the Advancement of Science (AAAS) in Boston. "Things have substantially improved with the virtual elimination of leaded gasoline, restrictions on lead paint, and other efforts to limit releases of industrial lead into the environment.
But the historic legacy of lead pollution persists, and new inputs of industrial lead are adding to it," said A. Russell Flegal, professor of environmental toxicology at the University of California, Santa Cruz. Flegal will present a history of industrial lead contamination and explain why the problem won't go away in a AAAS symposium on Saturday, February 16.
The good news, he said, is that atmospheric lead concentrations in the United States have fallen by 89 percent in the past three decades, and average blood lead levels in U.S. children have shown a corresponding decline, from 15 micrograms per deciliter (ug/dL) in 1976 to 1.3 ug/dL in 2008.
The bad news is that blood lead levels are still about 100 times higher than the natural background level, and there is no known threshold for lead toxicity. In other words, even tiny amounts of lead in the body can be harmful.
Lead pollution is a 5,000-year-old problem, Flegal said, citing elevated lead levels in Chinese lake sediments deposited during the Bronze Age. Recent records from U.S. lake sediments show decreases in lead pollution since the phasing out of leaded gasoline began in the 1970s.
But industrial activities around the globe continue to release more lead into the environment. Major sources of lead emissions include the burning of coal, especially in developing countries such as China and India.
Lead from these sources spreads around the globe, so that environmental lead contamination can be detected even in "pristine" environments such as the Arctic and the Swiss Alps, Flegal said.
