Marine Winds – Here’s the latest (automatically updated) weather map showing high pressure systems to the northwest through northeast of the islands. Trade winds will be active through Tuesday.

Satellite and Radar Images: To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with this Infrared Satellite Image of the islands to see all the clouds around the state during the day and night. This next image is one that gives close images of the islands only during the daytime hours, and is referred to as a Close-up visible image. This next image shows a larger view of the Pacific…giving perspective to the wider ranging cloud patterns in the Pacific Ocean. Finally, here’s a Looping IR satellite image, making viewable the clouds around the islands 24 hours a day. To help you keep track of where any showers may be around the islands, here’s the latest animated radar image

Hawaii’s Mountains – Here’s a link to the live webcam on the summit of near 14,000 foot Mauna Kea on the Big Island of Hawaii. The tallest peak on the island of Maui is the Haleakala Crater, which is near 10,000 feet in elevation. These two webcams are available during the daylight hours here in the islands…and when there’s a big moon rising just after sunset for an hour or two! Plus, during the nights and early mornings you will be able to see stars, and the sunrise too…depending upon weather conditions.

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. Here’s a tracking map covering both the eastern and central Pacific Ocean. A satellite image, which shows the entire ocean area between Hawaii and the Mexican coast…can be found here.

Tropical storm Hilda east-southeast of Hawaii

The trade winds are expected to remain moderately strong through most of the upcoming week. The winds are strong enough to warrant small craft wind advisories across the island chain from Maui County down through the Big Island waters.

The windward sides will see off and on showers, although nothing heavy is expected. The leeward sides will be generally dry through this period, with fine weather expected. Later in the new week, as tropical storm Hilda moves by to the south of the state around Thursday…we may see some tropical moisture arriving for a few days then.

Tropical storm Hilda remains active to the east-southeast of the Hawaiian Islands Sunday night.  The hurricane models show this tropical storm staying several hundred miles south of the Hawaiian Islands. Here’s the latest National Hurricane Center tracking map. Here’s an IR satellite image, of Hilda…in relation to the Hawaiian Islands. There’s currently one other area that is also trying to spawn in the eastern Pacific between Hilda and the Mexican coast.

It’s Sunday evening here in Kula, Maui, as I begin writing this last part of today’s narrative update.  I had a very nice visit with my friend from Maui/Marin, joined by my two neighbors. The four of us had rousing conversation, with good food too. My friend left for her home in Haiku, while my neighbors and I decided to go up into the Haleakala Crater this afternoon. Wow, what a great hike, part of which was into the Crater using the switchback trail. The weather couldn’t have been more perfect, and we ended up getting home just at dark. I just can’t understand why I’m not hiking around that Crater every weekend! I bought a pass that lasts the rest of my life, and is good for entrance into any national park across the country…free. ~~~ I’m tired, and need to take a load off, jumping into bed, doing some reading, and falling fast asleep. I hope you have a great Sunday night! I’ll be back early Monday morning with your next new narrative. Aloha for now…Glenn.

Interesting: The U.S. Geological Survey released a study that showed mercury contamination in every fish sampled in 291 streams across the country. The work was part of the National Water-Quality Assessment Program (NAWQA) which provides an understanding of water-quality conditions such as whether conditions are getting better or worse over time and how natural features and human activities affect those conditions.

Regional and national assessments are possible because of a consistent study design and uniform methods of data collection and analysis. About a quarter of the fish were found to contain mercury at levels exceeding the criterion for the protection of people who consume average amounts of fish, established by the U.S. Environmental Protection Agency.

More than two-thirds of the fish exceeded the U.S. EPA level of concern for fish-eating mammals. "This study shows just how widespread mercury pollution has become in our air, watersheds, and many of our fish in freshwater streams," said Secretary of the Interior Ken Salazar. "This science sends a clear message that our country must continue to confront pollution, restore our nation’s waterways, and protect the public from potential health dangers."

Some of the highest levels of mercury in fish were found in the tea-colored or "blackwater" streams in North and South Carolina, Georgia, Florida and Louisiana — areas associated with relatively undeveloped forested watersheds containing abundant wetlands compared to the rest of the country. High levels of mercury in fish also were found in relatively undeveloped watersheds in the Northeast and the Upper Midwest.

Elevated levels are noted in areas of the Western United States affected by mining. Mercury, a neurotoxin, is one of the most serious contaminants threatening our nation’s waters. The main source of mercury to natural waters is mercury that is emitted to the atmosphere and deposited onto watersheds by precipitation.

However, atmospheric mercury alone does not explain contamination in fish in our nation’s streams. Naturally occurring watershed features, like wetlands and forests, can enhance the conversion of mercury to the toxic form, methylmercury. Methylmercury is readily taken up by aquatic organisms, resulting in contamination in fish.

An unexpected finding was that the production of methylmercury in channel sediment within the streams themselves appears to be relatively unimportant for controlling methylmercury in stream water. Stream water provides methylmercury to the base of the food chain, and it is the amount of methylmercury in the water that is the primary driver of how much mercury that accumulates in top predator fish.

In general, concentrations in fish increased with increasing concentrations of methylmercury in water. Once in the food web, methylmercury biomagnifies at a fairly consistent rate from algae to invertebrates to fish—even among diverse stream ecosystems. In the ecosystems studied, foodweb characteristics have less impact on the amount of mercury in fish than do methylmercury levels in water.

Interesting2: Kenya has been losing 100 lions a year for the past seven years, leaving the country with just 2000 of its famous big cats, says the Kenya Wildlife Service (KWS) — which concludes the country could have no wild lions at all in 20 years. Conservationists have blamed habitat destruction, disease and conflict with humans for the population collapse.

But Laurence Frank, a wildlife biologist at the University of California, Berkeley, thinks the KWS estimate is optimistic. "Lions are disappearing so fast from Kenya, as well as the rest of Africa, that I think they will disappear [from Kenya] in less than 10 years if action is not taken very quickly," says Frank, who runs several lion conservation projects in the country.

The IUCN suggests that large lion populations of 50 to 100 prides are necessary to conserve genetic diversity and avoid inbreeding. Frank says that the decline of the big cats is due to the inexorable growth in human population and consequent conflict with people over livestock, rather than disease.

Interesting3: Amidst waves and wildlife in the world’s oceans, billions of pounds of polystyrene, water bottles, fishing wire and other plastic products float in endless circles. This bobbing pollution is more than just an eyesore or a choking hazard for birds. According to a new study, plastic in the oceans can decompose in as little as a year, leaching chemical compounds into the water that may harm the health of animals and possibly even people.

"Most people in the world believe that this plastic is indestructible for a very long time," said Katsuhiko Saido, a chemist at Nihon University in Chiba, Japan. He spoke this week at a meeting of the American Chemical Society in Washington, D.C. "We are now concerned that plastic pollution is caused by invisible materials," Saido said through an interpreter. "This will have a great effect on marine life."

Interesting4: Mexico is suffering from its driest year in 68 years, killing crops and cattle in the countryside and forcing the government to slow the flow of water to the crowded capital. Below-average rainfall since last year has left about 80 of Mexico’s 175 largest reservoirs less than half full, said Felipe Arreguin, a senior official at the Conagua commission, which manages the country’s water supply.

"We have zones where the reservoirs are totally full but others that don’t have even a drop of water," he said in an interview late on Tuesday. More than 1,000 cattle have been lost due to lack of rainfall, and up to 20 million tons of crops managed by 3.5 million small farmers are at risk of being lost, agriculture groups say.
