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. This webcam is 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.

A low pressure system southwest of Kauai will keep off and on showers around…with a very long cold front to the north and northwest of the islands

The unusual low pressure system, spinning in a counter-clockwise, is dropping down into the area southwest of the islands, bringing localized showers in its wake

This low pressure system is moving away from the islands…although is pulling lots of clouds and rain over parts of the islands from the east and southeast

Small Craft Advisory…Maalaea Bay and Pailolo Channel


~~~ Hawaii Weather Narrative ~~~

 

Winds will be generally from the southeast and locally gusty. Here’s the latest weather map, showing a rather strong high pressure system located far northeast. At the same time, we have a low pressure system to the west, moving away towards the southwest. As the low moves away from the state into Monday, our winds will come in from the southeast and then east. Looking ahead, we should see the return of trade winds later Monday into Tuesday…which are expected to become locally stronger and gusty well into the new work week.

A Kona low pressure system just west of Hawaii…will spin off into the area southwest into Monday. We’ll see showers falling locally, although not in a widespread fashion by any means. The most active showers will occur into Monday morning…with the chance of localized flooding issues. Following this episode of unsettled weather, we should find windward showers returning, brought in on the trade winds beginning late Monday into Tuesday onward. We might actually see a more typical trade wind weather pattern, with a drying trend returning by the middle of the week. The outlook for next weekend shows that a trade wind weather pattern will hold sway.

Marine environment details: This rather dynamic wind, wave and weather episode will prevail over the waters surrounding the islands through early Monday, as a Kona low pressure system, west-northwest of Kauai moves steadily toward the west-southwest, and weakens. Surf generated by the circulation around the Kona low will continue to diminish today. However, a new northwest swell generated by a more distant low, is forecast to spread down the island chain this morning. These two swells are expected to produce surf near the High Surf Advisory criteria along exposed north and west facing shores of most of the smaller islands this morning.

Winds across the islands will gradually shift from south to southeast today and tonight as the low moves away from Kauai. A Small Craft Advisory (SCA) remains in effect for the waters surrounding Kauai and the Oahu windward waters. In addition, strengthening southeast winds, just east of the state will also likely boost combined seas to near the SCA criteria. As a result, the Big Island and Maui County windward waters have been added to the SCA. Note that the southeasterly flow will oppose the north-northwest swell, so expect steepening of the waves and rough conditions where the strongest southeast winds occur. Seas are forecast to eventually subside below the SCA threshold by Monday over all waters. However, when fresh to strong trade winds return, and another north-northwest swell arrives Monday night and Tuesday, a SCA will likely be issued for some waters around Maui and the Big Island. The SCA will need to be extended to additional waters by mid-week.

The new north-northwest swell arriving Monday night could potentially produce advisory level surf along exposed north and west facing shores of the smaller islands Tuesday and Wednesday. In addition, the stronger trades may result in a High Surf Advisory along east facing shores later in the new work week.

Interesting: ‘Chemtrails’ not real, say atmospheric science experts – Well-understood physical and chemical processes can easily explain the alleged evidence of a secret, large-scale atmospheric spraying program, commonly referred to as “chemtrails” or “covert geoengineering,” concludes a new study from Carnegie Science, University of California Irvine, and the nonprofit organization Near Zero.

Some groups and individuals erroneously believe that the long-lasting condensation trails, or contrails, left behind aircraft are evidence of a secret large-scale spraying program. They call these imagined features “chemtrails.” Adherents of this conspiracy theory sometimes attribute this alleged spraying to the government and sometimes to industry.

The authors of this study, including Carnegie’s Ken Caldeira, conducted a survey of the world’s leading atmospheric scientists, who categorically rejected the existence of a secret spraying program. The team’s findings, published by Environmental Research Letters, are based on a survey of two groups of experts: atmospheric chemists who specialize in condensation trails and geochemists working on atmospheric deposition of dust and pollution.

The survey results show that 76 of the 77 participating scientists said they had not encountered evidence of a secret spraying program, and agree that the alleged evidence cited by the individuals who believe that atmospheric spraying is occurring could be explained through other factors, such as typical airplane contrail formation and poor data sampling.

The research team undertook their study in response to the large number of people who claim to believe in a secret spraying program. In a 2011 international survey, nearly 17 percent of respondents said they believed the existence of a secret large-scale atmospheric spraying program to be true or partly true. And in recent years a number of websites have arisen claiming to show evidence of widespread secret chemical spraying, which they say is linked to negative impacts on human health and the environment.

“We wanted to establish a scientific record on the topic of secret atmospheric spraying programs for the benefit of those in the public who haven’t made up their minds,” said Steven Davis of UC Irvine. “The experts we surveyed resoundingly rejected contrail photographs and test results as evidence of a large-scale atmospheric conspiracy.”

The research team says they do not hope to sway those already convinced that there is a secret spraying program — as these individuals usually only reject counter-evidence as further proof of their theories — but rather to establish a source of objective science that can inform public discourse.

“Despite the persistence of erroneous theories about atmospheric chemical spraying programs, until now there were no peer-reviewed academic studies showing that what some people think are ‘chemtrails’ are just ordinary contrails, which are becoming more abundant as air travel expands. Also, it is possible that climate change is causing contrails to persist for longer periods than they used to.” Caldeira said. “I felt it was important to definitively show what real experts in contrails and aerosols think. We might not convince die-hard believers that their beloved secret spraying program is just a paranoid fantasy, but hopefully their friends will accept the facts.”
