~~~ Hawaii Weather Commentary ~~~
Our trade winds will continue to be strong and gusty into mid-week, reaching 30-40+ mph in gusts locally at times. Here's a weather chart showing a broad, east-west area of moderately strong high pressure to the north of Hawaii. At the same time, we see many deep storm and gale low pressure system systems far to the north and northwest…one of which has a cold front draping down into the sub-tropics to our northwest. Our trade wind weather pattern will prevail, with the winds continuing to be stronger than normal into Thursday. The outlook through the rest of this week, calls for the trade winds to finally begin to ease up slowly Friday into the weekend.
Satellite imagery shows low clouds along our windward sides in places…with clear to partly cloudy conditions along our leeward sides for the most part. At the same time, we see those brighter and whiter higher clouds that are over the ocean well to the northeast through southeast. As the gusty trades remain blustery over the next few days, they will bring us periodic windward biased showers. The next area of showery clouds appears just upstream of the islands this evening…which will bring increasing showers to our windward sides tonight into Wednesday morning. 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 week, although the winds will finally mellow-out starting Friday. 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 just parts of the eastern islands…with high surf advisories active over east facing shores as well.
As for rainfall, there will be off and on showers along the windward sides. Low pressure aloft will prompt active windward shower activity into the weekend, 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, perhaps increasing showers then along our windward sides. ~~~ I'll be back with more updates this evening, along with a new weather narrative early Wednesday morning. I hope you have a great Tuesday night wherever you happen to be spending it! Aloha for now…Glenn.

Interesting: The North Atlantic right whale, along with many other whale species, is set to benefit from work by scientists to reduce the noise levels caused along shipping routes. One of the rarest of the large whales, the North Atlantic right whale is thought to have a population of just 500 individuals, and it is believed that excessive noise along shipping routes is likely to negatively affect this threatened species.
The din from commercial ships makes it extremely difficult for the marine mammals to communicate with one another, which in turn means that their ability to locate food and mates, and therefore their ability to sustain a viable population, is greatly diminished.
Research indicates that noise levels in the New England region of North America have doubled each decade over the past 30 years. To counteract this problem, scientists have persuaded shipping companies to alter their routes in and around the Boston area, which plays host to several species of whale, many of which are suffering as a result of increased noise levels.
An iPad application has been developed which enables sea captains to visualize the locations of whales across the USA's entire East Coast, and to know when to slow their ships down. Results indicate that this change in operations has already helped to significantly lower the amount of noise pollution in the area.
To a whale, it is thought that the sound of a passing container ship could be like a 'thunderous, unchanging drone'. "It's as if you are talking at a cocktail party and all of a sudden it is hard to hear because there is all this background noise," said Dr Mark Baumgartner of the Woods Hole Oceanographic Institution.
"A couple of words get dropped, you don't get the meaning of everything that is said to you. That is what it is like for a lot of whales in the ocean right now." In addition to the problems caused by the disruption in whale communication, ships are also known to physically collide with whales on occasion.
While such incidents are limited to just one or two a year, this presents a serious problem for a species of which only 500 or so individuals remain. Worryingly, research also indicates that mothers with calves get hit more frequently.
"Our scientists found shattered bone and large hematomas which are indicative of a ship strike," said Dr Dave Wiley of the National Oceanic and Atmospheric Administration. It is hoped that the new iPad app will go some way to limiting the frequency of such accidents.
