Hawaiian Islands weather details & Aloha paragraphs

A well established trade wind weather pattern will continue, with rather strong and gusty winds dominating for the time being. Large high pressure centers far to the north and northeast of Hawaii, are the source of our blustery trade wind flow now. Small craft wind advisory flags remain up over just about all coastal areas, and all the major channels in Hawaii. As we move into the weekend, we should see the wind speeds mellowing out a little, although the trade winds will stay us right on into next week, remaining in the moderately strong category.
 
The blustery trade winds will continue to carry a few showery clouds to the windward sides of the islands. An upper level trough of low pressure is moving away to the east Hawaii Tuesday evening. This will keep our atmosphere a bit unstable for a little long, although losing its influence soon. As the trade winds are quite strong, a few showers may get carried over into the leeward sections on the smaller islands. 

It’s Tuesday evening as I begin updating this last paragraph of today’s narrative. As you can see, if you have a few seconds to look at this satellite imagery, there are lots high level cirrus clouds riding in on the jet stream level winds now. This kept island skies rather cloudy Tuesday, dimming and filtering our famous Hawaiian sunshine effectively. We may see a temporary break in the high overcast, although there appears to be more cirrus coming our way further to the west of Kauai. ~~~  The upper level trough of low pressure, which caused the recent thunderstorm activity over Maui and the Big Island, is slipping away to the east. This should put us back into a fairly normal trade wind weather pattern, at least in terms of rainfall along the windward coasts and slopes. The winds won’t be normal however, taking on strong and gusty proportions over the next couple of days. ~~~ I’ll be back again very early Wednesday morning with your next new weather narrative from paradise. I hope everyone has a great Tuesday night until then! Aloha for now…Glenn.

Interesting2: Researchers say they have shown for the first time that humpback whale calves make sounds. The nonprofit Cetos Research Organization, which studied humpbacks off Maui and Kauai, say the grunts and squeals emitted by the young whales are messages for their mothers. Ann Zoidis, director of the research project, said the sounds may be expressions of curiosity or warnings of potential danger. The sounds are not as complex as the continuous, repetitive and highly structured phrases and themes of older males, the researchers found. The calves instead produced a limited number of sounds that were short and simple in structure, according to the study. The noises included repetitive grunts that increased in strength and were sometimes accompanied by bubble streams and seemed to function as an alarm call to the mother, the researchers found. They say the sounds were produced more frequently during calmer periods when the mother was resting or during slow travel. "This tells us that calves do in fact communicate, and it tells us they are communicating to their mothers,” Zoidis said.
