Hawaii’s MountainsHere’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 – if it’s working.

~~~ Hawaii Weather Narrative ~~~

Moderately strong trade winds, although with stronger gusts through Friday, lighter Saturday…then stronger again Sunday into early next week. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the Pacific Ocean. We find strong high pressure system far to the northeast of the state, with the tail-end of an associated ridge extending southwest…not far north of Hawaii. At the same time we see gale and storm low pressure systems far to the north and northwest, with associated cold fronts draping down, located far north and northwest of our islands. ~~~ Our local winds will continue to come in from the trade wind direction through the rest of this work week. Our Christmas holiday will have moderately strong trade winds blowing, although with stronger gusts…otherwise great weather will prevail.

We’ll find a few showers, mostly along the windward sides during the night and early morning hours…lots of sunshine during the days on the leeward beaches.
Satellite imagery shows a minor amount of clouds around the islands…with one small area of high clouds far to the east-southeast. Here’s the looping radar image, showing that there are some showers being carried towards the windward sides of the islands from Oahu down through Maui County to the Big Island…at the time of this writing. We’ll find fairly typical trade wind showers drifting across our area through at least Thursday. The leeward sides will have minimal shower activity…with lots of warm sunshine beaming down during the days!

We’ll be experiencing a typical, early winter trade wind weather pattern through Friday…with a weak cold front arriving later Saturday into Sunday. The models continue showing another cold front approaching the state later Friday into the weekend. This front will move down into our chain of islands, although it’s still a question just how far it will make it before stalling. This rather weak front will bring its associated showery weather…although nothing heavy is expected. I’ll be back Christmas morning with your next new weather narrative, I hope you have a great Tuesday night wherever you’re spending it. I hope you all got your Christmas shopping taken care of in time, and wake up in good spirits and health on this special morning! Aloha for now…Glenn.

  Tsunami threat to Sumatra continues – A great offshore earthquake, like the one that killed hundreds of thousands when it struck off Indonesia’s Sumatra coast in December 2004, would seem to offer a small measure of solace to survivors: The offshore tectonic fault that caused the temblor should require many centuries to recharge. Now, it appears such optimism is unwarranted. Three speakers here at the fall meeting of the American Geophysical Union earlier this month warned that the Indian Ocean coast of northern Sumatra could suffer another tsunami disaster in as few as 60 years.

That sobering news came in three talks by paleoseismologists—researchers who literally dig up records of past earthquakes and tsunamis-associated with Nanyang Technological University’s Earth Observatory of Singapore. Charles Rubin, Kerry Sieh, Jessica Pilarczyk, and their colleagues had been reading the millennia-long histories of past tsunamis in three kinds of geologic records and determining the age of each tsunami recorded there using radioactive carbon-14 dating.

The most novel record was found in a cave located 200 meters from the present-day coastline. Only the far-reaching inland surge of a tsunami can carry sand into this cave, where it can then be deposited layer by layer, tsunami by tsunami. Conveniently enough for the researchers, tsunami deposits in this cave are demarcated by dark layers of guano deposited between tsunamis by the cave’s resident bats. Other records were retrieved from tsunami deposits in coastal wetlands and exposed in eroding sea cliffs.

Taken together, the new records paint a disconcerting picture of highly erratic tsunami recurrence.
