Tornado, hail, and torrential rains hammer Hawaii

A waterspout made landfall on the Hawaiian island of Oahu Friday morning on the east shore town, becoming a rare Hawaiian tornado as it moved through the towns of Lanikai and Kailua. The twister, rated an EF-0 with winds of 60 - 70 mph, tore holes in roofs and downed trees along a 1 1/2 mile long, 20-yard wide path of damage. No injuries were reported. The same storm also brought golf ball sized hail raining down for about 45 minutes on Oahu. The islands have seen intense rains over the past week, thanks to a 1040 mb blocking high pressure system near 40°N, to the NNW of the island that forced a companion cutoff low near 25°N 165°W to stay put, bringing a series of heavy storms to the islands. Rainfall amounts over the past week have exceeded three feet in some locations. The resulting flooding forced the governor on Wednesday to declare two islands, Oahu and Kauai, disaster areas. The latest forecasts for Kauai and Oahu call for sporadic rains to continue over the weekend, followed by a drying trend during the coming week.


Video 1. On March 5, 2012, flooding rains of 3" per hour caused this creek to overflow the Loop Road on Kauai and wash away a pickup truck that tried to cross. The occupants evacuated safely.

Here are some select rainfall amounts over the past week, from the National Weather Service:

Hawaii's tornado history
Tornadoes are rare in Hawaii. According to the Tornado History Project, only 39 tornadoes have hit the state since 1950, an average of one tornado every 1.5 years. The strongest tornadoes to hit the state occurred in 1982, when a series of three F-2 twisters struck Oahu in February and March. Those months are the most frequent months for tornadoes, with 44% of the total. No one has ever been killed in a Hawaiian tornado, but six people have been injured.

Quoting emguy:


Actually, Hurricane Charley was not a home grown system. His origins were of a true Cape Verde nature. He was a tropical wave that came off Africa and passed through the Carribean with little circumstance. Thunderstorms became much better organized while approaching the Leewards, but advisories did not begin until the wave passed through the islands. At the time of passage through the islands, it was noted by NHC that there was a sharp 4MB pressure drop and on further analysis, advisories were initialized.

Other notes about Charley would include his ability to find a favorable environment despite a very rapid forward motion through both the Carribean and the Gulf. Second, Charley was a storm that remained small in size, but more interestingly, remained small and intense while nested in a completely dry air environment. In fact, when Charley first developed, he was totally surrounded by a deep layer of African Dust. It is thought this may have contibuted to the small size of the Hurricane.

For such a fast forward speed, and a surrounding dry air environment, this hurricane found a small nest and took it along for the ride. Also of note...the eye of Charley contracted further while moving through Charlotte Harbor. It is possible that the eye iteslf was less than 2 miles wide (maybe 1.5 miles wide) at final landfall in Punta Gorda.

90% of tropical cyclones develop from tropical waves that move off the coast of Africa. That does not make them a Cape Verde system.

The official definition of a Cape Verde tropical cyclone is one that develops near the Cape Verde Islands, or within 800 miles (if I remember correctly). Taking a look at Charley's path, it developed outside of that.



I guess you could not consider it a Cape-Verde type nor a homegrown type.

I disagree. With a drought in West Africa we should see dust choked Tropical Waves that will take longer to develop. We should see more waves make it across the Atlantic before they shake the dust out & form. This was key in like 2005. Should add to the homegrown advantage.

Barefoot~ NHC renamed TD10 because it tangled with a shortwave or something as it regenerated. This is another argument to calling it homegrown.

It's a term you would use to describe a storm that formed in the Western North Atlantic, kinda closer to land. Usually either a cut off low or a Tropical wave interacting with a cutoff low, shortwave or other bit of energy. Usually something not 100% African wave.

Charley for example..TD just east of the islands. All Tropical wave straight from Africa. I wouldn't call it homegrown either. They are mostly born in SW or W Caribbean, GOM, Bahamas or along the east coast.

TROPICAL LOW 17U
11:27 AM CST March 12 2012
=======================

At 9:30 AM CST, Tropical Low (1001 hPa) located at 10.3S 129.8E has 10 minute sustained winds of 25 knots with gusts of 45 knots. The tropical low is reported as moving west at 4 knots.

There is the possibility of a cyclone developing but GALES are not expected in coastal areas within the next 24 hours, however gales could develop later.

The Territory Controller advises communities under Watch that now is the time to put together your emergency kit, clear your yards and balconies, and commence home shelter preparations.

Residents of Darwin and Rural Areas are advised that if you DO NOT have accommodation constructed to the Building Code or are unsure of your present accommodation you should determine which public emergency shelter to use. This advice is issued to allow you sufficient time in which to take the necessary precautions before winds reach a dangerous level.

Tropical Cyclone Watches/Warnings
========================

A Cyclone WATCH has been declared for a developing tropical low for coastal areas from Cape Hotham to Kalumburu including Darwin and the Tiwi Islands

One year after catastrophe, Fukushima remains a threat

"Reactors are still in meltdown"

Stéphane Lhomme, head of the French anti-nuclear organisation l’Observatoire nucléaire, says that TEPCO is seriously playing down potential dangers. “Their declarations are over-confident, and moreover, simply not true,” he told FRANCE 24. “The plant is neither stable nor fragile.” Lhomme describes the current situation as “catastrophic. Even if the thermal power in the four damaged reactors has been considerably reduced, they are still in meltdown and therefore still noxious.” Speaking with an alarmed tone, he says “of course the global situation is slightly better than it was a year ago. But the corium, a lava-like fuel-containing material that lies at the bottom of the containers, remains a real problem.”

I wouldn't call him "homegrown" either, but it is incorrect to say that he had Cape Verde origins. I get what you're saying; the incipient tropical wave emerged off western Africa, and thus originated near the Cape Verde Islands. But unless a tropical cyclone develops in that general area, it is highly erroneous to label such systems as having Cape Verde origins. Because going by that logic, we'd have to consider every tropical cyclone that forms from African easterly waves as Cape Verde systems.

A Coronal Mass Ejection (CME) is now seen in the latest Lasco C2 images off the southeast limb. This explosion is most likely the result of a filament eruption. This should have no impact on Earth as it is will probably be directed to the south and east.

I don't think there is an official definition for homegrown development, it's just a term used here on Wunderground and other weather forums. That includes tropical depressions and storms.

Quoting Skyepony:
Barefoot~ Katrina is a great example of my point. The dust & shear kept the wave weak. It didn't step off Africa, blow up & become fatally attracted to the North Pole, re-curving out to sea. It was a tropical wave that mixed with some moisture & energy off FL, formed over the Bahamas, used the curvature of the coast of FL to strengthen as well as the moisture & heat from it as it crossed. It was homegrown in those 'cane breeding grounds just east of FL.

I see what you're sayin'. I don't remember where the CV wave became TD10. Some at wu were of the opinion TD10 regenerated and was re-named TD12 by NHC. Anyways, I guess we don't have a firm definition for "homegrown" related to Atlantic TCs or, if we do, I don't understand it yet. lol

Love that expression you used, "become fatally attracted to the North Pole."

Quoting HurricaneDean07:

though on another topic about the disaster, Tepco was lying about the fukishima information at times, and that puts egg all over their face becuase all that does is hurt them and their reputation in the end... especially with other countries that couldve been possibly affected it the wind had shifted toward another country like Korea or Russia.. I don't know really, it just seems that the government really doesn't have to hide stuff like that just becuase they're afraid of releasing the info, or afraid we'll go nuts and become paranoid.. the truth of the fact is that all it does is make them untrustworthy... and thats all I gotta say about the subject. Might tune back in later on.


Yes, there is some proof that both Tepco and the Japanese government were made aware of the tsunami danger before the reactors were built and decided to disregard that information.

In the near geological record there was a tsunami which would have breached the reactor sea walls.

And it's possible that Tepco/the government was lying at times during the disaster. I've not seen a careful analysis. I did observe at times information had to be corrected as events were unfolding. Was that due to things not being clear or outright lies, I don't know

But hiding a piece of information that was not publicly released and somehow keeping thousands of missing people secret is not comparable.

2005: Busy, Strong Cape Verde Year. Notice warmth in the east...


2006: Quiet, Close to home year... notice the warmer gulf...


2007: Active on both ends, warm in the west and east...


2008: Busy Cape Verde year. strong storms formed in the carribbean and east...


2009: Very cold, cuase of the nino... warmer gulf overall though.


2010: Very similar to 2005, it was significantly warmer out east. many cape verde storms...


2011: More of both ways, kinda warm east, sorta warm rest, and im sure you guys have at least a good enough memory to know what happened last year... I hope.


2012: and today's sst map, warmer west, and very cool east, which in turn would result in more pop-up, out of the blue monsters... just an assumption, doesn't many anything toward what will happen during the season...


I hope you get the picure, cause it took a lot of blog page space... sorry for post-bombing, everyone...
Nice work, I appreciate the effort for comparison, and one of the more interesting posts I've seen on here lately.
