Tropical Storm Leslie hits Newfoundland; TD 14 forms

Tropical Storm Leslie zoomed ashore over Newfoundland this morning near 8 am EDT, traveling with a forward speed of 40 mph. Leslie brought sustained winds to the capital of St. Johns of 58 mph, gusting to 82 mph, at 10:30 am local time. At least three other stations in Newfoundland recorded gusts over hurricane force: Cape Pine (85 mph), Bonavista (77 mph), and Argentia (74 mph). Damage to buildings has been reported in St. Johns, and the storm has knocked out power to much of Southeast Newfoundland, including the capital. Leslie's tropical moisture collided with the cold front drawing the storm to the north, resulting in heavy rains over Nova Scotia in excess of 4 inches, which caused considerable flooding of homes and streets. Overall, though, the damage to Canada appears to be far less than that of Hurricane Igor, which hit Newfoundland as a Category 1 hurricane in 2010, causing $200 million in damage. Leslie has now transitioned to a powerful extratropical storm, and will bring heavy rains to Iceland on Thursday, and to Scotland on Friday.


Figure 1. Tropical Storm Leslie as it crossed Newfoundland at 9:46 am EDT September 11, 2012. At the time, Leslie had top winds of 70 mph. The cloud pattern of Leslie looks more extratropical than tropical, and Leslie was no longer a tropical storm at this time. Tropical Storm Michael is visible at lower right, as a tight swirl of low clouds.

Hurricane Michael dying
The longest-lived hurricane of the 2012 Atlantic hurricane season was Michael, which attained hurricane status at 11 pm EDT September 5 and finally weakened to a tropical storm at 5 am EDT this morning. Satellite loops show that Michael has lost almost all of its heavy thunderstorms, and is racing to the northeast over colder waters. Michael will likely be declared dead later today.

Tropical Depression 14 forms
Tropical Depression Fourteen has formed midway between Africa and the Lesser Antilles Islands, from a tropical wave that emerged off the coast of Africa on Friday. The models unanimously predict that TD 14 recurve to the north well east of the Lesser Antilles Islands later this week, on a track that would likely keep this storm far out at sea away from any land areas. TD 14 is in a low-shear environment favorable for strengthening, and will likely become Tropical Storm Nadine by Wednesday.

Elsewhere in the Atlantic
The ECMWF model predicts that the cold front that swept off the U.S. East Coast Monday will leave a trough of low pressure over the ocean which could serve as the focus for development of a tropical or subtropical depression several hundred miles off the coast of North Carolina late this week.

Iniki completed a “clean sweep” of National Weather Service offices responsible for issuing hurricane warnings. The National Hurricane Center in Coral Gables, Florida (Hurricane Andrew), the Joint Typhoon Warning Center in Guam (Typhoon Omar), and the Central Pacific Hurricane Center in Honolulu, Hawaii (Hurricane Iniki) were all struck by strong hurricanes within a 2-month span in 1992.

20th anniversary of Hurricane Iniki
Twenty years ago today, Hurricane Iniki, the most powerful hurricane on record to strike the state of Hawaii, made landfall on the island of Kauai as a Category 4 storm with sustained winds of 145 mph and gusts up to 175 mph. Iniki brought storm tides of 4.5 - 6 feet (1.4 - 1.8 m) to Kauai, with high water marks of up to 18 feet (5.5 m) being measured due to large waves on top of the surge. Waves up to 35 feet (10.5 m) battered the southern coastline for several hours, causing a debris line of more than 800 feet (250 m) inland. The hurricane's high winds did incredible damage to structures on the island--5,152 homes were severely damaged, and some parts of the island were without power for three months. Iniki's $3 billion damage (2012 dollars) made the hurricane the second costliest Eastern Pacific hurricane, trailing Hurricane Paul, which made landfall in Mexico in 1982. Iniki holds the Eastern Pacific record for lowest pressure for a landfalling hurricane--945 mb (27.91").

I was looking at that, I think the stalled car movement was actually from the wake of the passing car... Didn't hear any metal to metal contact, but definitely heard him hit that poor palm tree!

It is hard to exactly see but you can clearly see the palm tree hit.

A quick forecast that wraps -up my thoughts for now, this could change in the morning.

I'll have the regular blog update in the morning, which I now do everyday. Over the weekend I'll have the normal tropical blogs plus a blog about Isaac and the Saffer Simpson scale and one on the season so far and past peak predictions by me.

Your family must have been hilarious. They ignored you because you were little. The advantage of being the youngest is, if nature takes it course, that you will have the last laugh.

Here is the one in Central Africa.




Just in from under that land blob..

Disaster hit Makurdi, Benue State capital and several communities in the state, yesterday, as an unprecedented surge of River Benue swept away several houses, leaving thousands of people homeless with property worth billions of naira washed away. The surge which started building up Sunday night had at the last count, submerged close to 10,000 residential houses, business places, huts and farmlands. Worst hit by the devastation were houses within the bank of the river and most structures within five kilometres radius of the river. Some of the affected communities included: Kucha Otebe, Gyado Villa, brick factories in Wadata and New Garage, the abattoir along the new Makurdi Bridge, North Bank and the highbrow Judges quarters area of the town where Senate Minority Leader, Senator George Akume and Minister of State, Trade and Investment, Dr. Samuel Ortom have their residential houses. Also threatened by the steady rise in water levels is the main campus of the Benue State University and the newly constructed Benue University Teaching Hospital; the Regional Headquarters of the Redeemed Christian Church of God, RCCG, all in Makurdi. The flood also sacked most of the students of the state owned Benue State University who were moving out in droves after losing most of their books and house hold items to the flood. Meanwhile the state Director of Environment at the Ministry of Water Resources and Environment, Mr. Daniel Iorshahea, has warned residents living within the banks of River Benue and other adjoining communities to immediately vacate their abode to avoid being swept away by the fast increasing water levels of the river.

Hi Groth
There is no way on Earth that everyone will like everyone.

Please go back and look at the timetable and the nature of the posts I quoted. (my posts)

Not a single yo/hiya/whats up/ Or even your question makes no sense.

Thats not a community.
Thats ....
Are you someone I always talk to?
If not....
You are not worth 10 clicks on the keypad.

I have seen where people ask a question twice,and then get a nasty response.
When someone could have spent less effort in responding.... Hi I dont know,but x.. might know.

When I post as often as I did this evening,that is willful ignoring. And from the responses I received this evening. Fewer people have me on ignore than I would think.

But I must say. WU is still very close to the community that I joined.
But Sometimes I/We/WU needs a reminder.
Thats all I wanted to work out.
Work out in my mind and in my fellow WUndergrounders.

Neither do I as those are some impressive waves. Add in some homegrown development and we got at least a few more storms.

No worries! I saw your post earlier (when I was still at work, around 4pm CST), but I had a work crisis come up, and had to handle it, then bail (before another crisis came up).
