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 have done this two other times.
This is the first time I have pointed out my exercise.

I've felt ignored at times to Spathy.When I'am I call it the "zombie pit".Because my peeps aren't on so there is no one to talk to.Also I noticed that when I do come on I feel like the party crasher because people scatter when I make a appearence "bloggers who names will not be mentioned".

This was an exercise to see what type of Family WU still is.

I will conduct it just a few more times.

Its all good Wash.
I was just trying to point out how WU is no longer a community. Its an overactive click.

And thank you for responding Washington. :O)
It's mainly the younger bloggers that are all about themselves.But us older ones(at least me) wouldn't mind giving advice to other bloggers if they have problems.

ATCF has it as a 40mph TS so that's what the next NHC advisory should show.

Extreme emphasis on "should".

Is it officially Nadine now? NHC doesn't have it as Nadine yet.

You know, when I got pulled out of class on 9/11 up on Long Island, I was wondering if Erin busted the front and was moving to hit NYC.. then my parents turned on the TV and I was in shock. I was standing on the roof of the second tower at a fieldtrip, 3 years before they collapsed.

ATCF has it as a TS, so it is very likely the NHC will officially make it Nadine at their 11PM advisory.

I'm sure the NHC will name this Nadine and maybe raise the intensity forecast some at 11pm.
