Unusual far north formation

#1 Postby Downdraft » Tue Jul 31, 2007 10:01 am

Isn't it highly unusual for a tropical system to form so far north? Anyone know the farthest north a system has ever formed?

We will have to wait until the post-season because I believe they would include more southern positions of the storm as a subtropical cyclone.

Don't go far into history, just last year!!!

Upon transitioning into a tropical cyclone at 39.1º N, the storm broke the record for the northernmost cyclogenesis in the Atlantic in July since reliable records started in 1940, surpassing that of Tropical Storm Arthur in 2002. It was also the northernmost tropical or subtropical cyclogenesis for an Atlantic tropical cyclone since a subtropical storm in December of 1975. Additionally, the cyclone became a tropical storm further north than any other Atlantic tropical cyclone in the month of July, and was further north than any other Atlantic storm since Tropical Storm Alberto in 1988.[5]

The Canadian hurricane center has an area of responsibility?

No, they just follow what the NHC says.

Mostly Canada's territorial waters.

Upon entering the area of responsibility of the Canadian Hurricane Centre, a Canadian buoy recorded maximum sustained winds of 36 mph (56 km/h) with gusts to 44 mph (70 km/h).

Slight error then on WP.

What's the error, exactly? They DO have an area of responsibility, which is Canada's territorial waters.

This is incorrect. The Canadian Hurricane Centre is responsible for warning for Canada's waters and do differ from NHC at times.

But do they issue their own tropical cyclone advisories? Because what you are referring is just territorial waters, every country with a meteorological office does that.

Yes, they do.

Their latest Chantal advisory:

http://www.atl.ec.gc.ca/weather/hurricane/bulletins/20070731120427.Chantal.txt.en

They're a hurricane centre, not just a national meteorological service (for Canada, Environment Canada), so yes, they do issue bulletins.
