The first N Atlantic hurricane of the season.
Next question. Will it affect our weather?

The track is into the Canadian Maritimes.
Might spice up the baroclinic zone but not sure if it will affect our weather.
Needs to come across mid Atlantic for that.

Not quite.
Ordinarily a blocking low in the North Atlantic takes place with all tropical storms. However since the giant cyclones grew in the Southern Ocean blocking nearly all anticyclonic activity in the southern hemisphere, the sympathetic block in the NA has been absent.

Not that Tropical Storms since early May have been anything more than desultory with the resulting positive NAO and NPO.

What is actually affecting our weather is the positive AAO. Apparently it sends colder waters north by the bucketful.

What could be interesting is what would happen if it decided to leave through the Davies Straight and what it would do in the Arctic.
