Hurricane center tracks newly formed subtropical storm in Atlantic

The 2020 hurricane season has another formed system on its hands as Subtropical Depression Four continued to churn Tuesday in the north Atlantic off the coast of Canada.

The system that formed with sustained winds of 35 mph is located in the north Atlantic about 360 miles south of Halifax, Nova Scotia or 670 miles southwest of Cape Race, Newfoundland, according to the 11 a.m. update from the National Hurricane Center.

The storm is moving east-northeast at 13 mph, and there are no coastal watches or warnings in effect.

“Little change in strength is forecast during the next day or two, but the depression is expected to degenerate into a remnant low on Wednesday and dissipate by early Thursday,” forecasters said.

If its wind speed were to exceed 39 mph, the system would be named Subtropical Storm Dolly.

Subtropical cyclones generally form over colder waters, but also can have circulation center that’s much a much wider radius than a tropical system, with a less symmetric wind field and distribution of convection.

The 2020 hurricane season has already seen three named storms, with two early systems, Tropical Storm Arthur and Tropical Storm Bertha forming in May. Tropical Storm Cristobal formed from a system that developed on the first day of the official season, which runs from June 1-Nov. 30.

The 2020 hurricane season names are: Arthur , Bertha, Cristobal, Dolly, Edouard, Fay, Gonzalo, Hanna, Isaias, Josephine, Kyle, Laura, Marco, Nana, Omar, Paulette, Rene, Sally, Teddy, Victy and Wilfred.
