Subtropical Depression Forms in Atlantic Ahead of Official Start of Hurricane Season

FLORIDA, United States, Wednesday April 19, 2017 – The first subtropical depression of the 2017 Atlantic hurricane season has formed, before the June 1 start of the Atlantic hurricane season. The good news is that it poses no threat to land and is expected to be short-lived.

The National Hurricane Centre (NHC) in Miami said at 11 a.m. that the centre of the system which has maximum sustained winds of 35 miles per hour, had formed in the Central Atlantic between Bermuda and the Azores.

It said little change in strength is forecast today, and the subtropical depression is forecast to become absorbed by a large extratropical low tomorrow.

“A non-tropical storm will sweep in prior to the end of the week and should create a more hostile atmosphere for strengthening,” AccuWeather Hurricane Expert Dan Kottlowski said.

To become Arlene, the system’s maximum sustained winds would have to increase to around 39 miles per hour.

The Atlantic hurricane season officially runs June 1 to November 30 and tropical storm formation is very rare this early.

This system is the first subtropical or tropical cyclone in the Atlantic in April since Ana in 2003; and 2017 is the third consecutive year a system has formed in the Atlantic before the official start of the season.
