Sub-tropical depression 01 has formed in the north Atlantic, although is expected to be short lived and remain away from land areas…well offshore between Bermuda and the Azores

Here’s the latest satellite image of this out of season system

Here’s what the various computer models are showing for this sub-tropical cyclone

Subtropical Depression One is the first April system since 2003. Since 1851, only seven tropical systems have formed before May 9th.

This makes the third straight year that a system has formed in the Atlantic…before the official June 1st start of the hurricane season.

TC Ana back in 2003 was the last April named storm in the Atlantic Basin. Ana began as a sub-tropical storm on April 20, 2003, and soon gained full tropical characteristics. That made Ana the only tropical storm on record to form in the Atlantic Basin in April.

According to the National Hurricane Center (NHC), the non-tropical low over the north central Atlantic, which has been tracked by NHC for the past few days, has developed organized convection mainly in a curved band southeast of the center.

The system is still embedded within an upper level low pressure system, while the outflow is minimal and the strongest winds are removed from the center of circulation.

Consequently, the low is being classified as a subtropical depression, with an initial intensity of 30 knots (35 mph).

It’s anticipated that shear and cold waters will not allow intensification, and the subtropical depression is expected to become absorbed by a large extratropical cyclone in about 36 hours or sooner.

A gradual turn to the north and north-northwest around the approaching extratropical low is forecast for the next 24 hours or so.
