Invest 91L Could Become Subtropical Storm

Posted by on Wednesday, April 19, 2017

The National Hurricane Center has given a non-tropical low pressure system located over the central Atlantic a 70 percent chance of becoming a subtropical cyclone during the next day or so.

The low is centered more than 1000 kilometres southwest of the Azores.

Showers and thunderstorms have become a little better organized over the past 24 hours.

Winds to near gale force have developed northeast through southeast of the well-defined center.

There is a limited opportunity to develop. The system will be absorbed by a larger extratropical cyclone on Thursday.

On its current track the system poses no threat to land.

Should the storm be named it would be called “Arlene”, this would also be the first time that a storm has formed in April since 2003.
