Nov. 30 marked the conclusion of the Atlantic hurricane season, but the basin is on the verge of churning out a subtropical storm this week -- an uncommon feat if it occurs.

Despite the fact the hurricane season ended last month, forecasters with the U.S. National Hurricane Center (NHC) are keeping a close eye on the Atlantic basin this week for a rare, potential subtropical storm to develop.

The NHC recently issued a special tropical weather outlook for the potential development. In the next 48 hours, there is a 50 per cent chance of tropical formation.

If the system does become a subtropical storm, it will be named Owen -- the next entry in the 2022 list.

Also, if it does, it will be quite the accomplishment as the last storm that developed in December happened in 2013, an unnamed system. The NHC did a re-analysis of the 2013 disturbance, concluding that a short-lived low that developed south of the Azores during early December was a subtropical storm.

The most recent hurricane to occur in December was Epsilon in 2005.

Here is what the NHC has to say about the current system:

A large area of low pressure located over the central subtropical Atlantic, about 1,287 km northeast of the northern Leeward Islands, is producing a broad area of showers and thunderstorms. Environmental conditions appear marginally conducive for development and a subtropical or tropical storm could form in the next couple of days.

By Thursday night or Friday, the low will move northeastward over cooler waters and interact with a mid-latitude trough, limiting subtropical or tropical development of the system.

So there will be a short window for development.
