An out-of-season subtropical storm could form this week in the Atlantic Ocean.

If it forms, it will be named subtropical storm Owen. The storm has shown the beginning signs of a subtropical storm with a lower pressure system and disorganized thunderstorms north of the Leeward Islands.

The Leeward Islands are located about 350 miles southeast of Puerto Rico.

"A large area of low pressure located over the central subtropical Atlantic about 800 miles northeast of the northern Leeward Islands continues to produce a broad area of showers and thunderstorms," the National Hurricane Center warned.

"Environmental conditions appear marginally conducive for development and a subtropical or tropical storm could form in the next couple of days," it added.

The Ocean Prediction Center issued a storm warning for waters within several hundred miles of the system and the system being monitored is moving eastward at 6 mph. It could intensify within the next 48 hours.

On Wednesday, the pressure could drastically drop, alongside 46-57 mph winds.

Subtropical storms are different than tropical storms due to "subtropical cyclones originate over tropical or subtropical waters and have a closed circulation about a well-defined center. In comparison to tropical cyclones, the maximum winds occur relatively far from the center," according to the National Weather Service.

AccuWeather Senior Meteorologist Adam Douty noted the potential severity of the storm.

"This tropical system is expected to be large, spanning hundreds of miles. As a result, wind and rough seas can extend well away from the center of the storm," Douty said.
