Yes, the hurricane season ended last week but a disturbance popped up in the Atlantic not near us.

Hurricane forecasters on Monday were tracking a disturbance in the Atlantic, nearly a week after the official end of hurricane season. “Welcome to December! lol”, wrote Jim Cantore, a meteorologist at The Weather Channel, on his Instagram account about the tropical outlook. The disturbance doesn’t pose an immediate threat to land, according to the National Hurricane Center. As of Monday morning, a large area of low pressure was about 750 miles northeast of the Leeward Islands and was producing disorganized showers and thunderstorms.  It has the potential to acquire some subtropical characteristics while it moves northeast during the next few days, forecasters said. The system has a 40% chance of developing into a tropical or subtropical depression within five days. The next available name is Owen if it strengthens into a tropical or subtropical storm. By Thursday, the system is expected to move over cooler waters, forecasters said, ending its chances of become a depression or storm.

Subtropical as opposed to tropical

A subtropical storm has many of the characteristics of a tropical storm, except it generally has a colder core temperature and a slightly different wind structure. It poses the same threats as a tropical storm – strong winds, heavy rain and higher tides. Subtropical storms often transition into tropical storms as they move over warmer water. The 2022 Atlantic hurricane season ended Nov. 30, but storms can form any time. Hurricane forecasters have stopped giving routine daily updates and are now issuing special advisories — like the one Monday — when something is brewing in the tropics. The next hurricane season starts June 1, 2023, but storms have formed in May for the past few years.

So, is this one charged to 2022 or an early entry to 2023?
