Hurricane season, "above normal" 1:43
The hurricane season could begin before its official start for the seventh consecutive year in the Atlantic Ocean, as the National Hurricane Center (NHC) monitors a developing weather system that could become the first. named storm this season.
On Wednesday morning, the center recognized a region in the North Atlantic Ocean, northeast of Bermuda, as an area to observe subtropical development.
This meteorological system has a low probability of 30% of formation in the next five days.
If it becomes a tropical or subtropical storm, it will be called Ana.
Water temperatures are cold enough for a tropical cyclone to form, so if it does form, it would likely be classified as a subtropical cyclone.
Regardless of whether this system becomes a tropical or subtropical cyclone, there will be no significant impacts on land.
Downpours and gusty winds are possible at the end of the week and over the weekend in Bermuda.

The preseason activity is not too unusual
This possibility of development indicates that the hurricane season is just around the corner and that the time to observe the Atlantic Ocean for tropical systems is beginning.
The Atlantic hurricane season begins on June 1 and lasts for six months, until November 30.
In the last five years, however, tropical cyclones have formed before June 1.
Last year, two tropical storms, Arthur and Berry, were named ahead of the official start date.
The last time the name Ana was used was in 2015, also before the start of the hurricane season.
Ana became a tropical storm in early May 2015 and made landfall near Mrytle Beach, South Carolina.
"Named storms have formed before the official start of the hurricane season in about half of the past 10 to 15 years, including each of the past six years," said Dennis Feltgen, NHC public affairs and communications officer. .
What to do in the event of a hurricane
Many of the May systems are short-lived hybrid (subtropical) systems that are now being identified due to better monitoring and policy changes that are now named subtropical storms, ”Feltgen added.
This has prompted the National Hurricane Center to begin issuing its Tropical Weather Outlook on May 15 instead of June 1.
The Tropical Weather Outlook is issued four times a day, highlighting areas to watch out for for the possible development of a tropical storm or depression.
"These prospects provide a warning alert that NHC is monitoring one or more disturbances that have the potential (low, medium high) for tropical cyclone development over the next 48 hours and five days," Feltgen told CNN.

The first named storm generally doesn't form in the Atlantic until July 9, according to the NHC.
It is not until mid-August that the first hurricane usually forms.
August, September and October are the most active months for tropical storms and hurricanes.
Early outlooks for the 2021 Atlantic hurricane season predict that activity will once again be above normal.
The National Hurricane Center will release its official forecast for the 2021 Atlantic hurricane season on Thursday.
