The National Hurricane Center has issued a special Tropical Weather Outlook, giving a system in the Central Atlantic a 30 percent chance of development.
This is the first special outlook issued in 2017 by the center. Scheduled outlooks begin June 1, the first day of Hurricane Season.
The storm, which would be named Arlene if it develops, is considered a non-tropical low pressure system and is no threat to land, but is notable just for its appearance before the official start of the season.
Dennis Feltgen, a spokesman for the National Hurricane Center, said the system has the potential to become a sub-tropical cyclone.
“This low is currently producing only limited shower activity, but environmental conditions could favor additional development and this system has the potential to become a subtropical cyclone over the next day or so as it moves generally eastward,” forecasters wrote.
While this is the first outlook issued, the hurricane center was monitoring a system in March that fizzled before it developed.
Last year, January’s Hurricane Alex formed from a sub-tropical system in the Atlantic. Alex, which formed Jan. 14, was the second January-born Atlantic hurricane on record.
