(WLTX) - The first tropical storm of the 2017 season has formed in the north Atlantic, in what is a rare event for one of these systems to happen this early in the year.
The National Hurricane Center confirmed Thursday afternoon that what had been a tropical depression is now Tropical Storm Arlene.
The system has winds of just 45 miles an hour, making it a weak tropical storm. The storm is expected to break apart and lose its tropical characteristics Friday.
The National Hurricane Center says this is only the second time a tropical storm has formed in April since forecasters began tracking the systems with satellites.
The official start of the hurricane season is not until June 1.
