Tropical Storm Arlene forms in Atlantic; it's no threat to land
Tropical Storm Arlene formed April 20, 2017, far out in the Atlantic Ocean.
"Tropical storms in April are rare and Arlene is only the second one observed in this month during the satellite era," he added. The satellite era began in the early 1960s. "It should be noted, however, that this type of storm was practically impossible to detect prior to the weather satellite era."
Arlene is also the farthest north a tropical storm has formed in the Atlantic so early in the season.
