The storm is way out in the Atlantic ocean - 815 miles west of the Azores with maximum sustained winds estimated at 45 mph.
The unusual storm is expected to be short-lived, dissipating today as it is absorbed by a large mid-latitude low-pressure system.
Now there's Tropical Storm Arlene.
The 2017 tropical outlook will be updated again on June 1st but at this point we can be guaranteed of at least 1 named storm in 2017.
April tropical systems are pretty rare, but not unheard of.
During the past few days, the Atlantic Ocean has shown some signs of tropical activity, with a small subtropical depression forming on Wednesday.
Storms have formed even earlier than April. That storm eventually became a hurricane.
So, is this a sign of how the 2017 Hurricane Season might play out? "The only exception is if we get tropical cyclone activity in the deep tropics prior to August 1". Hurricane Alex formed in the north-central Atlantic in January of 2016.
Hurricane season runs from June 1 to November 30, but a year ago two storms formed before the official start of the season. In fact, storms have formed before June 1st in four of the last six years.
