What was once Subtropical Depression Four strengthened into Tropical Storm Dolly on Tuesday. This makes it the fourth named storm of an already busy Atlantic Hurricane season.
“The wind field has contracted to make Dolly no longer a subtropical system,” says CNN meteorologist Dave Hennen.
Satellite-derived wind data shows that the storm has strengthened to 45 mph, the National Hurricane Center said in a special update.
This is the third time this decade a “D” named storm has formed this early in the Atlantic, says CNN meteorologist Taylor Ward.
“Dolly has formed in the North Atlantic—the 3rd earliest 4th Atlantic named storm formation on record (since 1851),” tweeted Colorado State University research scientist Phil Klotzbach.
#Dolly has formed in the North Atlantic – the 3rd earliest 4th Atlantic named storm formation on record (since 1851). Danielle is earliest on 6/20/2016. Debby is 2nd earliest on 6/23/2012 at 12 UTC. Dolly in 2020 formed on June 23 at 1615 UTC. #hurricane pic.twitter.com/1Ha6ZnxHqc

The storm is 370 miles south of Halifax, Nova Scotia.
“The good news is that the storm is expected to be around for only a brief period of time and is moving away from the US into the open waters of the North Atlantic,” Ward said.
All the models agree that if Dolly continues to move east-northeast and will turn more northeastward later Tuesday. Later, Tuesday afternoon or evening, the storm should begin weakening.
The low should then dissipate by early Thursday, the National Hurricane Center said.
