Tropical Storm Dolly, the fourth named storm of the 2026 Atlantic hurricane season, formed late Thursday morning over the central tropical Atlantic between Africa and the Caribbean.

The system – previously designated Invest 96L – is expected to remain a borderline tropical storm as it heads in the direction of the easternmost Caribbean islands today, but is forecast to succumb to increasingly hostile conditions and unravel by the time it reaches the Lesser Antilles, Puerto Rico, and the Virgin Islands later this weekend.

Though Dolly’s remnants could bring squally weather and locally heavy rain to higher terrain as it crosses the islands, its quick pace should limit widespread issues and the rainfall is generally a net positive for areas of the Caribbean, which have been plagued with intensifying drought conditions this summer, in part due to the strengthening El Niño.

Dolly the storm, not the singer

In a strange coincidence, Dolly the storm was christened only two days after the passing of American cultural icon and country music legend Dolly Parton.

With the unusual timing and insensitive appearance of naming a tropical storm Dolly the week flags were lowered in honor of the late, great singer, and the National Hurricane Center issued a statement clarifying the use of the name in its first advisory for Dolly on Thursday:

“The timing of the use of the name Dolly for this storm is purely coincidental,” the center wrote. “Tropical storm and hurricane names for the North Atlantic Basin originate from six pre-determined rotating lists established by the World Meteorological Organization Region IV Hurricane Committee. The name Dolly replaced Diana after the 1990 hurricane season and was first used in 1996.”

For the crossover weather enthusiasts and Dolly Parton fans (including yours truly), the very first time a tropical cyclone was named Dolly was for a western Pacific typhoon in 1946, the same year as Ms. Parton’s birth.

Dolly not expected to reform closer to the U.S.

As we’ve discussed in the newsletter all week, some outside scenarios have depicted Dolly’s remnants trying to reform in a region of lower wind shear and unusually warm waters around the Bahamas or into the eastern Gulf for middle next week.

Though the odds were low to begin with, models decidedly dropped that scenario yesterday. Dolly should be sufficiently disrupted by its passage through the Great El Niño-driven wall of shear this weekend as its remnants hit the mountainous speed bumps of the islands – especially in places like Hispaniola – that an encore performance isn’t in the cards.
