The fourth named storm of the Atlantic hurricane season lasted for less than forty-eight hours, becoming a “post tropical remnant low” on Wednesday.
The technicality of this means that thunderstorms around the center of Dolly diminished, while the low pressure center moves over cooler sea surface temperatures in the northern Atlantic. While Dolly no longer exists, gale-force wind and larger waves/swells will still impact the northern Atlantic.

While short-lived, Dolly was the fourth named storm of the 2020 Atlantic basin season, and far earlier than usual. Typically, the fourth named storm of the season doesn’t take place until August 23rd, according to the National Hurricane Center’s (NHC) climatology chart.
No direct impacts to land are expected, although some choppier surf and rip currents could be an issue for parts of the New England and Canadian maritime coastlines.
