The new storm was far east of the Leeward Islands on August 27, with no coastal watches or warnings in effect.

Tropical Storm Dolly formed over the central Atlantic on Thursday, August 27, becoming the fourth named storm of the 2026 Atlantic hurricane season.

At formation, Dolly was about 1,555 miles east of the Leeward Islands, moving west with maximum sustained winds of 40 mph, according to the National Hurricane Center. The storm was far from land, and no coastal watches or warnings were in effect.

Forecasters said the Leeward Islands could see heavy rain on Saturday and Sunday. Rain could then affect the Virgin Islands, Puerto Rico and Hispaniola from Sunday into Monday, creating a risk of flash flooding in some areas.

The National Hurricane Center expected little near-term change in Dolly’s strength. CBS News reported that the system was forecast to weaken into a tropical wave before reaching the Leeward Islands, though moisture associated with it could still bring hazardous rainfall.

NOAA has projected a below-average Atlantic hurricane season, citing El Niño conditions. Its seasonal outlook called for eight to 14 named storms, including three to six hurricanes.
