Subtropical Storm Josephine formed in the Atlantic on October 21, 2026, located about 265 miles south of Nantucket, Massachusetts, with maximum sustained winds of 55 knots and gusts to 65 knots. The US National Hurricane Center forecasts Josephine to strengthen further before moving northeastward away from the United States and transitioning into a powerful extratropical cyclone. GDACS estimated that roughly 7.5 million people are within the storm's tropical-storm-force wind field, though no one is expected to experience category 1 hurricane-force winds. The storm affects the United States, Canada, and Saint Pierre and Miquelon, with low vulnerability reported. The NHC issued multiple advisories through the evening as the storm's structure evolved.
