Summary

  • Josephine lost subtropical-storm status Thursday night but still carried 65 mph sustained winds about 235 miles east-southeast of Nantucket, moving northeast at 17 mph and away from the United States.
  • 7-to-12-foot waves and gusty winds continued along the New England coast, prompting a gale warning for mariners and commercial vessels through 2 p.m. Friday.
  • The storm’s outer bands had already been driving rough surf for much of the week after the system was a nor’easter just days earlier, though forecasts now show it tracking farther east over the next couple of days.
  • Josephine is the Atlantic season’s 10th named storm in a year shaped by strong El Niño wind shear, which has held the basin to just one hurricane and could make 2026 the lowest Atlantic ACE season on record since 1950.
