MIAMI (AP) — Subtropical Storm Josephine remained offshore Thursday but was bringing impacts including coastal flooding and gale-force winds to the Eastern Seaboard.
Large swells that could create life-threatening surf and rip current conditions were possible along the coast up to Atlantic Canada, the U.S. National Hurricane Center said in an advisory.
Josephine had maximum sustained winds of 65 mph (100 kph). The subtropical storm was centered about 200 miles (322 kilometers) southeast of Nantucket, Massachusetts, and about 420 miles (676 kilometers) south-southwest of Halifax, Nova Scotia. It was moving northeast at 12 mph (19 kph).
The Miami-based hurricane center said Josephine was forecast to continue moving away from the United States and remain south of Nova Scotia and Newfoundland. Josephine was expected to gain strength and become a powerful extratropical cyclone with hurricane-strength winds by Friday.
The National Weather Service posted a gale warning for parts of the Northeast and mid-Atlantic, meaning winds above 39 mph (63 kph) were possible through midmorning Friday. Small watercraft were also advised of hazardous conditions south to North Carolina's Outer Banks.
Minor to moderate coastal flooding was also expected to continue through the week on the mid-Atlantic coast.
In the Pacific, Tropical Storm Vance was well off Mexico's southwestern coast and may intensify to a major hurricane by the weekend.
It had maximum sustained winds of 60 mph (97 kph) early Thursday and was forecast to become a hurricane by the end of the day, the hurricane center said.
Vance was located about 505 miles (815 kilometers) south of Acapulco, Mexico.
