What it means here

Josephine is under advisory at 310 miles, and nothing in our forecast window crosses the groundswell threshold. A named storm in the Atlantic is not the same thing as surf in New Jersey.

Watchlist

  • Updated70%

    Shower and thunderstorm activity has become better organized in association with a storm-force low pressure area located a few hundred miles off the mid-Atlantic United States coast. The system has continued to acquire subtropical characteristics today and has become separated from fronts. If these trends continue, a subtropical storm could form later this afternoon or tonight while it accelerates

    70% within 48 hours

  • Atlantic10%

    A trough of low pressure located several hundred miles east-southeast of Bermuda is producing a large area of disorganized showers and thunderstorms. Some development of this system is possible during the next day or two while it moves slowly north-northeastward. Upper-level winds are forecast to become too strong for further development by the weekend.

    10% within 48 hours

Chance of formation within 7 days, as published by the National Hurricane Center. Not a forecast of surf for New Jersey.
