Subtropical Storm Josephine expected to bring high surf and coastal flooding along the Atlantic seaboard

The National Hurricane Center has named an October nor'easter Subtropical Storm Josephine as it moves northeastward offshore. Forecast models suggest the system could strengthen to sustained winds of about 80 mph on Friday, with the strongest winds and rain staying over water.

Coastal officials have issued flood alerts for the Outer Banks of North Carolina, where inundation of 1 to 4 feet is possible, and high surf advisories for waves up to 14 feet. Similar conditions are expected along parts of the Virginia, Maryland, Delaware and New Jersey coasts, with potential inundation of up to 2 feet and waves reaching 10 feet. River gauge levels from North Carolina to Maryland may rise to moderate flood stage at high tide.

Rip currents are forecast to pose hazards along the Atlantic beaches from Florida to New England, and beach erosion is likely throughout the region. While the storm’s heaviest rain will remain offshore, occasional showers could affect coastal areas, and gusts may down power lines in some communities.

"The area most likely to see prolonged coastal flooding is from the Delmarva Peninsula to eastern North Carolina," officials warned.

Overall, authorities advise residents and beachgoers to monitor local advisories and take precautions against surf and flooding hazards.
