Subtropical Storm Josephine forms in Atlantic as it heads up East Coast

Key Points:

• Subtropical Storm Josephine formed in the Atlantic and is moving up the East Coast toward Cape Cod, currently located about 265 miles south of Nantucket with sustained winds of 65 mph.
• The storm developed tropical characteristics as it moved over the warm Gulf Stream waters and is forecast to move north-northeast before accelerating away from the East Coast by Friday, potentially affecting Atlantic Canada briefly.
• Gusty winds are expected across parts of the Northeast starting Wednesday evening through Thursday, with Long Island and eastern Massachusetts seeing gusts of 30-40 mph, and Nantucket and Martha’s Vineyard potentially experiencing gusts over 50 mph.
• Showers are possible in Cape Cod and Rhode Island, but rainfall totals are expected to be low, with wind and rain subsiding by the weekend.
• Josephine is causing coastal flooding along parts of the East Coast, with moderate flooding potentially persisting in the Chesapeake Bay area into Thursday or early Friday, while most other areas saw their last coastal flooding during Wednesday afternoon’s high tide.
