The beginnings of this tropical cyclone were along an old frontal boundary southeast of Bermuda on the 12th. Convection increased as it moved southwest and west over the next few days. By the morning of the 15th, a low was located a couple hundred miles east of the Bahamas. By the next day, it is estimated the cyclone developed into a tropical depression 175 nm east of Nassau. The system turned to the west and west-northwest, and developed into a tropical storm on the 16th. The next day, a central dense overcast was noted, and Bob had become a hurricane as it turned northward. A deep trough over the East had picked up the storm, and it accelerated northward. Bob intensified into a major hurricane east of the Outer Banks of North Carolina, then passed over cooler shelf waters.Weakening ensued as it approached New England, clipping the east side of Long Island. It came ashore again over Block Island before striking Newport, Rhode Island on the afternoon of the 19th as a category 2 hurricane. It made a final landfall as a tropical storm late on the 19th near Rockport, Maine, later crossing Maine,New Brunswick, the Gulf of St. Lawrence, and northern Newfoundland. It crossed the Atlantic as a nontropical low in the westerlies, dissipating near the coast of Portugal on the 29th. Below is the track of this cyclone, provided by the National Hurricane Center.
