 A tropical wave moved off the west coast of Africa on September 3 and was designated as Tropical Storm Dog by the Air Weather Service in real time on the following day . The cyclone tracked a general westward path for much of its initial stages as it gradually intensified , reaching tropical storm intensity shortly after development and then hurricane intensity a day later . After reaching a longitude roughly equal to that of the Lesser Antilles , Dog began to curve northward on a parabolic track , bringing it near Bermuda at peak intensity as a Category 4 hurricane on September 13 . The hurricane then began to accelerate northeastward and weaken . The waning Dog grazed Cape Race , Newfoundland , before transitioning into an extratropical cyclone on September 15 ; these remnants persisted for an additional day .
