Hurricane Bonnie developed over the tropical Atlantic on August 19th approximately 675 miles east of the Leeward Islands and moved on a general west-northwest track. Bonnie gradually strengthened, becoming a hurricane early on August 22nd. Bonnie's motioned slowed to less than 10 miles an hour on the 23rd as it intensified into a category three hurricane with sustained winds of 115 mph.
After the 23rd, Bonnie moved toward the southeast United States coast in the general direction of the Carolinas. As the center neared the North Carolina coast on August 26th, the forward speed slowed to nearly stationary. The center of Bonnie drifted along the coast, with the western part of the eye moving across extreme southeast Brunswick county and over eastern New Hanover county. The center officially came onshore a short distance northeast of Wilmington during the late evening of the 26th and early morning of the 27th.. Bonnie then moved slowly over extreme eastern North Carolina, emerging off the Outer Banks near Kitty Hawk early on the 28th. After being downgraded to a tropical storm while over land, Bonnie re-strengthened into a hurricane with 75 mph winds as it moved back into the Atlantic. Bonnie weakened back to a tropical storm as it moved northeast over the Atlantic and into cooler waters. It finally lost its tropical characteristics on August 30th south of Cape Race, Newfoundland.
