Residents of coastal Virginia in the colonial period (1607–1776) were very much aware of the weather. To people who lived near the water and derived much of their livelihood from the sea, a tropical storm was a noteworthy event. During a hurricane in 1749, the Chesapeake Bay rose above normal, sand spit was washed up at Sewells Point. With the help of the Great Coastal Hurricane of 1806, Willoughby Spit was formed. The area of water now located between Sewells Point and Willoughby Spit became known as Willoughby Bay.
