Hurricane Florence produced strong swells and dangerous surf conditions for the northern Lesser Antilles, U.S. Virgin Islands, Puerto Rico, Hispaniola, and Bermuda. Later in its duration, the tight pressure gradient between Florence and a high-pressure system over southeastern Canada produced strong winds and rough waves along the East Coast of the United States. The hurricane also caused strong swells and rough ocean conditions, including rip currents, in the Bahamas and Atlantic Canada.
