Numerous gale-force wind gusts in association with showers and thunderstorms were observed in the Florida Keys and adjacent coastal waters, primarily during the evening of July 17th through the morning of July 18th.  Strong high pressure along the U.S. east coast in combination with slightly cyclonic flow across the western Caribbean Sea, in combination with above-normal moisture content, enabled regeneration of showers and thunderstorms during the nighttime hours.
