Tropical Storm Don didn't last long, but did manage to become a relatively early fourth named storm and did lead to some flash flooding in a few areas. Don became the fourth named storm of the 2017 Atlantic hurricane season on July 17, as it was about 500 miles east of Barbados, after a hurricane hunter mission found a small low pressure circulation with winds of tropical storm force. Within 36 hours of becoming a named storm, Don sputtered out.
