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.

This occurred almost five weeks ahead of the average fourth named Atlantic storm date, according to National Hurricane Center statistics.

Less than 24 hours later, Don was already weakening, thanks to the twin nemeses of wind shear – the change in wind speed and/or direction with height – and dry air.

Just 36 hours after first being named, Tropical Storm Don degenerated into a tropical wave just before midnight EDT on July 18.
