The 1966 Atlantic hurricane season featured the tropical cyclone with the longest track in the Atlantic basin – Hurricane Flossie. Also during the year, the Miami, Florida Weather Office was re-designated the National Hurricane Center. The season officially began on June 1, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was a near average season in terms of tropical storms, with a total of 13 named storms. The first system, Tropical Depression One, struck Mexico in late May. The second system, Alma, developed over Nicaragua on June 4th, and later eventually struck Florida as a category 4 hurricane, becoming the most intense June hurricane by a large margin.

Hurricanes Becky, Celia, Daisy, and Tropical Storm Ella all did not strike land. Flossie took a long trek through the entire Atlantic ocean, forming near Cabo Verde, peaking near the Lesser Antilles, and eventually dissipating over Norway, the only tropical cyclone to exist north of Scotland. Greta was another non impactful storm, while Hallie hit Mexico as a weak storm. Inez traversed the Caribbean as a category 5, causing devastation along the way, becoming the deadliest storm of the season. Judith and Kendra all did not impact land in major ways, while Hurricane Lois in early November did not impact land at all. The final storm of the season, Tropical Storm Marsha, hit the East Coast on December 12th - 13th, as a 60 mph tropical storm. Overall, the storms of 1966 caused $953 million in damages, with a majority of the damage toll coming from three storms - Alma, Flossie, and Inez. The death toll of the season was 1437, with most of it caused by Inez.
