Tropical Cyclone Iota was the thirty-first and most powerful tropical cyclone of the 2020 Atlantic Hurricane Season, overtaking in intensity the recent Hurricane Eta. Iota developed from a powerful tropical wave moving across the eastern Caribbean Sea, which evolved into a tropical depression on 13 November. Six hours later, it strengthened into a tropical storm while it was over the central Caribbean Sea, north of Colombia. In the following days Tropical Storm Iota intensified, becoming a major hurricane on 16 November.

On 2 November, Tropical Storm Eta rapidly intensified, becoming a major hurricane, and on 3 November it made landfall in Nicaragua as a category 4 Hurricane. Hurricane-force winds and catastrophic storm surge were experienced near the landfall point. While moving across Nicaragua, Eta rapidly lost intensity, being downgraded to a tropical storm on 4 November and to a tropical depression on 5 November, when it left the country heading for Honduras. During this period, tropical-storm-force winds extended over a large part of Nicaragua.
