Part of the 2020 Atlantic hurricane season

Hurricane Iota was a devastating late-season Category 4 Atlantic hurricane which caused severe damage to areas of Central America already devastated by Hurricane Eta just less than two weeks prior. The 31st and final tropical cyclone, 30th named storm, 14th hurricane, and record-tying seventh major hurricane of the record-breaking 2020 Atlantic hurricane season, Iota originated as a tropical wave that moved into the Eastern Caribbean on November 10. Over the next few days, the wave began to become better organized and by November 13, it developed into a tropical depression north of Colombia. The depression strengthened into Tropical Storm Iota six hours later. The storm was initially impacted by some wind shear, but a center relocation and relaxed shear allowed Iota to quickly strengthen into a hurricane on November 15, after which it underwent explosive intensification, peaking as a high-end Category 4 storm, with wind speeds of 155 mph (249 km/h). After weakening slightly, Iota made landfall in northeastern Nicaragua as a mid-range Category 4 hurricane, becoming the strongest recorded hurricane to make landfall in Nicaragua in November. Iota then rapidly weakened as it moved inland, dissipating on November 18.

Iota's precursor disturbance generated flash flooding on several Caribbean islands. Tropical cyclone watches and warnings were first issued on November 14 in parts of Colombia, Nicaragua, and Honduras, with the latter two countries still recovering from Eta. Heavy rains associated with a tropical wave and Iota brought heavy rainfall to parts of Colombia, leading to flash flooding and mudslides. Extremely heavy rain fell on much of Nicaragua, widening flash flooding caused by the hurricane's high storm surge. Mudslides caused extensive damage and multiple deaths. At least 67 people were killed due to Iota, including at least 28 in Nicaragua and 16 in Honduras, among other countries.[1][2][3][4] As many as 41 people were reported as missing. The preliminary estimate for the damage in Nicaragua was $564 million (2020 USD).[5] Total damage estimates for the hurricane were set at $1.4 billion (2020 USD).[6]

Relief efforts soon followed, which included placing tents, opening temporary hospitals, and delivering food and water to those in need. Numerous power outages were restored in the days that followed. Donations worth hundreds of millions of USD were given to affected countries. An estimated total of 5.2 million people were affected by the storm.[7]
