Hurricane Iota is currently the latest Category 5 Atlantic major hurricane on record that is impacting Central America, mainly Nicaragua just two weeks after Hurricane Eta devastated the region. The thirty-first tropical cyclone, thirtieth named storm, thirteenth hurricane, sixth major hurricane, and first Category 5 hurricane of the 2020 Atlantic hurricane season, Iota originated as a tropical wave that moved into the Eastern Caribbean on November 10. Late on November 11, the wave began to become better organized and by November 13, it became Tropical Depression Thirty-One. 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 explosively deepened, becoming a Category 5 hurricane the following day. This made 2020 the fifth consecutive season since 2016 to feature at least one Category 5 hurricane. Iota is the strongest November hurricane in the Atlantic basin since the 1932 Cuba hurricane.
The precursor wave generated flash flooding in most of the Caribbean islands. Tropical cyclone watches and warnings were first issued on November 14 in parts of Colombia, Nicaragua, and Honduras. Heavy rains associated with a tropical wave and Iota brought heavy rainfall to parts of Colombia, leading to flash flooding and mudslides. Three people have been killed and eight others are missing.
Meteorological history
At 18:00 UTC on November 8, the National Hurricane Center (NHC) began to monitor the Central Caribbean for a tropical wave that was forecasted to enter the area and potentially become a low-pressure area.[1] The wave subsequently entered the Eastern Caribbean by 06:00 UTC on November 10 and moved westward into a more conducive environment for development.[2][3] Late on November 11, the wave started to become better organized and by 15:00 UTC on November 13, it had developed into Tropical Depression Thirty-One in the southern Caribbean, tying 2005 for the most tropical depressions recorded in one season.[4][5][6] Six hours later, the system strengthened into Tropical Storm Iota.[7] After struggling somewhat due to wind shear and dry air, Iota began to rapidly intensify late on November 14, as its convection started to wrap around its center.[8] At 06:00 UTC on November 15, Iota reached hurricane status before strengthening to Category 2 status at 00:00 UTC on November 16.[9][10] By 06:00 UTC on November 16, hurricane hunters discovered that Iota had become a high-end Category 3 major hurricane.[11], making it the first time there were two major hurricanes in November. Meteorologists also found intense lightning in Iota's southwest eyewall along with hail, which is extremely rare for a hurricane given the warm temperatures that are present in those storms. In addition, hail could damage the hurricane hunter aircraft investigating the storm.[12][13][14] Just 40 minutes later, at 06:40 UTC, Iota reached Category 4 intensity.[15] At 15:00 UTC, Iota intensified further into the season's first Category 5 hurricane.[16]. This is the latest formation date of a category 5.
Current storm information
As of 10:00 a.m. EST (15:00 UTC) November 16, Hurricane Iota is within 15 nautical miles of 13°30′N 82°00′W / 13.5°N 82.0°W, about 40 miles (65 km) west of Isla de Providencia, Colombia and about 100 miles (160 km) east-southeast of Puerto Cabezas, Nicaragua. Maximum sustained winds are 140 knots (160 mph; 260 km/h), with gusts to 170 knots (195 mph; 315 km/h). The minimum barometric pressure is 918 mbar (27.11 inHg), and the system is moving west at 9 knots (10 mph; 17 km/h). Hurricane force winds extend outward up to 35 miles (55 km) from the center, and tropical-storm force winds extend outward up to 150 miles (240 km).

Watches and warnings
Template:HurricaneWarningsTable
Preparations
Tropical storm warnings were first issued for Colombia islands of San Andrés and Providencia around midday on November 14.[17] Three hours later, a hurricane watch was issued for Providencia as well as along the coast of Northern Nicaragua and Eastern Honduras with a tropical storm watch also issued for Central Honduras.[8] All of the watches were eventually upgraded to warnings with an additional hurricane watch for San Andrés as well as a tropical storm warning for south central Nicaragua.[18][19]
Impact
Venezuela
The precursor tropical wave to Iota produced heavy rain across Venezuela's Falcón, primarily in the Paraguaná Peninsula. In the Silva municipality, flooding affected 288 homes. Damage to homes was reported in El Cayude and El Tranquero. The community of Santa Ana lost electrical service. Civil Protection officials advised residents of possible flooding along the Matícora reservoir in Mauroa, the Barrancas river, and the Quebrada de Uca river.[20] Some flooding occurred in the state of Miranda.[21]
Colombia
Heavy rains associated with a tropical wave and Iota caused extensive damage in Colombia.[22] The worst damage took place in the Mohán sector of Dabeiba where landslides killed three people, injured 20, and left eight others missing.[23][22][24] Eight people were rescued from the rubble.[22] The landslides destroyed 67 homes and damaged 104 others as well as three schools. A total of 497 people were affected in the community.[24] Approximately 100 vehicles were trapped by rockfalls along a road between Dabeiba and Urabá. Flooding affected 10 municipalities within the Chocó Department; the town of Lloró was isolated after the only bridge to the community collapsed. A landslide in Carmen de Atrato killed one person when his home was buried.[23] Across Chocó, an estimated 28,000 people were affected.[24] A van with two occupants disappeared when a landslide dragged the vehicle into the Atrato River. Emergencies were declared for 29 municipalities in the Santander Department where multiple rivers topped their banks. Several families were evacuated from Cimitarra due to rising water along the Carare River. A bridge collapse along the Chicamocha River isolated approximately 1,000 people in Carcasí and Enciso. More than 1,000 homes were damaged in the Atlántico Department: 693 in Malambo, 200 in Candelaria, and 150 in Carreto.[23]
An estimated 70 percent of Cartagena saw flooding due to the direct effects of Iota,[25] affecting an estimated 155,000 people.[26] Numerous homes were damaged or destroyed by floods and landslides.[24] City officials converted the Coliseo de Combate into a shelter capable of accommodating 200 people.[27]
On November 15–16, Iota passed close to the outlying Archipelago of San Andrés, Providencia and Santa Catalina. On Providencia, two shelters had their roof blown off and communication was lost with the island around 08:00 UTC on November 16. On San Andrés, numerous trees were uprooted, some of which fell on homes, and several homes lost their roof.[28]
