List of South America tropical cyclones
A South American cyclone is a tropical cyclone that affects the continent of South America or its countries. The continent is rarely affected by tropical cyclones, though most storms to hit the area formed in the North Atlantic Ocean. Typically, strong upper level winds and its proximity to the equator prevents North Atlantic impacts.[1] No tropical cyclone has ever affected the Pacific side of South America, while conditions are typically too hostile for many storms to hit the area from the South Atlantic Ocean. Based on climatology, northern Venezuela and Colombia have a 1 to 5% chance of a hurricane strike in any given year, while all locations south of 10° N have less than a 1% chance of a direct hit.[2] A total of 38 tropical cyclones have affected the continent since 1588.
Storms in the South Atlantic
The South Atlantic Ocean is generally inhospitable to the formation of a tropical storm. Although rare, a growing number of subtropical cyclones have developed in the South Atlantic Ocean near Brazil, such as the unofficially-named Cyclone Catarina of 2004 that made landfall as a Category 2. Since 2011, certain storms have official names, such as Subtropical Storm Arani. At least one storm has formed near the West Coast of Africa.

- August 7–9, 1993 - Tropical Storm Bret moves across northern Venezuela and Colombia. In Venezuela, the storm drops at least 13.35 inches (339 mm) in Guanare. The rainfall causes mudslides, particularly near the city of Caracas, that cover many low-income housing units. Of the 173 deaths caused by Bret in Venezuela, most occur in the low-income areas near Caracas.[24] Lack of preparation, including weather forecasters prematurely stating the worst of the storm is over, is part of the problem.[25] In all, 10,000 are left homeless, and damaged totals $25 million (1993 USD, $37 million 2008 USD). In Colombia, Bret causes one death and one injury.[24]
- July 24–27, 1996 - Hurricane Cesar moves westward across the southern Caribbean Sea and crosses over extreme northern Colombia and the San Andrés archipelago. Cesar kills 11 people in Colombia due to flooding and mudslides.[26]

- September 7–9, 2004 - Hurricane Ivan parallels the north coast of Venezuela as a Category 4 hurricane. Ivan's strong winds forced the closure of several airports. The hurricane also produced heavy rainfall and strong waves.[35] Ivan killed three in the country,[36] though overall damage was minor.[37]
- July 14, 2005 - Hurricane Emily passes just north of Venezuela as a strengthening hurricane, causing heavy rains and flooding in the northeastern portion of the country. 64 families were forced to leave their homes when rivers in eastern Monagas state overflowed their banks, but waters quickly receded. Ships were forced to remain at port while the hurricane passed to the country's north, though restrictions quickly lifted.[38]

The system was eventually classified as a subtropical cyclone, making it the only subtropical cyclone on record to effect South America, and the second subtropical system ever recorded in the South Atlantic, with the first being a subtropical cyclone in 1974. Winds exceeded 54 kts on the coast of Uruguay and extreme southern Rio Grande do Sul, and the system produced 300 mm of rainfall or more in 24 hours in some locations of Rocha (Uruguay) and southern Rio Grande do Sul. Fourteen deaths and thousands of evacuees are attributed to the storm with an emergency declared in four cities.
- March 10, 2010 - Unofficially named (by private and public weather centers from Southern Brazil) Tropical Storm Anita (90Q) affected the coast of southern Brazil. The cyclone develops out of a subtropical cyclone and is one of the rare tropical cyclones developed in South Atlantic Ocean waters.

Deadliest storms
Data from South American tropical cyclones is sparse and incomplete, though most tropical cyclones that struck the continent caused multiple deaths. Bret, Joan, Cesar, Gilbert, Catarina, and Ivan all caused their deaths through rainfall or flash flooding.
Tropical cyclone warnings and watches
In the event an Atlantic hurricane threatens the northern coast of South America, the National Hurricane Center defines nine locations as tropical cyclone warning breakpoints. The westernmost is the border between Panama and Colombia, and the easternmost is Georgetown, Guyana, located at 6.82° N. In the eastern Pacific Ocean, tropical cyclone warning breakpoints extend eastward to the border of Panama and Colombia at 7.23° N.[41] No Atlantic hurricane has existed south of 6.82° N,[42] and no Pacific hurricane has existed east of 80° W,[43] though in the event a tropical cyclone threatens a region of South America without warnings, additional warning sites can be selected. In addition to warnings on the mainland of South America, the National Hurricane Center defines the entire island of San Andres as a tropical cyclone warning breakpoint.[41]
Intense Hurricane Flora in 1963 prompted officials to declare gale warnings for two islands off the north coast of Venezuela.[44] In 1974, the passage of Tropical Storm Alma warranted the issuance of Gale Warnings for the Paria and Paraguaná Peninsulas.[19] Hurricane Joan in 1988, Tropical Storm Bret in 1993, Hurricane Cesar in 1996, and Hurricane Felix in 2007 resulted in tropical storm and hurricane watches and warnings for several locations in South America.[45][46][47][48] The threat of Hurricane Ivan prompted a hurricane watch and a tropical storm warning for the northern coast of Venezuela.[49]
