A South American hurricane 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 are formed in the North Atlantic Ocean. Typically, strong upper-level winds and its proximity to the equator prevents North Atlantic impacts. [1] Cyclone Yaku is the only known tropical cyclone to have ever affected the Pacific side of South America on record, albeit its status as a tropical cyclone is unofficial.[ citation needed ] Although conditions are typically too hostile for many storms to hit the area from the South Atlantic Ocean, there have been a few tropical cyclones to affect land. 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]
44 tropical cyclones have affected South America in most months of the year.

Data from South American tropical cyclones is sparse and incomplete, though most tropical cyclones that struck the continent caused multiple deaths. Bret, Julia, Joan, and Cesar all caused their deaths through rainfall or flash flooding.

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. [74] No Atlantic hurricane has existed south of 6.82° N, [75] and no Pacific hurricane has existed east of 80° W, [76] 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. [74]
Intense Hurricane Flora in 1963 prompted officials to declare gale warnings for two islands off the north coast of Venezuela. [77] In 1974, the passage of Tropical Storm Alma warranted the issuance of Gale Warnings for the Paria and Paraguaná Peninsulas. [21] 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. [78] [79] [80] [81] The threat of Hurricane Ivan prompted a hurricane watch and a tropical storm warning for the northern coast of Venezuela. [82]
The 2003 Atlantic hurricane season was a very active season with tropical cyclogenesis occurring before and after the official bounds of the season—the first such occurrence since the 1970 season. The season produced 21 tropical cyclones, of which 16 developed into named storms; seven of those attained hurricane status, of which three reached major hurricane status. The strongest hurricane of the season was Hurricane Isabel, which reached Category 5 status on the Saffir–Simpson hurricane scale northeast of the Lesser Antilles; Isabel later struck North Carolina as a Category 2 hurricane, causing $3.6 billion in damage and a total of 51 deaths across the Mid-Atlantic region of the United States.
The 1968 Atlantic hurricane season was a below average hurricane season during which only nine nameable storms developed. The season officially began on June 1 and lasted until November 30, dates which conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. Of the named storms, five strengthened into hurricanes; none however intensified into a major hurricane. Only four other seasons since the start of the satellite era—1972, 1986, 1994, and 2013—did not feature a major hurricane. The first system, Hurricane Abby, developed in the northwestern Caribbean on June 1. Abby moved northward and struck Cuba, bringing heavy rainfall and flooding to western portions of the island. Making landfall in Florida on June 4, Abby caused flooding and spawned four tornadoes, but left behind little damage. Overall, the hurricane resulted in six deaths and about $450,000 (1968 USD) in damage. In late June, Tropical Storm Candy brought minor flooding and spawned several tornadoes across portions of the Southern United States. Overall damage from the cyclone reached approximately $2.7 million. 1968 featured two simultaneously active tropical storms during the month of June, a phenomenon that would not occur again until 2023.
The 1981 Atlantic hurricane season featured direct or indirect impacts from nearly all of its 12 tropical or subtropical storms. Overall, the season was fairly active, with 22 tropical depressions, 12 of which became named storms. 7 of those reached hurricane status and a further 3 intensified into major hurricanes. The season officially began on June 1, 1981, and lasted until November 30, 1981. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, tropical cyclogenesis can occur before these dates, as demonstrated with the development of two tropical depressions in April and Tropical Storm Arlene in May. At least one tropical cyclone formed in each month between April and November, with the final system, Subtropical Storm Three, becoming extratropical on November 17, 1981.
The 1933 Atlantic hurricane season is the most active Atlantic hurricane season on record in terms of accumulated Cyclone Energy (ACE), with a total of 259. It also set a record for nameable tropical storms in a single season, 20, which stood until 2005, when there were 28 storms. The season ran for six months of 1933, with tropical cyclone development occurring as early as May and as late as November. A system was active for all but 13 days from June 28 to October 7.
Tropical Storm Odette was a rare off-season tropical cyclone that hit the island of Hispaniola in early December 2003. As the fifteenth named storm of the 2003 Atlantic hurricane season, Odette formed near the coast of Panama a few days after the official end of the Atlantic hurricane season ended on November 30, and ultimately made landfall on the Dominican Republic as a moderate tropical storm, before becoming extratropical on December 7, dissipating two days later.
Tropical Storm Bret was the deadliest natural disaster in Venezuela since the 1967 Caracas earthquake. The third tropical cyclone of the 1993 Atlantic hurricane season, Bret formed on August 4 from a westward-moving, African tropical wave. Bret would later peak as a 60 mph (97 km/h) tropical storm as it neared Trinidad. It took an extremely southerly course through the Caribbean, passing over the coasts of Venezuela and Colombia. High terrain in the northern parts of those countries severely disrupted the circulation of the storm, and Bret had weakened to a tropical depression before emerging over the extreme southwestern Caribbean Sea. There, it restrengthened to a tropical storm and made landfall in Nicaragua on August 10, dissipating soon after. Bret's remnants reached the Pacific Ocean, where they would later regenerate into Hurricane Greg.
Hurricane Charley was the second hurricane to threaten the East Coast of the United States within a year's timeframe, after Hurricane Gloria of 1985. The third tropical storm and second hurricane of the season, Charley formed as a subtropical low on August 13 along the Florida panhandle. After moving off the coast of South Carolina, the system transitioned into a tropical cyclone and intensified into a tropical storm on August 15. Charley later attained hurricane status before moving across eastern North Carolina. It gradually weakened over the north Atlantic Ocean before transitioning into an extratropical cyclone on August 20. Charley's remnants remained identifiable for over a week, until after crossing Ireland and Great Britain they dissipated on August 30.
Hurricane Claudette was a moderately strong tropical cyclone that struck South Texas in July 2003. A fairly long-lived July Atlantic hurricane, Claudette was the fourth depression, third tropical storm and first hurricane of the 2003 Atlantic hurricane season. Claudette began as a tropical wave in the eastern Caribbean. It moved quickly westward, brushing past the Yucatán Peninsula before moving northwestward through the Gulf of Mexico. Claudette remained a tropical storm until just before making landfall in Port O'Connor, Texas, when it quickly strengthened to a strong Category 1 hurricane on the Saffir-Simpson Hurricane Scale. Forecasting of its path and intensity was uncertain throughout its lifetime, resulting in widespread and often unnecessary preparations along its path.
Hurricane Gabrielle was a North Atlantic hurricane that caused flooding in both Florida and Newfoundland in September 2001. It developed in the Gulf of Mexico on the same day as the September 11 attacks; after the attacks, flights were canceled nationwide for two days, and when Gabrielle struck Florida on September 14, it caused a day of additional cancellations. The storm moved ashore with winds of 70 mph (110 km/h) near Venice, a city located south of the Tampa Bay area. The combination of the winds and heavy rainfall, which peaked at 15.1 in (380 mm) in Parrish, left 570,000 customers without power along the west coast and 126,000 customers without power on the east coast. The storm caused about $230 million (2001 USD) in damage in Florida. In the Gulf of Mexico, high waves contributed to two deaths, one of which was indirect; there was also a death due to flooding in Winter Haven.
Hurricane Kyle was the fifth-longest-lived Atlantic tropical or subtropical cyclone on record. The eleventh named storm and third hurricane of the 2002 Atlantic hurricane season, Kyle developed as a subtropical cyclone on September 20 to the east-southeast of Bermuda. Looping westward, it transitioned into a tropical cyclone and became a hurricane on September 25. For the next two weeks, Kyle tracked generally westward, oscillating in strength several times because of fluctuations in environmental conditions. On October 11, the cyclone turned northeastward and made landfalls near Charleston, South Carolina, and Long Beach, North Carolina, at tropical storm status. After lasting as a cyclone for 22 days, Kyle dissipated on October 12 as it was absorbed by an approaching cold front.
Hurricane Karen was a hurricane of non-tropical origin that formed in October of the 2001 Atlantic hurricane season. It developed out of the interaction between a cold front and an upper level trough on October 10 located to the south of Bermuda, and quickly strengthened as an extratropical storm. The storm passed near Bermuda on October 12, producing hurricane-force winds on the island. It then organized, becoming a subtropical cyclone on October 12 and a tropical cyclone on October 13. Karen strengthened to reach 80 mph (130 km/h) winds as a Category 1 hurricane on the Saffir-Simpson Hurricane Scale, and after weakening over cooler waters, it made landfall on Nova Scotia as a tropical storm. It quickly became extratropical.
Tropical Storm Bret was a strong tropical storm that made a rare landfall on the Delmarva Peninsula in June 1981. The sixth tropical cyclone, third designated tropical depression, and second named storm of the season, Bret developed as a subtropical storm from a large area of frontal clouds near Bermuda on June 29. Moving westward, the subtropical storm intensified while producing deep convection, and was consequently reclassified as a tropical storm early on June 30. Around that time, Bret peaked with sustained winds of 70 mph (110 km/h). The storm then began weakening and struck near Oyster, Virginia as a minimal tropical storm early on July 1. Upon moving inland, Bret weakened to a tropical depression and subsequently accelerated prior to dissipating over northern Virginia that same day.
Tropical Storm Alma, the first named storm to develop in the 1974 Atlantic hurricane season, was a short lived tropical cyclone that made a rare Venezuelan landfall. The storm formed from the Intertropical Convergence Zone (ITCZ) on August 12 well to the east of the Windward Islands, but advisories were not issued until the next day when Alma was at peak intensity. Alma entered the southeastern Caribbean Sea at an unusually brisk westward pace of between 20 mph (32 km/h) to 25 mph (40 km/h), prompting numerous watches and gale warnings throughout the nations in this region. After crossing Trinidad, Alma became one of only four tropical storms to traverse the Paria Peninsula of northeastern Venezuela. The storm dissipated on August 15 over the high terrain of Venezuela.
The 1933 Trinidad hurricane was a deadly and destructive tropical cyclone, one of only three Atlantic hurricanes on record to produce hurricane-force winds in Venezuela. The second tropical storm and first hurricane of the extremely active 1933 Atlantic hurricane season, the system formed on June 24 to the east of the Lesser Antilles, unusually early for the Main Development Region (MDR) so early in the calendar year. It moved westward and attained hurricane status before striking Trinidad on June 27. The storm caused heavy damage on the island, estimated at $3 million. The strong winds downed trees and destroyed hundreds of houses, leaving about 1,000 people homeless. Later, the hurricane crossed the northeastern portion of Venezuela, where power outages and damaged houses were reported.
Tropical Storm Bret was the earliest named storm in the calendar year to develop in the Main Development Region of the Atlantic basin on record. The second tropical cyclone of the 2017 Atlantic hurricane season, Bret formed from a tropical wave that had exited off the coast of West Africa on June 12. The disturbance moved swiftly across the Atlantic for several days, steadily organizing despite its low latitude. On June 18, the organization increased enough for the National Hurricane Center (NHC) to begin issuing warnings disturbance while it was located southeast of the Windward Islands. The system continued to organize, and by the next day, it had developed into a tropical storm, the second of the 2017 Atlantic hurricane season. Bret continued moving swiftly to the west and struck Trinidad and Tobago early on June 20, before entering the Caribbean Sea, dissipating shortly afterwards.
Tropical Storm Alberto was a destructive pre-season tropical cyclone which caused $125 million in damage in the Gulf Coast of the United States in May 2018, the costliest for any pre-season tropical cyclone. The first storm of the 2018 Atlantic hurricane season, Alberto developed on May 25 near the Yucatán Peninsula as a subtropical cyclone. As it entered the Gulf of Mexico, Alberto intensified and transitioned into a tropical cyclone. Early on May 28, Alberto reached its peak intensity, with maximum sustained winds of 65 mph (100 km/h) and a minimum pressure of 990 mbar. Afterward, however, dry air caused Alberto to weaken before it made landfall near Laguna Beach, Florida, with winds of 45 mph (75 km/h). Alberto maintained a compact area of thunderstorms as it progressed through the central United States, entering southern Michigan as a tropical depression on May 31. That day, Alberto weakened further and dissipated over Ontario.
During 1993, tropical cyclones formed within seven different bodies of water called basins. To date, 110 tropical cyclones formed, of which 78 were given names by various weather agencies. Only one Category 5 tropical cyclone was formed in 1993. The accumulated cyclone energy (ACE) index for the 1993, as calculated by Colorado State University was 710.4 units.
Tropical Storm Bret was a strong tropical storm that brought gusty conditions and impacts to the Windward Islands and parts of Northern South America. The second named storm of the very active 2023 Atlantic hurricane season, Bret developed from a tropical wave that moved away from the coast of West Africa and formed east of Barbados on June 19. Slow development occurred and the system intensified into a tropical storm. Bret continued to drift west and passed directly over Saint Vincent as it continued to move into the Caribbean. As it entered the Windward Islands, hurricane hunters found that Bret had sustained winds of 70 mph (110 km/h) and a central pressure of 996 mbar (29.4 inHg). For the remainder of the day on June 23, Bret left the islands and passed north of Aruba on June 24. As the storm passed Aruba, it began to weaken; it opened into a trough near Colombia, marking its dissipation.
