Caribbean Hurricane Belt is a climatological corridor in the western Atlantic where tropical cyclones frequently pass each year. It encompasses island states, continental coastlines and maritime routes historically affected by storms such as Hurricane Gilbert (1988), Hurricane Jeanne (2004) and Hurricane Irma (2017). The belt shapes regional policy in capitals including Havana, Kingston, Port-au-Prince, Santo Domingo and San Juan.

Geography and boundaries

The belt extends from the western Atlantic Ocean into the greater Caribbean Sea and Gulf of Mexico, bounded north by the Bermuda–Florida corridor and south by the northern coastlines of Venezuela and Colombia. Major island chains inside the belt include the Greater Antilles—Cuba, Hispaniola, Jamaica, Puerto Rico—and the Lesser Antilles such as Barbados and Grenada; continental neighbors include Mexico's Yucatán Peninsula and Belize. Shipping lanes connecting Panama Canal traffic and transatlantic routes cross the belt, while ports like Kingston Harbour, Port of Havana, Port of Spain, Castries Harbour and Freeport, Bahamas lie within high-risk zones. The region intersects exclusive economic zones of states represented in organizations like the Organization of American States and the Caribbean Community.

Climate and meteorology

Tropical cyclone genesis in the belt is influenced by Atlantic sea surface temperatures, the Intertropical Convergence Zone, and large-scale oscillations such as the El Niño–Southern Oscillation, the North Atlantic Oscillation, and the Atlantic Multidecadal Oscillation. Wind shear, mid-tropospheric humidity and Saharan dust outbreaks linked to the Sahara Desert modulate development of storms that later affect islands like Antigua and Barbuda and Saint Kitts and Nevis. Atmospheric features including the Bermuda High steer systems toward coasts like Florida and Yucatán or into the eastern Gulf of Mexico. Studies by institutions such as the National Oceanic and Atmospheric Administration, the European Centre for Medium-Range Weather Forecasts, and the National Hurricane Center analyze cyclone structure using dropsondes from aircraft like those operated by the United States Air Force Reserve Command.

Hurricane season and historical impact

The climatological season from 1 June to 30 November has produced catastrophes including Hurricane Mitch (1998), Hurricane Flora (1963), and Hurricane Matthew (2016). Historical records from colonial archives in Spain and France document early impacts on settlements such as Santiago de Cuba and Santo Domingo, while modern reconstructions use datasets from the International Best Track Archive for Climate Stewardship and the HURDAT2 database. Notable landfalls at major population centers—New Orleans during Hurricane Katrina (2005), Nassau in Hurricane Dorian (2019), and San Juan in Hurricane Maria (2017)—illustrate fatalities, infrastructure collapse, and long-term displacement documented by agencies like the United Nations and the World Bank.

Socioeconomic effects and preparedness

Economic shocks from storms affect tourism hubs such as Punta Cana, Montego Bay, and Aruba; agricultural regions in Cuba and Haiti; and extractive industries in Trinidad and Tobago and Venezuela》]. Recovery costs have been estimated in post-disaster assessments by the Inter-American Development Bank, the International Monetary Fund, and the Caribbean Development Bank. Preparedness policies are coordinated through mechanisms including the Caribbean Disaster Emergency Management Agency, national disaster offices in Belmopan and Bridgetown, and regional contingency planning under the Pan American Health Organization. Insurance markets led by firms headquartered in London and Miami and pooled instruments like the Caribbean Catastrophe Risk Insurance Facility influence resilience financing. Migration responses have involved diasporas in United States, Canada, and United Kingdom cities such as Miami, Toronto, and London.

Ecosystems and environmental consequences

Storms reshape ecosystems from mangroves in Everglades National Park and Sian Ka'an to coral reefs in the Mesoamerican Barrier Reef System and seagrass beds near Tobago Cays. Hurricanes cause freshwater flooding that alters watersheds like the Mopan River and the Artibonite River, and promote coastal erosion at sites such as Negril and Varadero. Biodiversity impacts affect species protected under agreements involving the Convention on Biological Diversity and regional initiatives by the Caribbean Biodiversity Fund; coral bleaching events exacerbated by rising temperatures linked to Anthropocene warming reduce reef calcification and fisheries that sustain communities in Saint Lucia and Grenada.

Monitoring, forecasting, and mitigation strategies

Operational forecasting combines satellite platforms like GOES and Meteosat, radar networks in Cuba and Puerto Rico, and numerical models developed at centers including NOAA's Geophysical Fluid Dynamics Laboratory, ECMWF, and academic groups at University of the West Indies. Early warning dissemination uses radio systems in Haiti, emergency alerts in Dominican Republic, and transnational coordination through the Caribbean Meteorological Organization. Structural mitigation includes building codes in Cayman Islands, coastal setbacks near Barbados tourist zones, and ecosystem-based approaches such as mangrove restoration funded by the Global Environment Facility. Financial instruments—cat bonds issued in New York and regional insurance pools—complement capacity building from programs by the United Nations Development Programme and training by Red Cross and Red Crescent Movement societies.
