Hurricane Matthew

Hurricane Matthew was a powerful and long-lived Atlantic tropical cyclone that caused catastrophic impacts across the Caribbean and the southeastern United States in late 2016. Originating from a tropical wave off the western coast of Africa, Matthew intensified into a major hurricane that produced extreme winds, storm surge, and inland flooding, with the heaviest damage in Haiti, Cuba, Bahamas, and the state of Florida. The storm influenced regional emergency response, international aid efforts, and discussions about tropical cyclone forecasting and resilience.

Meteorological history

Matthew developed from a tropical wave that emerged from the west coast of Africa and transited the eastern Atlantic, interacting with the Intertropical Convergence Zone and warm Atlantic Ocean sea surface temperatures. The system organized into a tropical depression and strengthened to a tropical storm while approaching the Lesser Antilles, then underwent rapid intensification in the central Caribbean, reaching Category 5 intensity with maximum sustained winds near 165 mph and a minimum central pressure near 934 mbar. Steering currents associated with the Azores High and a mid‑latitude trough directed Matthew northwestward toward Hispaniola and Cuba, where interaction with terrain caused temporary weakening before re‑strengthening over the warm waters of the Straits of Florida. Matthew then tracked parallel to the eastern coast of Florida and the coasts of Georgia and South Carolina as a major hurricane before recurving northeast and transitioning to an extratropical cyclone over the western Atlantic.

Preparations and warnings

National meteorological and disaster agencies issued phased warnings as Matthew evolved, including hurricane warnings and tropical storm warnings for the Lesser Antilles, Hispaniola, Cuba, the Bahamas, and the southeastern United States. In Haiti, the civil protection agency coordinated evacuations and international organizations like United Nations agencies and International Red Cross and Red Crescent Movement mobilized pre‑positioned relief supplies. Cuban authorities enacted well‑known mass evacuation plans, mobilizing the Instituto de Meteorología de Cuba and provincial governments to shelter residents. In the United States, state governors in Florida, Georgia, and South Carolina declared states of emergency and coordinated with the Federal Emergency Management Agency and United States Coast Guard to prepare for potential evacuations, search and rescue, and infrastructure protection.

Impact by region

Caribbean: Matthew caused widespread devastation in parts of the Caribbean. In Haiti, catastrophic flooding and mudslides from intense rainfall destroyed homes and crops, contributing to a high mortality toll and exacerbating food insecurity addressed by World Food Programme operations. In Cuba, coastal surge and wind damage affected tourism infrastructure in eastern provinces, prompting emergency response by Cuban Revolutionary Armed Forces. The Dominican Republic experienced flooding and displacement, while sectors in the Bahamas—notably on Grand Bahamas and Abaco—suffered extensive coastal damage.

United States: Along the US Atlantic seaboard, Matthew produced life‑threatening storm surge, coastal erosion, and flooding. Florida saw widespread power outages, coastal inundation in Brevard and St. Johns counties, and impacts to the space infrastructure at facilities near Cape Canaveral. Georgia and South Carolina contended with downed power lines, wind damage, and inland flooding; North Carolina experienced heavy rainfall and riverine flooding as the system moved offshore and its remnants interacted with frontal boundaries.

Economic and human toll: The storm inflicted billions in insured and uninsured losses across affected countries, disrupted agriculture and tourism, and required large scale humanitarian assistance by international organizations such as United Nations Office for the Coordination of Humanitarian Affairs and non‑governmental organizations like Médecins Sans Frontières.

Aftermath and recovery

International aid flows and national recovery plans focused on shelter, water and sanitation, medical care, and rebuilding critical infrastructure. In Haiti, humanitarian response confronted logistical challenges, cholera concerns, and reconstruction needs, with assistance from bilateral donors and multilateral institutions including the World Bank and Inter‑American Development Bank. Cuba implemented rapid reconstruction strategies using centralized coordination by the Council of State of Cuba and provincial entities to repair housing and utilities. In the United States, federal emergency declarations enabled funding and technical support from FEMA for debris removal, temporary housing, and public infrastructure repair, while insurance claims were processed through private insurers and the National Flood Insurance Program.

Longer‑term recovery efforts included resilient rebuilding of coastal protection, retrofitting of electrical grids, and agricultural rehabilitation supported by development agencies and scientific partners such as the National Oceanic and Atmospheric Administration and the United States Geological Survey.

Records and climatology

Matthew became the first Category 5 Atlantic hurricane since Felix (2007) to reach that intensity in the Caribbean basin and set records for sustained intensity during its transit of the Caribbean. Its rapid intensification highlighted forecasting challenges tied to ocean heat content and upper‑level atmospheric conditions studied by teams at NOAA and academic institutions including Columbia University and Florida State University. The storm's impacts contributed to analyses of trends in Atlantic hurricane activity, sea surface temperature anomalies, and links investigated by researchers at the National Academies of Sciences, Engineering, and Medicine and climate centers like the International Research Institute for Climate and Society.
