Hurricane Melissa’s Aftermath: Unprecedented Impact, Evolving Threats

Hurricane Melissa, a Category 5 storm, devastated Jamaica in late October 2025, causing historic damage, 45 deaths, and displacing thousands. With widespread infrastructure failures—hospitals, schools, utilities—the storm severely disrupted western parishes and tourist hubs. Recovery continues amid elevated security and health risks. International SOS supported pre-storm alerts, crisis coordination, and post-impact traveler and organizational assistance.

Although no hurricanes during the 2025 Atlantic season struck the mainland United States, several impacts occurred in the Caribbean. The largest was Hurricane Melissa, which formed from a tropical wave in mid-October 2025 and quickly intensified into a tropical storm.

Passing over extremely warm water, it had intensified into a major hurricane by the end of the month, contributing to its catastrophic strength and destructive capacity. The storm made landfall on Jamaica’s southern coast as a Category 5 – the strongest on the scale with sustained winds of 185 mph – and traveled northwest across the island.

The storm hit near New Hope, Westmoreland Parish, with 185-mph sustained winds and a central pressure of 892 mb, placing it among the most powerful events in Atlantic history. The storm caused significant damage, with the World Bank and Inter-American Development Bank estimating the physical damage at US$8.8 billion, including large-scale destruction of homes and infrastructure (water, fuel, and electricity), especially on the northwest coast. Tourist infrastructure was particularly affected, resulting in multiple properties closing after sustaining damage, and some remain closed in 2026.

Hurricane Melissa: Jamaica’s Island-Wide Damage and Humanitarian Impact

Melissa brought 15 to 30 inches of rainfall, widespread storm surges of 9 to 13 feet, and devastating winds across Jamaica. These caused massive flooding, landslides, and the collapse of essential infrastructure.

Early assessments reported 45 fatalities and more than 626,000 people affected, with tens of thousands displaced. Roughly 120,000 buildings lost their roofs, including homes, schools, and public facilities, leading to one of the largest mass disruption events in the country’s history, with aftereffects expected to continue well into 2026.

The storm also caused extensive damage to Jamaica’s healthcare network. Black River Hospital was destroyed, forcing the evacuation of 92 patients, while many other hospitals across western Jamaica sustained severe structural damage. More than 450 schools—nearly two-thirds of the national total—reported damage ranging from lost roofs to structural collapse. As power, water, and communication networks failed, over 70-percent of the island temporarily lost electricity.

Emergency Security Actions and Public Health Risks After Landfall

Immediately after landfall, Jamaica’s government declared a national disaster and activated the Office of Disaster Preparedness and Emergency Management (ODPEM) coordination system. Infrastructure failures created widespread safety risks, including blocked access routes, damaged hospitals, contaminated water sources, and prolonged isolation of rural communities.

Authorities introduced curfews, particularly in the Westmoreland Police Division, and restricted movement in order to support emergency services and deter crime during outages. The Jamaica Defense Force and Jamaica Constabulary Force increased deployments to assist evacuations, secure damaged facilities, and protect relief operations.

Flooding and stagnant water led to outbreaks of leptospirosis and heightened risk of mosquito-borne diseases. Water systems remained offline across multiple parishes, leaving communities dependent on emergency purification supplies and on water deliveries. Meanwhile, damaged hospitals—especially in western Jamaica—struggled with limited capacity, requiring support from field hospitals.

More than 500 emergency shelters housed roughly 13,000 people in the initial weeks, while tens of thousands more relocated to friends’ and relatives’ homes or remained in damaged structures awaiting assistance. Many remain displaced as rebuilding efforts continue.

International SOS Crisis Support, Traveler Guidance, and Assistance

As the storm approached, International SOS issued alerts and advice and established a crisis management team at the Americas Assistance Center. In the wake of the event, security was a challenge, with reports of chaos and looting, and limited access to properties for damage assessment.

Travel in and out of the western portion of the country, including the leisure hub of Montego Bay, was difficult and limited due to flooding, damaged road systems, and limited access to necessities. Prior to the storm, International SOS sent out medical and security information and actionable advice for travelers to either evacuate via a commercial carrier, if possible, or shelter in place with enough food, water, and supplies to ride out the storm and its aftermath. In the wake of the storm, International SOS also fielded requests for health and security information, on-the-ground security presence, and risk management advice for the safe deployment of property loss teams to evaluate assets on the island.

Current 2026 Security Conditions and Health Risks Across Jamaica

Jamaica is open to business and visitors, and major infrastructure has largely resumed operations; however, security risks remain high due to both long-standing crime patterns and uneven post-hurricane recovery. On May 28, International SOS will host a free webinar that looks ahead to this year’s hurricane season, featuring best practices for medical security and operational planning. You can register here.

Jamaica remains rated Level 2: Exercise Increased Caution by the U.S. Department of State due to continuing risks associated with violent crime, limited police response capacity, and ongoing post-storm infrastructure issues. Violent crime— including armed robbery, gang-related violence, and homicide—remains elevated, especially in areas of Kingston, Montego Bay, St. Catherine, Spanish Town, and May Pen. Tourist zones experience relatively lower crime rates, though incidents such as armed robbery and sexual assault still occur.

Police maintain frequent checkpoints, particularly along main tourist corridors like the A1 North Coast Highway and T3 Highway 2000 toll road, aimed at curbing firearm-related violence. Travelers may be stopped, searched, or questioned, and should always carry identification.

Some western parishes—especially Black River and parts of Montego Bay—remain in varying stages of recovery, including intermittent utility disruptions and slower emergency response capacity. Visitors are urged to verify service availability and exercise heightened caution when traveling through or near heavily impacted zones.

Hospitals in western regions continue to face limited capacity due to prior storm damage, impacting emergency response times and access to specialized care. Standing water in certain areas still poses risks of water-borne and mosquito-borne diseases, particularly where debris clearance is ongoing.

Ongoing Safety Guidance and Long-Term Recovery Considerations for Jamaica

Hurricane Melissa reshaped Jamaica’s safety and security landscape, creating long-term challenges in infrastructure, public health, and social stability. Though the nation has made significant progress in repairing critical systems and restoring normalcy, security risks remain elevated, particularly in high-crime urban zones and hurricane-affected western parishes.

Ongoing coordination between Jamaican authorities, international agencies, and humanitarian partners continues to stabilize the country. Travelers, organizations, and businesses should maintain enhanced situational awareness, monitor government and International SOS advisories, and verify local conditions as recovery efforts continue through this year.
