Hurricane Melissa makes landfall on Jamaica, causing chaos | DW News

Key Concepts

• Hurricane Melissa: The most powerful storm in Jamaica's history, making landfall with unprecedented strength.
• Category 5 Hurricane: The highest classification for hurricanes, indicating extreme wind speeds and destructive potential.
• Sustained Wind Speeds: The average wind speed over a period of time, in this case, 175 mph.
• Gusts: Sudden, brief increases in wind speed, exceeding 200 mph for Hurricane Melissa.
• Catastrophic Flooding and Landslides: Predicted consequences of Hurricane Melissa due to heavy rainfall and its slow movement.
• Sea Surface Temperatures (SSTs): Elevated SSTs (above 30°C) are a significant factor in fueling hurricane intensity.
• Climate Change: Identified as a driver of more intense hurricanes, not necessarily more frequent ones, due to increased energy from warmer oceans.
• Mandatory Evacuation: Government-enforced orders for residents in vulnerable areas to seek safety.
• Vulnerable Communities: Areas like Port Royal, historically susceptible to natural disasters.
• Resilience: The capacity of infrastructure and communities to withstand and recover from extreme weather events.

Hurricane Melissa's Impact on Jamaica

Landfall and Initial Observations

Hurricane Melissa, described as the most powerful storm in Jamaica's history, has made landfall. Authorities have issued "shelter in place" orders after earlier mandatory evacuations for thousands of residents. The Red Cross estimates that 1.5 million people, over half of Jamaica's population, could be affected. With sustained winds reaching almost 300 kilometers per hour (approximately 186 mph) and gusts exceeding 200 mph, Melissa is projected to cause catastrophic flooding and landslides as it traverses the island northward. The Jamaican Prime Minister has stated that no existing infrastructure in the region is equipped to withstand a storm of this magnitude.

On-the-Ground Experience in Kingston

Natricia Duncan, Caribbean correspondent for The Guardian, reported from Kingston, the Jamaican capital, describing an "unnerving wait" and escalating "tensions" and "terror" due to rapid, frightening updates. She experienced strong winds and rain overnight, making sleep difficult due to personal safety concerns and the potential compromise of her accommodation. Even before landfall, widespread flooding was observed in some areas, along with downed trees. Hundreds of thousands of people, including Duncan in Kingston, were without power. Her building, however, had a backup generator.

Most Affected Areas and Historical Context

Kingston, while experiencing power outages, has been relatively spared the worst of the storm's impact. The most severely affected areas are anticipated to be places like St. Elizabeth. This region was also devastated by Hurricane Barry the previous summer, with residents still in the process of rebuilding and recovering from the trauma of that event. The recurrence of such a powerful storm so soon after Barry is particularly distressing for these communities.

Reluctance to Evacuate and Government Response

Officials have expressed concern over the reluctance of some residents to seek shelter. Duncan spoke with individuals in Port Royal, a historically vulnerable fishing village that was once a major Caribbean city before an earthquake in the 1600s. Residents there, citing past experiences with hurricanes like Gilbert and Barry, expressed confidence in their ability to cope and a preference to stay put. They also cited negative experiences in shelters, including theft of belongings and safety risks for women. This reluctance led the government to enforce mandatory evacuations to ensure public safety.

Meteorological Analysis of Hurricane Melissa

Unprecedented Strength and Classification

Professor Liz Bentley, President of the European Meteorological Society and Chief Executive of the Royal Meteorological Society, confirmed that Hurricane Melissa is the most powerful storm to make landfall in Jamaica and the most intense of the 2025 hurricane season. It is classified as a Category 5 hurricane, the highest possible. This classification is due to its combination of exceptionally strong sustained winds (175 mph) and gusts exceeding 200 mph, coupled with heavy rainfall.

Impact of Rainfall and Slow Movement

Melissa is a slow-moving system, expected to drop approximately one meter (about 3.3 feet) of rainfall over the next 24 to 36 hours, particularly over higher ground. This rainfall will then flow down into towns and villages, including Kingston, exacerbating flooding risks. The combination of sustained, unprecedented wind speeds and heavy rainfall is the primary driver of the predicted catastrophic impacts.

Role of Sea Surface Temperatures (SSTs)

Elevated sea surface temperatures, exceeding 30°C (86°F), are a significant factor fueling Hurricane Melissa's power. Hurricanes typically require SSTs above 27°C (80.6°F) to develop. The warmer waters provide more heat and energy for these systems. Melissa had been situated south of Jamaica for a couple of days, moving east to west before turning northeast towards the island. During this period over warm ocean waters, it absorbed significant heat and moisture, leading to increased rainfall potential. The storm's slow movement, estimated at only two miles per hour, means that Jamaica will experience prolonged periods of strong winds and heavy rain.

Climate Change and Hurricane Intensity

Professor Bentley emphasized that while climate change may not necessarily lead to more hurricanes, it is contributing to their increased intensity. Warmer sea temperatures, a clear indicator of climate change, provide more energy for these storms. This year alone has seen three Category 5 hurricanes, a stark contrast to the historical average of approximately 45 Category 5 hurricanes over the past 100 years.

Preparedness and Resilience in the Caribbean

While the Caribbean region is accustomed to hurricanes, the intensity of Melissa is a significant concern. Professor Bentley noted that warnings for Hurricane Melissa have been clearer and issued further in advance, allowing for preparation. However, the question of whether the island's infrastructure and communities have become more resilient to such extreme events remains a challenge. Despite improved warnings and mandatory evacuations, the impact on businesses and communities is expected to be substantial. The hope is that the early warnings will minimize the loss of life.

Conclusion

Hurricane Melissa represents an unprecedented meteorological event for Jamaica, characterized by its extreme intensity as a Category 5 storm. The confluence of exceptionally high winds, torrential rainfall, and a slow-moving system, amplified by warm sea surface temperatures linked to climate change, poses a severe threat of catastrophic flooding and landslides. While authorities have improved warning systems and implemented mandatory evacuations, the resilience of infrastructure and the historical reluctance of some residents to evacuate present significant challenges. The event underscores the growing impact of climate change on hurricane intensity, demanding a critical assessment of preparedness and adaptation strategies in vulnerable regions.
