Understanding the Financial Impact of Hurricane Melissa
BOSTON — The Extreme Event Solutions group at Verisk (Nasdaq: VRSK), a prominent global data analytics and technology provider, recently announced that the industry is looking at insured losses to onshore property in Jamaica due to Hurricane Melissa, with estimates ranging from USD 2.2 billion to USD 4.2 billion. This estimation includes the losses incurred from both wind and flood damage, with the majority attributed to high winds.
Meteorological Journey of Hurricane Melissa
Hurricane Melissa formed on October 21. During its development, it encountered exceptionally warm sea surface temperatures and low wind shear, which led to a rapid intensification phase on October 25. As it turned north-northeast, Melissa strengthened further, producing maximum sustained winds of 185 mph and reaching a minimum central pressure of 892 mb before making landfall near New Hope in Jamaica on October 28.
After making landfall, the storm weakened but remained a Category 4 hurricane as it headed towards Cuba, landing there on October 29. Its subsequent path took it near Long Island in the Bahamas, where it began to speed up.
Assessing the Damage through Building Codes
In Jamaica, around 70 percent of residential buildings are constructed from masonry materials, while the remaining 30 percent are wood-framed. Generally, the roofs tend to be either flat or have low pitches, and construction practices often lack professional oversight. Consequently, when a powerful hurricane like Melissa hits, the damage can be catastrophic—many buildings may face severe structural damage or even total destruction.
In areas such as St. Elizabeth parish, where the hurricane made landfall, reports indicate that damage has substantial consequences, with estimates suggesting 80 to 100 percent of roofs destroyed in some neighborhoods.
Both non-engineered residential structures and engineered commercial buildings endured similar levels of devastation. This encompasses everything from grocery stores and gas stations to hospitals and airports. While wind and rain contributed significantly to the damage, many areas also experienced serious flooding.
Flood Damage and Building Resilience
In Montego Bay, a popular tourist destination, major storm surge, wind, and precipitation-induced flooding were reported, which has affected local resorts. Eastern Jamaica, including the capital, Kingston, also experienced extensive flooding, emphasizing the broad-reaching consequences of Hurricane Melissa.
The importance of building codes comes into sharp focus when assessing the impacts of such severe weather events. Jamaica's primary building code, drafted in the early 1900s, primarily outlined regulations without stringent enforcement. Subsequent developments, including the Caribbean Uniform Building Code (CUBiC) in 1985, offered some guidelines, but they were not always mandatory for construction practices in Jamaica.
The establishment of a National Building Code by the Jamaica Institute of Engineers in 2003 aimed to approach wind engineering more seriously. By detailing basic design wind speed maps for various regions, it helped engineers design appropriate structures. However, when Hurricane Melissa struck, wind speeds in impacted areas surpassed the established design limits, leading to predictable devastation.
Aftermath and Insurance Considerations
The insurance landscape in Jamaica exhibits significant uncertainty, as fewer than 20 percent of residential properties are covered, and many are underinsured. This lack of insurance coverage extends to commercial properties and vehicles, highlighting a crucial gap in the country's preparedness for natural disasters.
Verisk’s loss estimates intentionally exclude various factors from their calculations, including:
- Losses resulting from government programs
- Financial impacts from Melissa’s interactions with other regions
- Modeling of coastal storm surge losses
- Intricacies of marine losses
- Impacts on structures lacking insurance
- Infrastructure damage
- Costs associated with extra-contractual obligations
- Cleanup expenses
- Demand surge effects
Record-Breaking Hurricane
Hurricane Melissa set several significant records, standing out as the most intense hurricane to strike Jamaica since modern records began, marking a pivotal event in the data collected on extreme weather systems. Its minimum central pressure and maximum wind speeds also tie it for some of the most intense storms globally.
