Build Resilience for an Extremely Active Atlantic Hurricane Season

Build Resilience for an Extremely Active Atlantic Hurricane Season Banner

Record-warm Atlantic Ocean temperatures and a shift to La Niña conditions have led forecasters to predict an extremely active Atlantic hurricane season in 2024. Learn how to build business resilience to mitigate risk for hurricane-prone properties.

Key Takeaways
  1. Persistently rising sea surface temperatures caused by climate change and La Niña , create conditions that are conducive to storm formation as wind shear is reduced.
  2. Predictions for the Atlantic hurricane season include 23 named storms, 11 hurricanes and five major hurricanes.
  3. Ensure a strong business continuity plan is in place prior to the peak of the Atlantic hurricane season, which runs from late August through mid-September.

An expected mid-summer transition from El Niño to La Niña conditions, coupled with a warmer-than-usual tropical Atlantic, have tropical storm forecasters predicting an “extremely active” 2024 Atlantic Ocean hurricane season. Risk managers with occupancies in hurricane-prone areas are therefore encouraged to have a strong business resilience plan in place for an expected intense season.

In April 2024, hurricane researchers at Colorado State University (CSU) made this prediction with “above-normal” confidence.1 National Oceanic and Atmospheric Administration (NOAA) forecasters followed suit in May, predicting an 85 percent chance of an above-normal season.2

Sea surface temperatures in the Atlantic Ocean are anticipated to maintain record-warm levels, creating the thermodynamic engine that enables hurricanes to intensify prior to making landfall. These rising temperatures can be attributed to the effects of climate change, but also El Niño itself, which tends to bring warm ocean waters back to the surface.3

“The transition to a moderate or stronger La Niña is forecast to coincide with the peak of the North Atlantic hurricane season in late August through mid-September,” says Dan Hartung, managing director for Aon’s U.S. Reinsurance Catastrophe Analytics practice. “This could result in reduced wind shear across the main development region of the Atlantic Ocean, which is more favorable for tropical cyclone formation. La Niña also brings a greater chance of a stronger Bermuda High, which could potentially steer storms that do form further to the west, increasing the likelihood of U.S. impacts.”

Florida Cat-Prone Risks Remain in a Difficult Property Market

While overall U.S. property rates continue to soften, and capacity is also more readily available, the Florida property picture is different for risk buyers with hurricane-exposed occupancies:

  • Rates for Florida-only accounts or those accounts with significant Florida natural catastrophe exposures are up 10 percent or more.
  • Capacity also continues to be constrained for Florida windstorm risks. It is adequate, however, for well-engineered and protected risks with limited or no natural catastrophe exposures.
  • Overall, U.S. property rate increases moderated considerably, from 9.6 percent in Q4 2023 to 3.4 percent in Q1 2024. Rate softening is expected to continue into Q2 2024.5

With challenging property conditions continuing for Florida hurricane-prone risks, buyers should consult with an experienced risk advisor early in the renewal process to maximize resilience and risk transfer options, which may include innovative alternative solutions such as parametric insurance.

Parametric is an innovative risk solution that is well-suited for grey swan catastrophic events, including tropical storms. It is designed to complement and supplement a traditional indemnity program and better match capital to the broad nature of risk caused by natural disasters.

The core mechanics of parametric insurance can be defined by three key attributes:

  1. Coverage is triggered by the occurrence of an independent event as determined by neutral third-party data providers, simplifying the underwriting process.
  2. With an independent data trigger and pre-agreed amounts, recoveries occur quickly — as soon as 10 days after an event. This is critical for businesses that need immediate access to capital following an event.
  3. Any economic exposure arising from an event can be insured. As a result, uninsurable exposures become insurable.
Case Study: Deploying Parametric Capacity as a Hurricane Risk Supplement

An energy services firm on the Gulf of Mexico Coast was concerned about the potential impact of a catastrophic hurricane to its facilities. The firm retained a substantial property risk with a $10 million deductible. Its existing insurance covers property damage only, with no coverage for business interruption and additional expense.

Parametric Solution:

  • The client’s traditional insurance program was augmented with a $50 million limit parametric solution triggered by a named storm track coming within 20 to 40 miles of the facility, as determined by the National Hurricane Center.
  • Coverage attaches at a category three strength storm and increases incrementally as its proximity narrows or intensity increases.
  • The parametric solution covers any economic loss of the triggering event.

Prepare Now: 4 Steps to Build a Strong Business Continuity Plan for Hurricanes

Organizations with hurricane-prone exposures must commit to protecting their operations by having clear and actionable plans in place before a hurricane occurs to protect employees, operations, minimize property damage and drive operational resilience.

The overall goal is to allow for an orderly and timely recovery process, with an emphasis on worker safety, as well as a focus on accurate loss documentation. An effective hurricane preparedness and response plan should include critical action steps addressing protective and health safety activities before, during and after a storm.

Businesses or critical suppliers located in hurricane-prone areas should take control of the impending risk by consistently including windstorms in their business continuity plans. This advanced planning and preparation will help mitigate a storm’s impact and assure continuity of crucial business processes. Flexibility and clear, frequent communications will be key in successfully responding to events as they occur.

With an active hurricane season predicted, Aon recommends taking these steps when building and reviewing a hurricane response plan:

  • 1. Identify key stakeholders

    A critical element of a proactive hurricane response plan is to identify and have the contact information for key personnel, external consultants and resources. This includes insurance brokers and adjusters, legal counsel, accounting/finance and restoration contractors, should an event cause damage or render sites temporarily inoperable.

  • 2. Designate a response leader

    It’s important to designate an internal leader, such as the CFO or risk manager, as well as alternate staff to coordinate the response and claims teams to ensure all plan elements are implemented on a timely basis. Creating a flowchart or playbook will help make the entire process more efficient. Plan simulations using various event scenarios can also help address any issues. Consider implementing “call trees” to confirm all team members can be successfully reached during and after an event. These items should also be included or cross-referenced in business continuity plans.

  • 3. Understand business interruption risks

    Include a comprehensive evaluation of the organization’s plants and locations situated in hurricane-prone regions to ensure a full understanding of their risk exposure, business interruption and asset values. There are several mobile applications available that provide business continuity plans to ensure all team members have these details at their fingertips. Further, Aon’s Emergency Response: Hurricane Season Template & Checklist outlines key parts of an enterprise-wide response and recovery process.

  • 4. Address wind, flooding, power outages and loss of communication resources

    Planning should consider more than just wind-related loss. It should also include storm surge, flooding, extended power outages and interruption of land line, cell phone and internet access, as well as site inaccessibility.
