Verisk has introduced a significant enhancement to its United States Tropical Cyclone Model, now available through its cloud-native Synergy Studio platform. The release is intended to give insurers, reinsurers, and capital markets participants a more realistic understanding of both individual property risk and broader portfolio exposure.
The revised model is built around a near-present climate perspective, using recent hurricane activity and loss experience to improve how current risk is measured. Verisk said the upgrade strengthens the representation of hazard behaviour, vulnerability, and the main factors that drive losses from tropical cyclone events.
According to the company, the model brings together an updated stochastic event catalogue, a peer-reviewed hurricane wind-field methodology, and a full reassessment of vulnerability assumptions. This approach is designed to better reflect how hurricanes affect communities today, including coastal storm surge impacts and inland flooding caused by heavy rainfall, while offering a clearer and more transparent view of potential losses.
Verisk also noted that the updated model went through extensive outside review. That process included academic peer review and publication of the revised wind-field methodology, along with independent expert evaluation of the event set and vulnerability modules. The company said this external scrutiny complements its own internal scientific validation and supports the level of discipline needed for risk analysis used in critical public and private decision-making.
The model is being delivered alongside Verisk’s wider catastrophe modelling suite on Verisk Synergy Studio, a platform created to combine catastrophe modelling, exposure management, and risk analytics within one connected environment. Verisk said the system is built to support larger and more complex portfolios through modern workflows, high-performance computing, and open, non-proprietary exposure data formats.
The company added that the platform also incorporates an updated global financial modelling framework, making it easier for organizations to connect modelling outputs with enterprise risk processes. By combining advanced risk science with a modern cloud-based infrastructure, Verisk said Synergy Studio can support more frequent model updates and stronger workflow integration.
Rob Newbold, president of Verisk Catastrophe and Risk Solutions, said the insurance sector is operating in an increasingly complex and interconnected risk environment. He explained that the updated U.S. Tropical Cyclone Model and Synergy Studio are designed to help decision-makers gain a more defensible view of risk while improving how they evaluate exposure, allocate capital, and manage operations in current climate conditions.
Jay Guin, executive vice president and chief research officer at Verisk, said the release reflects years of progress in atmospheric science, hazard modelling, and loss validation. He added that by incorporating a near-present climate view and more advanced treatment of wind, storm surge, and flooding, the model offers a more realistic picture of how hurricanes behave today and how resulting losses may unfold.
The updated model and Verisk Synergy Studio are scheduled to become available on June 15, 2026. Verisk said clients will be supported through a phased migration process, with validation materials and model documentation provided to help with implementation and adoption.
