Verisk has unveiled a major update to its Tropical Cyclone Model for the United States, delivered through its new cloud-native Synergy Studio platform, providing a more realistic assessment of individual risk and portfolio exposure across insurance, reinsurance, and capital markets.
According to Verisk, the updated U.S. Tropical Cyclone model reflects a near-present climate view, grounded in recent tropical cyclone behaviour and impacts, enhanced hazard and vulnerability modelling, and a clearer representation of loss drivers.
The firm explained that it combines an updated stochastic event catalogue, peer-reviewed wind-field methodology, and a comprehensive reevaluation of vulnerability to better capture how hurricanes behave today and how that translates into losses—such as damage driven by storm surge in coastal areas and rainfall‑driven inland flooding—delivering a more accurate and transparent view of risk.
The updated model is said to have undergone extensive external evaluation, including academic peer review and publication of the new hurricane wind-field methodology, and review and evaluation of the new event set and vulnerability modules by independent experts.
Verisk observed that this process complements internal scientific validation by its domain-area experts and reflects the level of rigour required for risk assessments that inform high-stakes public and private decision‑making.
As mentioned, the updated model, along with Verisk’s global suite of catastrophe models, is delivered on Verisk Synergy Studio, a cloud‑native platform reportedly designed to unify catastrophe modelling, exposure management, and risk analytics in a single environment.
“The platform supports larger, more complex portfolios with modern workflows and high‑performance computing, while leveraging open, non‑proprietary exposure data formats and an updated, globally connected financial modelling framework,” Verisk said.
The firm added that by pairing advanced science with a modern platform, Synergy Studio enables more frequent model updates and improved integration with enterprise risk workflows.
Rob Newbold, president of Verisk Catastrophe and Risk Solutions, commented, “Insurance leaders are navigating a more complex and interconnected risk environment than ever before.
“The updated U.S. Tropical Cyclone model and Verisk Synergy Studio are designed to support those decisions—providing a more defensible view of risk on a modern platform that helps organisations assess exposure, manage capital, and operate with confidence in today’s climate.”
Jay Guin, executive vice president and chief research officer at Verisk, added, “This update reflects years of advances in atmospheric science, hazard modelling, and loss validation. By incorporating a near‑present view of climate conditions and improved representations of wind, storm surge, and flooding, the model provides a more realistic picture of how hurricanes behave and how losses may occur today—not decades ago.”
The updated model and Verisk Synergy Studio will both be available starting June 15, 2026. Verisk said it is supporting clients through a phased migration process, with validation resources and model documentation available to support adoption.
