Verisk is analyzing the multi-faceted impacts from recent catastrophes, including Hurricane Idalia, Canadian and Hawaiian wildfires.

To close this series, we discuss US Severe Thunderstorm risk and the Verisk approach, our validation methodology, and how to use your claims experience with our model to form your own view.

In this article, the second of three in our series on managing U.S. severe thunderstorm risk, we discuss our innovative and first-of-its-kind hail vulnerability framework and how our updated model can distinguish the view of risk from one property to another.

This article discusses newly available data, technological advances, and the importance of capturing all severe thunderstorm outbreaks to successfully manage this risk. In addition, we discuss the impact of climate change on the severe thunderstorm peril

Gain insight into the industry loss potential from all sources of flooding and Verisk’s solutions.

Recently, AIR released a major update to our flagship U.S. hurricane model, along with a substantially updated U.S. inland flood model. Both models incorporate the same new pluvial component that uses a physically based 2-dimensional (2D) shallow water wave model to simulate pluvial flood risk over the entire contiguous U.S. These two models also incorporate the same new precipitation-induced flood vulnerability framework. Together, these two models provide a comprehensive view of U.S. flood risk—from both tropical and non-tropical sources on and off the floodplain as well as from storm surge.

This article focuses primarily on damage surveys conducted in the aftermath of U.S. hurricanes and addresses how and why we conduct them. As we update our U.S. hurricane model—a tool that helps quantify the risk—we uncover more questions that are typically answered only after studying another event.

Verisk's team surveyed areas around Miami and the Florida Keys to understand the nature and intensity of wind and storm surge damage from Hurricane Irma.

Explaining the inner workings of one of the most critical (and difficult to develop) components of a catastrophe model—its damage functions.
