A comprehensive, detailed view of severe thunderstorm risk

As severe thunderstorms continue incurring annual industry losses, we continue making scientific and modeling advancements to give you a complete view of risk.

Understand the impacts of all three sub-perils

Identify the frequency, severity, and geographical distribution of the separate tornadoes, hailstorms, and straight-line wind events.

Capture large and small loss-causing events

Get statistical and physical modeling integrated with the latest meteorological research and claims data accounting for all loss-causing events, large or small.

Differentiate vulnerability across regions

Evaluate the implications on loss of different construction materials, occupancy classes, building codes, structure age, and mitigation features.

Verisk’s advanced hail vulnerability module

Look into Verisk’s hail vulnerability module in our updated US Severe Thunderstorm model; it considers the damageability of individual structure characteristics, giving you a better sense of how hail impacts the roof and other parts of a structure.

Insight into highly localized events

Events close in space and time are grouped using clustering algorithms to create realistic individual outbreak patterns of hailstorms and straight-line winds in each location.

Innovative vulnerability frameworks

Our Severe Thunderstorm Risk Models account for regional and temporal variations in sub-peril vulnerability to capture local building practices and characteristics.

Extensive component validation

Each component has been extensively validated against detailed claims data, damage surveys, engineering research, historical events, and industry experience.

Brochure

The Verisk Severe Thunderstorm Model for the United States

Severe thunderstorms are one of the most common and damaging natural catastrophes in the United States. More than half of annual reported industry insured losses, on average, have stemmed from severe thunderstorm events since 1985.

About Catastrophe Modeling

In the case of rare but severe events, historical loss information is often unreliable in assessing future loss potential – that's where catastrophe modeling comes in.
