A new view of severe thunderstorm risk—more complete and detailed than ever

As severe convective storms become more frequent and their impacts increase, it’s critical to leverage growing volumes of meteorological and loss data—and expanding scientific research—to build useful, comprehensive thunderstorm risk models for a changing world.

Understand the impacts of all three sub-perils

Identify the frequency, severity, and geographical distribution of 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 to account for all loss-causing events, large or small.

Differentiate regional vulnerabilities

Evaluate the potential loss implications of different construction materials, occupancy classes, building codes, structure ages, 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.

A near-present view of climate risk

The latest available observational and radar data, plus refined historical data interpretations, can help you see current climate patterns and impacts without the reporting bias in hazard data—to support better trend analysis and risk projections.

Comprehensive modeling parameters

Verisk’s model captures convective storm sub-perils such as straight-line winds, hail, and tornadoes with granular frequency, severity, and geographical distribution to help tailor business to these sub-perils by location. Peril-specific damage functions account for unique damage mechanisms imposed by sub-perils to refine loss estimates.

Real-time event monitoring and alerts

Our model can deliver up-to-date information on unfolding perils and provide catalog files for actual events, giving you a more accurate view of current and future convective storm risk.

Solar and specialty risk support

Modeled potential losses span three types of solar utility installations with different components. Refined specialty assessments include industrial facilities, infrastructure, greenhouses, and marine lines.

Extensive component validation

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

The Verisk Severe Thunderstorm Model for the United States

Severe thunderstorms, which can often include significant hail damage and may spawn straight-line winds and tornadoes, are among the most frequent and costly natural catastrophes in the United States, accounting for more than half of annual reported insured property losses since 1985.

About Catastrophe modeling

Historical loss information is often unreliable for assessing future loss potential from rare but severe events. That’s where catastrophe modeling comes in.
