Severe Thunderstorm

Severe thunderstorms are no longer viewed as an attritional risk. Losses, whether from multiple events over the course of a year or a single large event, can be catastrophic. Verisk models help companies better prepare for extreme loss volatility posed by this highly localized peril.

Capture the effects of all three sub-perils.

Understand the frequency, severity, and geographical distribution of the separate tornados, hailstorms, and straight-line wind events that make up a severe thunderstorm outbreak, and employ separate damage functions to isolate their distinct impacts on your portfolio.

Consider large and small loss-causing events.

Verisk’s daily simulation captures the large outbreaks that produce insured losses in excess of USD 25 million and smaller events that may last less than a day, the accumulation of which can have a significant impact on your bottom line.

Differentiate vulnerability across regions and time.

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