Confidently Manage Peak Peril Risk

The average annual insured loss from severe convective storms in the United States is $17 billion, over $1 billion higher than the average annual loss from hurricane winds. And they are regularly the most expensive peril in Canada.

Beyond Historical Data

Fill the gaps and biases associated with incomplete historical data while maintaining proper severity of losses with an advanced hybrid model.

Flexible Sub-Peril Modeling

Examine hail, tornado, and straight-line wind separately or together in any desired combination to understand cause of loss.

Catastrophic vs Non-Catastrophic

View all potential sources of loss across the full spectrum of cat and non-cat events with the freedom to isolate or combine them.

Complete View of Risk

Take advantage of a complete view of hazard, vulnerability, and loss to enable accurate risk management of severe weather.

Unified Event Set

One event set covers both the contiguous U.S. and Canada, ensuring that the hazard correlation between these two countries is preserved.

Comprehensive Vulnerability Modeling

The models contain an extensive suite of peril-specific vulnerability curves and regions: 800 unique vulnerability curves across 11 vulnerability regions. 

Lightning Included

Lightning damage to exterior elements as well as to contents is included in the models for complete coverage of all Severe Convective Storm sub-perils.

May Tornadoes Leave U.S. in a Whirlwind

Late May 2019 was a startlingly active period for severe convective storms (SCS) in the U.S., even after considering that May is typically one of the most active months of the year. Until about halfway through the month, the number of tornadoes being reported was around average, but after a major outbreak starting in mid-May this number shot up, bringing the year-to-date total to 1,017 tornado reports. This count is only surpassed by the extremely active years…
