Total insured and uninsured losses from severe convective storms that struck several U.S. states last weekend will be about $3 billion, catastrophe modeling company Karen Clark & Co. estimated.

The estimate includes losses to privately insured damage to residential, commercial and industrial properties.

Severe storms and a tornado outbreak impacted Arkansas, Illinois, Kentucky, Mississippi, Missouri and Tennessee during the overnight hours of Dec. 10 and Dec. 11.

KCC said what is being called the Quad-State Tornado caused immense damage across four U.S. states. The most significant damage was observed in Kentucky, particularly in Warren and Graves counties, where hundreds of homes and businesses were destroyed.
