Aon: Recent North American SCS and flooding losses to total hundreds of millions of dollars

By Rebecca Delaney

June 6 - (The Insurer) - Continued activity during the severe convective storm (SCS) season across the U.S. has seen another week of severe weather and heavy rainfall, with Aon pegging total insured losses over the past seven days in the hundreds of millions of U.S. dollars.

Scattered severe weather occurred over the south-central, southeast and mid-Atlantic regions of the U.S. between May 29 and 30, with hailstorms in Texas and strong winds in Georgia and South Carolina.

From June 1 to 4, the central U.S. saw more substantial severe weather and flash flooding, with northern Texas and south-central Kansas the worst impacted, particularly around the Wichita and Dallas-Fort Worth metro areas.

Wichita issued a rare flash flood emergency warning, with the Walnut River West Branch exceeding its major river flood stage threshold. Dallas County also issued a flash flood warning on June 3, although Aon noted that large hailstones caused more significant impacts.

Aon added that more severe weather is expected on Friday and over the next few days, with further updates provided in the next weekly cat report.

This marks the latest severe weather in an active SCS season across the U.S. Last week, Aon estimated that insured losses from SCS activity in the prior seven days were expected to run into billions of U.S. dollars.

Aon also said insured losses from SCS activity across several U.S. states from May 14 to 20 are expected to total billions of U.S. dollars, with a tornado in St Louis alone generating $1.6 billion.

An event update issued by the broker on May 22 pegged total economic and insured losses from hail and wind damage sustained over the central and eastern U.S. from May 14 to 17 as "well into the single-digit billions" of U.S. dollars.
