Insurers Expected To Lose Hundreds Of Millions Amid October Extreme Weather: REPORT

Extreme weather taking place throughout the United States mid-October is expected to cause hundreds of millions in losses for insurers, according to Aon who recently released a catastrophe report.

The capacity of the insurance industry has been challenged in several regions due to the storms, adding to problems that already exist in both markets of property and flood insurance. (RELATED: Nearly 50 Vehicles Crash In Major Pile-Up As Black Ice Wreaks Havoc In Finland)

Beginning Oct. 10, the weather systems unleashed strong winds, flooding and damage to infrastructure across the East Coast, West Coast, Southwest and Alaska, per Insurance Business America.

From Oct. 11-14, a nor’easter overwhelmed the East Coast from the Carolinas to New England, while Western Alaska was hammered by remnants from Typhoon Halong, which resulted in damage to houses, businesses and facilities that were available to the public.

With that being said, strength depends on where it goes. Stays south, could develop nicely. Goes north, going to get blasted with wall of shear. pic.twitter.com/5hzD5I8Cuq

Per the report from Aon via Insurance Business America, over 600 properties in Alaska suffered damage, which is joined by the flood and wind losses that were caused widespread in Arizona, New Mexico and Colorado. New York and New Jersey coastal communities also saw damage to property and vehicles due to flooding and uprooted trees.

Extreme weather accumulating is expected to apply pressure to primary carriers and reinsurers in terms of loss ratios, especially as they happen near the end of hurricane season and prior to renewals Jan. 1, per Aon via Insurance Business America.
