Winter Storm to Break Insurance Records; Other February Storms

February saw a spate of winter storms in the United States, including the period from Feb. 12-20, which will become the U.S. insurance industry’s costliest winter weather peril on record, according to insurance broker Aon plc in its monthly Global Catastrophe Recap report.

The total direct economic damage cost (and net-loss business interruption) was expected to well exceed $10 billion, Aon said, noting that there will be a prolonged period of loss development.

This stretch of winter weather conditions affected nearly every section of the United States, extending as far south as the U.S.-Mexico border. Caused by a polar vortex, the storms brought millions of power outages, transportation disruptions, extensive property damage (particularly in the Southern Plains due to burst pipes), as well as agricultural sector losses.

The unprecedented volume of winter weather impacts tied to the polar vortex across the United States in mid-February will result in a prolonged period of loss development, but will certainly end as the costliest insurance industry event for the peril on record, commented Steve Bowen, director and meteorologist on the Impact Forecasting team at Aon.

“Despite being the coldest February for the contiguous U.S. in a generation, it marked only the 19th coldest February dating to the late 1800s,” he said. “As the climate changes, such prolonged bouts of cold temperatures are likely to be less frequent, but the intensity of extreme cold events will grow more volatile. The impacts in Texas highlight the importance of infrastructure modernization and improved building code practices to better prepare for more unusual weather behavior in the future.”

Other notable U.S. winter storms included an Arctic outbreak, which settled across portions of the central United States on Feb. 8-12, causing economic losses in the tens of millions of dollars. Some of the hardest-hit areas were Arkansas, Kentucky, Tennessee and Texas.

Meanwhile, another significant loss during the month included thunderstorms and large hail, which hit portions of northern Texas on Feb. 25-26. Ping pong-ball sized hail was reported in the densely populated Dallas suburb of McKinney in Collin County.

Total economic damage was expected to exceed $100 million, most of which will be covered by insurance.
