Winter Storms

Winter storms were the third most costly type of natural disaster in the United States in 2011, with $2 billion in insured losses in 2011, according to a report by Munich Re. They were topped by severe thunderstorms (including tornadoes) at $25.8 billion in insured losses and tropical cyclones (including hurricanes) at $5.5 billion in insured losses.

From 1992-2011, winter storms resulted in about $28 billion in insured catastrophe losses (in 2011 dollars), or more than $1 billion a year on average, according to ISO.
