Insured losses from winter storms in the US this year are tipped to exceed $US2.5 billion ($2.9 billion), as parts of the country again shiver under an Arctic blast.

The Insurance Information Institute says Munich Re data indicates $US2.4 billion ($2.8 billion) of insured losses were incurred in storms from January to March.

“Losses from snow, ice, freezing and related causes averaged $US1.2 billion ($1.4 billion) annually over the past 20 years,” institute President Robert Hartwig said.

“This year insured losses from severe winter events will be at least double that amount, likely exceeding $US2.5 billion by year’s end.”

It would make this year the fourth-costliest for winter storms.
