The Insurance Council of Texas has estimated about $2 billion in insured losses as a result of Sunday’s nine tornadoes across North Texas.

That would mean the tornadoes are the costliest severe weather event in North Texas’ history, said Camille Garcia, a spokeswoman for the Insurance Council of Texas.

For comparison, the tornadoes that devastated Rowlett and Garland in 2015, killing several people, clocked in at $1.2 billion in insured losses.

Last weekend’s storms caused widespread damage, particularly when the strongest of the nine tornadoes cut a path from northwest Dallas to Richardson, reaching wind speeds of up to 140 mph, according to the National Weather Service.

In addition to leveling homes across the area, the storms caused “a host of commercial property damage,” which is one of the reasons why these storms are estimated to be more expensive than the 2015 tornadoes, Garcia said.

She called the $2 billion number, which is for damage wrought by all nine twisters, a “pretty conservative estimate.”
