The total economic damage from Superstorm Sandy could run as high as $50 billion, according to new estimates from the forecasting firm Eqecat. That would make it the second-costliest storm in U.S. history after Hurricane Katrina.
The new numbers Eqecat released Thursday are more than double the firm's previous estimate.
Eqecat said Sandy may have caused between $30 billion and $50 billion in total economic losses, including property damage, lost business and extra living expenses. The cost to insurance companies could run as low as $10 billion and as high as $20 billion.
The firm pointed to two reasons that Sandy will leave a bigger bill than it first thought. Power outages are more widespread than in a typical Category 1 storm, Eqecat said. Sandy knocked out electricity for more homes and businesses than any other storm in history, according to the Department of Energy.
The lack of subway service in New York City and blocked roadways will also push the total cost higher, Eqecat said.
Before the storm hit, Eqecat had estimated that total economic losses from Sandy could range as high as $20 billion and that losses to insurance companies could reach $10 billion. Payouts for insurance claims are typically a fraction of the overall cost to the economy.
If the damages run into the high end of Eqecat's estimates, it would make Sandy the second-costliest U.S. storm after Katrina in 2005. Katrina's overall costs were $108 billion, which would be the equivalent of $128 billion today.
Even after adjusting for inflation, the high end of Eqecat's damage estimates for Sandy would be higher than those caused by previous major storms. Andrew, which struck in 1992, cost $44 billion in today's dollars, and the Ike storm of 2008 cost $32 billion.
Another major firm that calculates the cost of catastrophes, RMS, is gathering information before it makes its first estimate. RMS said Thursday that it has two reconnaissance teams out surveying the damage. The firm has offices in Hoboken, N.J., where floodwaters stranded thousands of people.
