Wednesday, October 29th, 2008 — A risk assessment group now says damage costs from Hurricane Ike could go as high as $21 billion. That figure would make Hurricane Ike the third most expensive storm in U.S history, behind Hurricanes Katrina and Andrew. The new estimate from Risk Management Solutions of $13 - $21 billion is higher than the $7 - $21 billon figure the group released just four days after the Sept. 13 storm.
