The states with the most weather-related disasters topping more than $1 billion are Texas, Missouri, Alabama, Georgia, Tennessee and South Carolina, which each had at least 31 expensive events in the past 30 years.
When it comes to overall numbers, it's not surprising that the most populous states are home to the most traffic deaths. Texas is great for many things (tasty barbeque, rousing rodeosâ¦), but according to the NHTSA, the Lone Star State had the most fatal car accidents in 2013 with 3,044. California wasn't too far behind with 2,772, and Florida came in third with 2,228.
