Texas has experienced a lot of natural disasters lately, among them a historic deep freeze and an oppressive heatwave, not to mention the tornadoes, cyclones and flash floods that regularly plague parts of the state. Not surprisingly, a new study ranked Texas as the U.S. state third-most affected by costly natural disasters since 1980. That puts it behind hurricane-prone Mississippi and Louisiana, which took the No. 1 and No. 2 spots respectively, according to researchers with finance site Wallet Hub, which compiled the report.
