Galveston County is the highest-risk county in Texas and one of the most hurricane-vulnerable counties in the nation. Galveston Island itself sits barely above sea level, and Hurricane Ike in 2008 caused catastrophic storm surge that inundated the island. The 1900 Galveston Hurricane remains the deadliest natural disaster in US history.
