Depending on the severity of the storm and the preparedness of those in its path, hurricanes are capable of causing thousands of deaths. The 1900 Galveston hurricane was a Category 4 storm that resulted in approximately 8,000 fatalities.
In 2005, the massive Hurricane Katrina, which was a Category 5 storm, downgraded to a level 3 storm during the course of its path over the Gulf of Mexico, before hitting land in Louisiana and Mississippi. Katrina still delivered punishing winds and rising waters from storm surges, bringing widespread destruction, flooding and death. Katrina was responsible for approximately 1,836 deaths and caused property damage estimated at $81 billion.
