Here are the seven deadliest hurricanes to hit the U.S. since 2000.

Hurricanes have caused widespread destruction across the United States, especially in the 21st century. From strong winds and heavy rainfall to storm surges and flooding, these natural disasters leave behind a significant impact on communities.

While this is a grim history to look back on, going forward similar disasters are to be expected because of the impeding climate change.

1. Hurricane Katrina (2005)

Hurricane Katrina remains one of the deadliest and costliest hurricanes in U.S. history. This Category 4 storm struck the Gulf Coast in August 2005, resulting in approximately 1,200 deaths.

Most fatalities occurred in Louisiana due to severe flooding in New Orleans. The hurricane also caused $75 billion in damages, mainly due to storm surges and levee failures.

With hurricane seasons becoming more unpredictable, it’s crucial to stay informed and ready. Follow evacuation orders, have an emergency plan, and keep up with weather updates to minimize the potential impact of these natural disasters.

Climate Change and Its Role
