Hurricane Katrina was one of the deadliest hurricanes to ever strike the United States and the second Category 5 hurricane of the record-breaking 2005 Atlantic hurricane season.

Storm history[change | change source]

The storm formed over the Bahamas on August 23, where it moved west and hit south Florida as a Category 1 hurricane two days later. Katrina then crossed over Florida and strengthened into a Category 5 hurricane moving west in the Gulf of Mexico.

The storm then turned north, had an eyewall replacement cycle, and hit east Louisiana and Mississippi, flooding coastal areas on the morning of August 29.

The leftovers of Katrina then died out over the Great Lakes on August 31.

Impact[change | change source]

People on the roofs of their houses, to avoid the flood waters

80% of New Orleans was flooded when the levees protecting the city broke.[3][4] Most of the people killed by Katrina were thought to have died from drowning. Many of the survivors had swum to higher roofs or tree branches.
