Two storms, Hurricane Ida and Hurricane Katrina, came on the same day in eastern Louisiana, 16 years apart in terms of the last 16 hurricanes.

Scientists observe the landscape closely to see how it has developed over time and if there have been any changes that are permanent.

Ida and Laura describe the 1856 Last Island hurricane as the most powerful ever to hit land in Louisiana.

The Category 4 storm hit Louisiana hard, striking the state with torrential rain, strong winds and flooding.

Michael is the most powerful hurricane on record to make landfall in the Florida Panhandle, and the third strongest to make landfall since records began in the country as a whole.

Ida altered the shape of the landscape, although how long that change can be extended is not known.

Climate Central demonstrates that the tropical Atlantic has warm up around 2s during the last century and this, for sure, has made a difference.

Coasts, lakes, rivers and swamps were barely visible from Jefferson, Lafourche, and Plaquemines borough counties.
