What kills people in Tropical Cyclones like Hurricane Ian category 4

Surge 49%

Flooding 27%

Wind  8%

Surf 6%

Offshore 6% 

Tornado 3%

So, the surge we are now seeing is likely to kill the most people during these next couple of days across Florida. And ocean Flooding and Rain river Flooding will likely be the 2nd biggest killer of people in Florida.

Hurricane Katrina in 2004.
