Dear Gadol,
This was the tenth-strongest U.S. hurricane landfall by windspeed on record.
Storm surges are responsible for the bigger disasters.
We have had some really major storms this decade. Many different areas were devastated by hurricanes. Houston is the only (As far as I recall.) area to be hit multiple times.
Harvey does not compare to Katrina.
I think more people are evacuating now than ever before. There has been an added stress on adequate shelter space. And security for vacated towns is much improved.
