Interesting article about more accurate determination of a hurricane’s damage potential.
"Surface pressure is a better benchmark than sustained wind speeds for forecasting hurricane damage potential, according to a new study from Colorado State University ."
This is most significant in coastal areas. A cat 2 hurricane on the Saffir-Simpson scale is expected to produce a coastal storm surge between 6 to 8 feet with a barometric pressure in the 965 to 979 millibar range. When Ike hit Galveston as a cat 2 in 2008 with sustained winds of 110 mph, it had a surface pressure of 950 millibars. There was plenty of wind damage but the 20’ surge is what caused the most catastrophic amount.
Katrina was 902. Maria was 908. So the correlation with pressure makes sense. Both were very destructive storms
And “Superstorm Sandy” was 940 when it hit NJ/NY, even though the winds were down to about 75 knots.
