The strongest hurricanes to hit the US mainland and other tropical cyclone records

Here's a look at the most powerful storms to hit the US mainland.

September 26, 2024, 8:49 AM

Few weather events can cause as much damage and destruction as hurricanes. From Andrew to Katrina, the memories remain of communities devastated by the tropical systems.

But which storm is the worst in U.S. history?

There are a few ways to rate the severity of a storm when trying to define the "worst" or "biggest" -- wind speed, lowest internal pressure and damage costs. In 2018, Hurricane Michael hit northwest Florida as the third most intense storm to ever reach the U.S. The National Oceanic and Atmospheric Administration said the storm's pressure was 919 millibars.

Here are the 10 most intense hurricanes in U.S. history, as measured by central pressure, according to the National Oceanic and Atmospheric Administration (the lower the pressure, the more intense the storm):

1. Florida (Keys) - 1935, 892 mb

2. Camille (Mississippi, Louisiana, Virginia) - 1965, 900 mb

3. Michael (Florida) - 2018, 919 mb

4. Katrina (Louisiana) - 2005, 920 mb

5. Andrew (Florida, Louisiana) - 1992, 922 mb

6. Texas (Indianola) - 1884, 925 mb

7. Florida (Keys) - 1919, 927 mb

8. Florida (Lake Okeechobee) - 1928, 929 mb

9. Donna (Florida) - 1960, 930 mb

10. Louisiana (New Orleans) - 1915; Carla (north and central Texas) - 1961; Ian (southwest Florida) - 2022, 931 mb

Hurricane Katrina, which decimated New Orleans in 2005, is essentially tied with Michael as the third most intense to make U.S. landfall, but was by far the costlier storm. According to NOAA, Katrina, which hit the Bahamas, Florida, Louisiana, Mississippi and Alabama, resulted in $40.6 billion in insured losses and more than $108 billion in total estimated losses.

Most of the costliest hurricanes to hit the U.S. mainland have occurred since 2005, NOAA said.

7 costliest hurricanes in the U.S., adjusted to the 2022 U.S. dollar:

1. Katrina (2005) - $187 billion

2. Harvey (2017) - $149 billion

3. Ian (2022) - $113 billion

4. Sandy (2012) - $83 billion

5. Irma (2017) - $60 billion

6. Andrew (1992) - $56.3 billion

7. Ike (2008) - $40.7 billion

And these are the 10 deadliest hurricanes in U.S. history to hit the mainland:

1. Texas (Galveston) 1900, 8,000-12,000 casualties

2. Florida (SE/Lake Okeechobee) 1928, 2,500-3,000 casualties

3. Katrina (Louisiana, Mississippi, Alabama, Florida, Georgia) 2005, 1,500 casualties

4. Louisiana (Cheniere Caminanda) 1893, 1,100-1,400 casualties

5. South Carolina/Georgia (Sea Island) 1893, 1,000-2,000 casualties

6. Georgia/South Carolina 1881, 700 casualties

7. Audrey (Louisiana, Texas) 1957, 416 casualties

8. Florida (Keys) 1935, 408 casualties

9. Louisiana (Last Island) 1856, 400 casualties

10. Florida (Miami) 1926, 372 casualties

Some figures are estimated.

If hurricanes outside the continental U.S. are factored in, two hurricanes to strike Puerto Rico -- San Felipe (1928) and David (1979) -- rank among the most intense in history. And Hurricane Maria, which struck Puerto Rico in 2017, decimated the island, causing an estimated $90 billion in damage and left nearly 3,000 people dead.

Several 19th-century hurricanes to strike Puerto Rico and one in 1928 (San Felipe) and 1932 (unnamed), would rank among the 20 deadliest storms, according to NOAA.

The largest hurricane death toll on record is the Bangladesh Cyclone of 1970, when an estimated 500,000 people died due to the storm surge, according to the National Weather Service.
