Hurricane Ian is out of Florida and moving north up the East Coast. It was a strong one and joins the top hurricane list.

Hurricane Ian made landfall Wednesday afternoon near Fort Myers, Florida, as one of the more intense storms ever to hit the United States. Packing 150 mph winds and a minimum central pressure of 940 millibars, or 27.76 inches, at landfall, Ian was just shy of becoming a Category 5 hurricane.  Going by preliminary measurements of the storm’s minimum pressure alone, Ian would be the 22nd strongest storm recorded in the U.S., according to the Atlantic Oceanographic & Meteorological Laboratory and other government agency reports. Although there are several factors that play into the damage a storm can cause, a low minimum central pressure allows for stronger winds.  A millibar is a unit of atmospheric pressure, as measured by a barometer.

These are the top storms by millibars. THe final tally is also dependent on the damage caused.

Here’s are 10 of the strongest hurricanes ever to hit the U.S.: 892 millibars – A Category 5 storm hit the Florida Keys in 1935, 15 years before the National Hurricane Center began naming hurricanes, 900 millibars – Hurricane Camille swamped southeast Louisiana and south Mississippi as a Category 5 storm in 1969, 920 millibars – Hurricane Michael, a Category 5 storm, hit northwest Florida in 2018, and Hurricane Katrina crippled southeast Louisiana and south Mississippi in 2005 as a Category 3 storm, both at 920 millibars. Katrina remains the costliest storm in U.S. history, 922 millibars – Hurricane Andrew in 1992 hit southeast Florida as a Category 5 storm and south central Louisiana as a Category 3, 925 millibars – An unnamed Category 4 storm came ashore at Indianola, Texas, in 1886, 927 millibars – An unnamed Category 4 storm struck the Florida Keys and southwest Texas in 1919, 929 millibars – Hurricane Ida hit Louisiana as a Category 4 storm in 2021, and an unnamed Category 4 hurricane hit Lake Okeechobee, Florida, in 1928, both at 929 millibars and 930 millibars – Hurricane Donna hit Florida and other parts of the eastern United States in 1960.

A good listing and many hit Louisiana. A surprising number with out names.
