Post-storm analysis on Hurricane Michael has revealed that the estimated intensity at landfall was 140 knots (160 mph), making it the fourth Category 5 storm on record to hit the United States. The storm made landfall on October 10, 2018, near Mexico Beach and Tyndall Air Force Base, Florida. The storm was the first Category 5 storm to strike the United States since Hurricane Andrew hit in 1992. The other two Category 5 hurricanes to make landfall in the U.S. are the Labor Day Hurricane in 1935 and Hurricane Camille in 1969.
The decision to reclassify Hurricane Michael from a Category 4 to a Category 5 storm comes after a detailed post-storm analysis by NOAA’s National Hurricane Center. Data from available aircraft winds, surface winds, surface pressures, satellite intensity estimates and Doppler radar velocities was used in determining the estimated maximum sustained wind speed.
