20th Anniversary Of Hurricane Andrew | Real Science
In August 1992, Hurricane Andrew struck Florida with 145 MPH winds. It was the last category five hurricane to hit the US. The second highest land wind speeds (135 MPH) were at the Indianola hurricane of 1886.

By contrast, the highest land wind speeds from Katrina were 110 MPH

It has been seven years since a major hurricane hit the US, the longest such period in US history.

One might object that state temperature records are not informative, because the number of data points — 50 — is so small. So Christy also investigated “the year-by-year numbers of daily all-time record high temperatures from a set of 970 weather stations with at least 80 years of record.” He explains: “There are 365 opportunities in each year (366 in leap years) for each of the 970 stations to set a record high (TMax).” Adding the TMax days by year, Christy found that there were several years with more than 6,000 record-setting highs before 1940 but none with record highs above 5,000 after 1954. “The clear evidence is that extreme high temperatures are not increasing in frequency, but actually appear to be decreasing.”
