Meteorological history of Hurricane Andrew
In 2002, the "Atlantic Basin Hurricane Database Reanalysis Project" examined Hurricane Andrew and this corridor of extreme winds embedded within Andrew's northern eyewall. The project concluded that Category 5 conditions on land occurred only in a small region of southern Dade (now Miami-Dade) County, specifically close to the coast in Cutler Ridge. The remaining areas affected by Andrew's initial landfall in Florida likely experienced sustained Category 4 and 3 hurricane conditions. Andrew was officially re-classified as a Category 5 storm in 2004, and the reanalysis provided a more comprehensive and detailed examination of Andrew's wind field structure upon landfall than originally assessed in 1992.

Ten storms attained hurricane status, with winds of 75 mph (119 km/h) or greater.Of the eleven Atlantic cyclones known for 1870 only three made landfall. Although Hurricane One caused damage in Alabama, the storm centre may not have crossed the coastline.
