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.
Meteorological history of Hurricane Andrew
On August 19, a Hurricane Hunters flight into the storm failed to locate a well-defined center, and the next day a flight found that the cyclone had degenerated to the extent that only a diffuse low-level circulation center remained; observations indicated the pressure rose to an unusually high 1015 mbar. The flight indicated Andrew maintained a vigorous circulation aloft, with winds of recorded at flight level. Subsequently, the upper-level low weakened and split into a trough, which decreased the wind shear over the storm. Simultaneously, a strong high pressure cell developed over the southeastern United States, which built eastward and caused Andrew to turn to the west. Convection became more organized as upper-level outflow became better established. An eye formed, and Andrew attained hurricane status early on August 22, while located about east-southeast of Nassau, Bahamas.
