Overall for maximum U.S. impact:  1 hurricane upgraded 3 categories, 2 hurricanes upgraded 2 categories,

1 hurricane downgraded 2 categories.

Saffir-Simpson:  The estimated Saffir-Simpson Hurricane Wind Scale at landfall based upon maximum sustained 
(1-min) surface (10 m) winds.  "(TS)" indicates the cyclone was considered to be of tropical storm impact 
for the United States. "(EX)" indicates the cyclone was considered to be extratropical when it made landfall 
in the United States.

States Affected:  The impact of the hurricane upon individual U.S. states by Saffir-Simpson Hurricane Wind 
Scale (again through the estimate of the maximum 1-min surface winds at each state).  (ATX-South Texas,

roughly from the Mexico border to Corpus Christi; central is from north of Corpus Christi to Matagorda Bay 
and north is from Matagorda Bay to the Louisiana border.  In Florida, the north-south dividing line is from 
Cape Canaveral [28.45N] to Tarpon Springs [28.17N].  The dividing line between west-east Florida goes from 
82.69W at the north Florida border with Georgia, to Lake Okeechobee and due south along longitude 80.85W.)
