Notes:

" " = Not available in original HURDAT

Named Storms = Tropical Storms, Hurricanes and Subtropical Storms

Hurricanes = Saffir-Simpson Hurricane Scale 1 to 5

Major Hurricanes = Saffir-Simpson Hurricane Scale 3, 4, or 5

"ACE" - Accumulated Cyclone Energy = An index that combines the numbers of systems, how long they existed and how intense they became. It is calculated by squaring the maximum sustained surface wind in the system every six hours that the cyclone is a Named Storm and summing it up for the season.

It is expressed in 10 to the 4th kt**2.

U.S. Hurricanes = Number of Hurricane strikes on the continental United States. Inside the parenthesis is the highest Saffir-Simpson Scale category for each U.S. hurricane at landfall.

Red highlight indicates that revisions have been made. The remainder of the 20th century is currently under revision.
