31 What are the most and least tropical cyclones occurring in the Atlantic basin and striking the USA?

Starting in 1944, systematic aircraft reconnaissance was commenced for
monitoring both tropical cyclones and disturbances that had the potential
to develop into tropical cyclones. This is why both Neumann et al. (1993)
and Landsea (1993) recommend utilizing data since 1944 for computing
climatological statistics. However, for tropical cyclones striking the
USA East and Gulf coasts - because of highly populated coast lines,
data with good reliability extends back to around 1899. Thus, the
following records hold for the entire Atlantic basin (from 1944-1996) and
for the USA coastline (1899-1996):

                                      Maximum        Minimum
  Tropical storms/hurricanes:        19*(1995)       4 (1983)
  Hurricanes:                        12 (1969)       2 (1982)
  Intense Hurricanes:                 7 (1950)       0 (many times,1994 last)
  USA landfalling storms/hurricanes:  8 (1916)       1 (many,1991)
  USA landfalling hurricanes:         6 (1916,1985)  0 (many,1994)
  USA landfalling intense hurricanes: 3 (1909,33,54) 0 (many,1994) 

(*) As a footnote, 1933 is recorded as being the most active of any
Atlantic basin season on record (reliable or otherwise) with 21 tropical
storms and hurricanes.

Below is a table with individual years for the numbers of named storms
(tropical storms and hurricanes) - NS, named and subtropical storms -
