 Although extrapolated peak winds based on whatever reports are available exist for every storm in 1861, estimated minimum barometric air pressure listings are only present for the three storms that directly affected the United States.Two hurricanes during the year made landfall on the mainland United States, and as they progressed inland, information on their meteorological demise was limited.As a result, the intensity of these storms after landfall and until dissipation is based on an inland decay model developed in 1995 to predict the deterioration of inland hurricanes.
