1870/01: No major changes from Partagas and Diaz's (1995a) analysis.No track available, only one point. Storm is determined to have reached hurricane status based upon damage reports from Mobile, Alabama. Storm is also known as the "Mobile Storm of July 1870" in Ludlum (1963).

1870/02: No major changes from Partagas and Diaz's (1995a) analysis. Stormis determined to have reached hurricane status from several ship reports.

1870/03: No major changes from Partagas and Diaz's (1995a) analysis. Ship with central pressure observation of 1004 mb gives 39 kt with new southern wind-pressure relationship, thus 40 kt is assigned to the best track.

1870/04: No major changes from Partagas and Diaz's (1995a) analysis. Ship with central pressure observation of 948 mb gives 98 kt with new northern wind-pressure relationship, thus 100 kt is assigned to the best track. Storm is suggested to have reached major hurricane status based upon the above central pressure reading.

1870/05: No major changes from Partagas and Diaz's (1995a) analysis. Ship with central pressure observation of 969 mb gives 83 kt with new northern wind-pressure relationship, thus 80 kt is assigned to the best track. Storm is determined to have reached hurricane status based upon above central pressure reading as well as several ship reports.

1870/06: No major changes from Partagas and Diaz's (1995a) analysis. Central pressure observation over Cuba of 969 mb gives 91 kt with new southern wind-pressure relationship, thus 90 kt is assigned to the best track. Storm is determined to have reached hurricane status based upon the above central pressure measurement, several ship reports and destruction that occurred in Cuba.

1870/07: No major changes from Partagas and Diaz's (1995a) analysis. No track available, only one point. Storm is determined to have reached hurricane status based upon report from the ship "Horatio Harris".

1870/08: No major changes from Partagas and Diaz's (1995a) analysis. Storm is determined to have reached hurricane status based upon several ship observations.

1870/09: No major changes from Partagas and Diaz's (1995a) analysis. Inland winds over Cuba and Florida reduced via Kaplan and DeMaria's (1995) inland decay model. Storm is determined to have reached major hurricane status at landfall in Cuba based upon severe damage in Vuelta Abajo and Batabano.

1870/10: No major changes from Partagas and Diaz's (1995a) analysis. No track available, only one point. Storm is determined to have reached hurricane status based upon observations from the ships "R. Murray, Jr." and a Spanish bark.

1870/11: No major changes from Partagas and Diaz's (1995b) analysis. Inland winds over Mexico reduced via Kaplan and DeMaria's (1995) inland decay model with an accelerated rate of decay to account for the enhanced topography. Storm determined to have reached hurricane status based upon reports from ships "Silver Star" and "Nymph".
