Analysis of the two previous decades (1851-1870).

Over the 19 years embraced in the analysis period, five or six T. C. of consideration affected Cuba. However, it is difficult to assure the accuracy of this with certainty.

Melero, Fernández de Castro, Tannehill and Rodríguez Ramírez include in their chronologies the following ones:

Table 1. Hurricanes affecting between 1851 and 1869. According to different chronologies.

A chronology published by Martínez Fortún in 1948 was not taken into account, because only meteors that crossed on the Villa of San Juan de los Remedies or its suburbs were registered. Neither it was possible to use for the characterization of this period father Mariano Gutiérrez-Lanza’s excellent chronology (1926), because its compilation begins in the year 1865.

After having concluded an interesting investigation on the hurricanes of the second half of the XIX century in the Atlantic Ocean, Fernández-Partagás and Díaz (1996) they have been able to determine the trajectories of numerous new tropical systems whose existence was ignored. Starting from those results, we insert here the figures published by their authors for the period 1851-1870:

Chart 2. Number of already known and new hurricanes identified in the second half of the XIX century.

We consider possible that some other tropical system may have crossed over Cuba or its vicinity during that period without being detected by the observers and, consequently, not been included in any of the mentioned chronologies.

Up to 1870, the last T. C. of remarkable intensity that had affected the City of the Two Rivers was San Francisco de Asís's Storm (October 4 - 5 1844), catastrophic in Havana and also in Matanzas. In this last place it registered at the time a minimum of 948 hPa.
