The analysis of daily precipitation data of four climate stations in the Mexican states of Chiapas and Tabasco is presented in this paper. The period from August to November of 2007 was selected because of the big flood that severely affected the city of Villahermosa and its surroundings. The variograms and correlograms indicate that the produced precipitations are in fact far from its normal variability.
