Seven rain gauges located in the basin were analyzed using the Modified Fournier Index. It was demonstrated that the rain gauge CA-39, 83.3% of the values are within the category very low or moderate climatic aggressiveness, 16.8% correspond to high and very high. It was evidenced that CA-673, CA-676 and CA-843 rain gauges show the highest impact rates with values of 19.5%. The rain gauges CA-886, CA-887 and CA-890 only indicated a moderate climatic aggressiveness. The extreme values of climatic aggressiveness were adjusted to the Gumbel Probability Distribution Function, yielding equations that predict the behavior of this phenomenon. In the investigation, the period of return (T) 5, 10, 15, 20, 30 and 35 years is proposed for the prediction. En la investigación se determina el efecto potencial de las precipitaciones sobre el suelo y la vegetación en áreas de la cuenca Chambas, Ciego de Ávila, Cuba. Se analizaron siete pluviómetros situados en la cuenca utilizando el Índice de Fournier Modificado. Se demostró que el pluviómetro CA-39, el 83.3% de los valores están dentro de la categoría muy baja o moderada agresividad climática, 16.8% corresponden a altos y muy alta. Se evidenció que en los pluviómetros CA- 673, CA-676 y CA-843 presentan los mayores índices de impactos con valores de 19.5%. Los pluviómetros CA-886, CA-887 y CA-890 solo indicaron una moderada agresividad climática. Los valores extremos de agresividad climática se ajustaron a la Función de Distribución de Probabilidad de Gumbel, arrojando ecuaciones que predicen el comportamiento de este fenómeno. En la investigación se propone para el pronóstico el período de retorno (T) 5, 10, 15, 20, 30 y 35 años.
