Caribbean Sea and the Atlantic Northeast Ocean have been characterized as a zone of high probability for the beginning, evolution and occurrence of impacts by tropical cyclones, according to National Organization for Atmospheric and Oceanographic (NOAA). Mayor events have occurred both in space and timeless along the Caribbean Tropical Cyclones passway. David (1979), Georges (1998), Noel and Olga (2007), Emily and Irene by 2011, are some of these meteorological events that put in evidence the urgent need to assess its effects not only by the magnitude of the winds, but by generating extreme rainfall. Following a review of cyclones that have affected the Dominican territory from 1851 until 2012 extracted from HURDAT-NOAA and ONAMET, an exhaustive analysis to quantify extreme rainfall using different methods are presented for the estimation of statistical of hourly series from daily (SCS Type-III Rainfall; SCS Hyetograph; Hyto-Bacht Processing based on Bartlett-Lewis; Hourly Statistical Patterns Scales Disaggregation Methods and TRMM Rainfall Database Analysis), assisting with help of models, which would simulate streaming flows that generate large floods in three considered catchment under study in the country. A summary of the state of the art and a methodology proposal for a doctoral thesis are presented in this article by the author.
