In this investigation, we analyzed expressive daily accumulated of pluvial precipitation that occurred in March 2019 in the State of Ceará, in order to identify if they were considered extreme (from the Statistical Methodology of the Maximum Precipitation), and to analyze the atmospheric systems that started such events and possible damage caused by them. The ten largest daily accumulations of March recorded in the posts of the Foundation for Metereological and Hydric Resources of Ceará State (FUNCEME) were selected. At the same time, the atmospheric systems that contributed to these pluviometric episodes were identified from satellite images provided by the National Institute of Space Research (INPE). Daily accruals were at least one of the three largest already registered at the stations (five were records) and were associated with joint performance of two or more atmospheric systems. Atlantic TMSM (near the coast) showed a favorable pattern for precipitation. The daily accumulations were punctual and allowed a considerable contribution only in some water reserves of the Ceará State, because the rain did not present a homogeneous spatial/temporal distribution.
