A heavy rainfall has occurred over Kerala state during August, 2018. This rainfall broke last 100 years flood records. Nearly 400 mm of rainfall occurred daily during 1st – 19th August, 2018. This extreme event leads to high damage to life and property. More than 500 people were dead due to the heavy landslides that were caused due to severe floods. In this study, the rainfall event was presented on Kerala region using the ECMWF ERA5 reanalysis data. We used parameters like Humidity Index (HI), Convective Available Potential Energy (CAPE) and Total Column Water Vapour (TCWV) for analyzing their influence on rainfall. Our attempt was to bring out the impact of convection influencing parameters on precipitation. Kerala region is located on the west coast of India. TPW parameters were indicating high values which support rainfall activity. The HI values were very low indicating high chances for severe convection occurrence. CAPE values were less than 1500 J/kg. These results indicate the usefulness of ERA5 satellite products for studying extreme rainfall events.
