This study was conducted to analyse the occurrence of extreme rainfall and dynamics atmosphere prior flood events in South Sulawesi during September-October-November (South Sulawesi’s dry season). The data used is daily for period 2001-2020. Using 50 mm/day 90th percentile threshold 119 rain stations distributed over 24 regencies, each region were identified. Furthermore, after screening followed by events, a composite analysis carried out obtain patterns atmospheric conditions before events. results confirm that spatially, highest indices values dominate western northern regions Sulawesi, both frequency intensity indicators. Flood 2001-2020 recorded as 23 days, which 19 days event showed anomalies precipitable water, 850 mb winds, 200 winds. An increase amount water wind speed mb, well decrease 250 compared normal its surroundings, has resulted an formation clouds have potential chance rainfall.
