  abstract = {{D}evastating floods have plagued many {W}est {A}frican cities in the past decades. {I}n an attempt to reduce flood damage in {B}amako ({M}ali), an early warning system ({EWS}) demonstrator ({R}aincell {A}pp) was developed for flash floods. {O}n 16 {M}ay 2019, while the demonstrator was partially operational, an intense rainfall event led to devastating floods. {W}e carried out an experience feedback on this flood event by comparing {EWS} simulations to the results of a field survey. {G}iven the synoptic situation and the rapid development pattern of the storm, none of the global forecasting systems were able to foresee its occurrence and magnitude. {T}he hydrological model developed as part of the demonstrator correctly identified most of the locations where overbank flow occurred. {I}n the absence of data, the predicted discharge and volume values could not be validated. {H}owever, they are realistic based on the water levels reported in the {P}ost-{D}isaster {N}eeds {A}ssessment report. {I}t would be advisable to couple it to a two-dimensional hydraulic model and add discharge and water level monitoring to the already existing rainfall surveillance scheme to further improve the system's performance. {I}ncreasing the local population's awareness of the dangers of clogged waterways is also mandatory.},
