        importance of identifying their precursors and enhancing
        resilience to these events. Here, we calculated Antecedent Total
        Water Storage (ATWS) anomalies from the new 5-day (5D) Gravity
        Recovery and Climate Experiment (GRACE) and its Follow-On
        (GRACE-FO) satellite solutions to enhance the detection of pre-
        flood and active flood conditions and to map post-flood storage
        anomalies. The GRACE data were compared with
        \raisebox{-0.5ex}\textasciitilde 3300 flood events reported by
        the Dartmouth Flood Observatory (2002{\textendash}2021),
        revealing distinct ATWS precursor signals in 5D solutions, in
        contrast to the monthly solutions. Specifically, floods caused
        by saturation-excess runoff{\textemdash}triggered by persistent
        rainfall, monsoonal patterns, snowmelt, or rain-on-snow
        events{\textemdash}show detectable ATWS increases 15 to 50 days
        before and during floods, providing a valuable opportunity to
        improve flood monitoring. These 5D solutions also facilitate a
        more rapid mapping of post-flood storage changes to assess flood
        recovery from tropical cyclones and sub-monthly weather
        extremes. Our findings show the promising potential of 5D GRACE
        solutions, which are still in the development phase, for future
        integration into operational frameworks to enhance flood
        detection and recovery, facilitating the rapid analysis of
        storage changes relative to monthly solutions.}",
