     abstract = "{Landfalling hurricanes pose significant hydrological risks, yet
        monitoring their terrestrial water storage (TWS) dynamics
        remains challenging. Here we employed a new technique that
        estimates daily regional gravity changes from orbital
        perturbation measurements of the Gravity Recovery and Climate
        Experiment and its follow-on mission to characterize TWS
        variations during Hurricanes Katrina (2005) and Laura (2020).
        Our spatiotemporal water storage maps reveal
        {\ensuremath{\sim}}40 Gt of accumulation by Katrina and a
        coastally localized {\ensuremath{\sim}}15 Gt by Laura, with
        coastal regions retaining up to 80\% of precipitation but
        draining several days faster than inland areas. Despite
        differing magnitudes, both storms exhibited similar
        precipitation-to-TWS conversion patterns, implying consistent
        scaling of hydrological responses across intensities. Our
        observations also indicate that current land surface models,
        lacking surface inundation modeling, result in underestimations
        of flood recession rates. This work highlights satellite
        gravimetry's potential for continuous hurricane-induced flood
        monitoring, offering a new tool to alleviate current
        observational difficulties.}",
