Abstract
The flash flooding across Central Texas on 4 July 2025, caused more than 130 fatalities and property losses exceeding USD 20 billion. The objective of this study is to evaluate the performance of the NOAA operational flood forecasting pipeline, including Quantitative Precipitation Forecasts, National Water Model short-range streamflow forecasts, and Office of Water Prediction flood inundation mapping during this catastrophic event, and to characterize how forecast skill and impact-based predictions varied with forecast lead time at gauged and ungauged locations. Using the Operational National Water Model short-range streamflow forecast product, we generated 306 forecasted flood inundation maps between 3 and 4 July 2025. For evaluation, we constructed an inundation extent benchmark derived from USGS high water marks. Both impact based and skill-based assessments are presented.
Predicting flood dynamics in data-scarce urban catchments remains a major hydrological challenge, yet physically-based modeling is essential for design mitigation infrastructure. This study assessed the impact of land cover change on the hydrological response and hydraulic performance of the ungauged Kinalumsan River i...

In May 2019, unprecedented extreme rainfall over the central United States (US) facilitated severe flooding along the Arkansas River. The well‐documented relationship between atmospheric rivers (ARs) and central US heavy precipitation motivated investigation into AR relevance to this event and its predictability on ext...

Atmospheric rivers (ARs) are a major driver of hydrometeorological extremes along the U.S. West Coast, yet their role in generating events with high compound flood potential remains poorly understood and quantified. Here, we assess the contribution of ARs to compound flood potential by analyzing the joint occurrence of...

Flood peaks can develop and recede within a day, making them difficult to capture with satellites with multi‐day revisit intervals. Here, we exploit daily observations during the Calibration and Validation phase of the SWOT mission to examine a short‐lived flood in May 2023 along the Du Gouffre River in Canada. Despite...

Flood forecasting is an effective disaster management and risk reduction tool, especially as climate change and urbanisation increase the frequency and intensity of flood events worldwide. We propose a flood inundation forecasting system incorporating a copula-corrected forecast rainfall mechanism to rectify the spatio...
