Description:Over the past 15 years and through multiple large and devastating earthquakes, tsunami warning systems have grown considerably in their ef ficacy in providing timely and accurate forecasts to affected communities. However, one part of tsunami warning that still needs improvement is forecasts catered to local, near ‐field communities in the time after an earthquake rupture but before coastal inundation. In this study, we test a rapid, Global Navigation Satellite Systems (GNSS) ‐driven earthquake characterization model using a large data set of synthetic megathrust ruptures for its near ‐field tsunami forecasting potential. We also provide a framework for tsunami forecasting that focuses on the likelihoodof exceedance of user ‐defined coastal amplitudes that may be of use in the first 15 min following an
