Waves from hurricanes Lili and Isidore were measured using an ADCP directional wave gauge and an independent pressure sensor. Data demonstrates the effects of strong storm surge induced currents on wavenumber. We investigate the effect of Doppler shifting of wavenumber to wave height estimates and wave direction. Comparison data is used from direct surface measurement and a co-located PUV sensor to show the extent of errors introduced by currents. The importance of accurately measuring wave heights during extreme events underscores the value of addressing significant error sources associated with storm surge.
