“…These are not typical figures; this was a major tsunami that caused significant damage and loss of life. It has been suggested [16] that an HF radar needs to be able to resolve an anomaly in surface current of less than 0.05 m•s −1 to detect hazardous tsunamis near the coast and issue useful alerts.…”

A real-time alert issued by a high frequency (HF) Wellen radar (WERA) at Tofino on January 5, 2020 was identified as a possible meteotsunami because of the anomalous surface currents. Reanalysis of the HF radar data and consideration of associated meteorological data from Global Forecast System North West Pacific forecasts, the GOES-17 weather satellite and the NDBC buoy at La Pérouse, indicate that the anomaly in ocean currents was a combination of a wind setup at the coast over several preceding hours and an abrupt change in wind direction driven by the passage of a severe cold front. It is unlikely that the Proudman resonance condition between the wind speed and gravity wave phase velocity existed, except perhaps very close to the coast. The inclusion of the wind direction measurements by the HF radar will improve the real-time alerts at the coast by discriminating between tsunamis and wind-driven storm surge events.
