What happened

The episode as NWS MFR wrote it up.

Another front brought marginal high winds to the coast. The only reporting station that met criteria was Cape Blanco, which recorded a peak gust of 79 mph. Usually Cape Blanco is not used to verify warnings, but this gust exceeded warning criteria by 21 mph and it is assumed that gusts to 58 mph occurred away from the Cape.
