      How can the wind be no more than 20mph all this weekend around Healdsburg, CA AND the WIND GUSTS be over 45mph !! Surely there's an error !
      This is crucial as there is a mass evacuation order of 38,000 people !!!

        This might help explain how ECMWF calculates the surface wind and gusts speeds.

        In my view, this is not a perfect relationship for gusts and I have seen many situations where the forecast gust speed has been over/under estimated.
