direction of maximum gust (10's deg/tens of degrees)
The direction of the maximum gust (true or geographic, not magnetic) from which the wind blows. Expressed in tens of degrees (10's deg), 9 means 90 degrees true or an east wind, and 36 means 360 degrees true or a wind blowing from the geographic north pole. This value is only reported if the maximum gust speed for the day exceeds 29 km/h.
