ICING
Under some conditions operation of the wind
vane will be degraded by the presence of ice.
This most often occurs as the result of freezing
rain. The condition quickly clears when sun-
shine heats the wind vane causing the ice to
melt. The condition may persist for hours or
days in the absence of bright sunshine. No
permanent damage is done to the wind vane .
