After the rain/snow mix we had today and then the temp dropping below freezing, my anemometer is now frozen.
You can see the “little” bump in speed about 16:00, from when I tapped the cups with a pole. That has done the trick in the past, but not today. We’ll just have to see if it warms enough tomorrow to thaw them out.

Today’s warmer temp’s thawed everything out.
