Clearing old weather data

In the not-too-distant future I will be relocating to a different area and would like to clear out all of the existing weather data and start fresh.

Is there a way to do this? I’m using Weather Display 10.37R Build 23 (Registered).

Thank you.

Are you talking about your CWOP data, or all of WD?

Just the data in WD. I will be issued new CWOP and MADIS IDs.
