wrf_map_overlays zoom fail

[JCollins]

Hello everyone.

I have created a simple script in NCL, in which the wind vectors are drawn at 10 m. Also, I try to zoom the domain, but it does not draw the latitude and longitude indicated in the script. The latitude and longitude is random.

Can someone help me find the error?

Thank you very much to all.
