Weather alert Notify 2 people (create group?)

Configuration
1

I have a weather alert set up with the code below to alert me.
I know want to add my wife to get the same alerts, but I do not understand how to create a group notify.
If I wanted to add notify.anne what would I do.
Need advice on how to do it.
Thanks

    - service: notify.carlton
