Wielder of Storms translation

I thought Wielder of Storms as a given title or name could be: Maethalagos. (Maetha- to wield, control, and Alagos storm)

Is this correct?

maethor would be warrior. I would use tortha- v. “to wield, control” for torthor So it would be Torthor Gwaew or Torthor Elegys. If you want the plural storms.

Thanks!
