Fırtına or Peruma is one of the main water streams of Rize Province in the eastern Black Sea Region of Turkey.
Its name is Turkish for "storm water".
There is a group of more than 20 well-preserved Ottoman-era bridges over the Fırtına Deresi.
The Fırtına Deresi rises in Kaçkar Mountains in Rize Province and flows to the Black Sea, passing Çamlıhemşin and Ardeşen.
