Storm's too darn wild (7)
I believe the answer is:
tornado
'storm's' is the definition.
(tornado is a kind of storm)
'too darn wild' is the wordplay.
'wild' indicates an anagram.
'too'+'darn'='toodarn'
'toodarn' anagrammed gives 'TORNADO'.
(Other definitions for tornado that I've seen before include "Whirling windstorm" , "threat" , "Violent twister" , "Major storm" , "Violent whirlwind over land" .)
