Stormed wildly, upsetting Edgar (5)

I believe the answer is:
raged
'stormed wildly' is the definition.
'raged' can be an answer for 'stormed' ('rage' can be a synonym of 'storm'). I am not sure about the 'wildly' bit.
'upsetting edgar' is the wordplay.
'upsetting' indicates an anagram.
'edgar' with letters rearranged gives 'RAGED'.
Can you help me to learn more?
(Other definitions for raged that I've seen before include "Spoke violently" , "Fumed" , "Behaved violently" , "Spoke loudly and angrily" , "Expressed intense anger" .)
