Has Crocodile already "awakened" his Devil Fruit Power?
From how I see it and how it's described in the series, the awakening is the ability to manipulate the environment e.g. Doflamingo's awakening. Like when Kuzan and Sakasuki went at it on punk hazard and permanently changed the weather.

Another example is when Crocodile turned everything around him into the sand during his second fight with Luffy (Mizu Luffy)(Chp 201). Also, there are the times Crocodile talks about "utilizing your devil fruit better"(Chp 178) or being "a different breed of pirate"(Chp 178) though this may just be Crocodile being cocky. He seems to have a vast knowledge of devil fruit awakenings anyway as he was the one who informed us about the jailer beasts being awakened and even told us the effects had on them.(Chp 544)

Also, once he was defeated, it started to rain again(Chp 210), and though many people say "Oh, Smoker used the dance powder on Crocodiles ship" or "Crocodile used the dance powder another place to keep it from raining", but Smoker specifically said to Hina that he didn't (Chp 212) and that would have to be perfect timing so I think Crocodile is awakened and can keep his devil fruits weakness away.
