That’s a bit of an assumption, there’s some lore hints that the Warp Storms weakening might have been more deliberate than previously implied.
The idea being Slaanesh’s birth is what made the other Chaos Gods really sit up and take notice of how much free psychic power an evil galactic empire of murder monkeys can generate, so when Useful Idiot McGenocide was ready to start conquering they made it so that he could and cleaned up Slaanesh’s afterbirth as it were.
Of course, it’s 40k, there’s all kinds of lore hints that never get any further explanation.

Assuming the Chaos Gods have that kind of control over the Warp of course (I honestly don’t know whether or not they can cause warp storms, there’s still a lot of 40k lore that I don’t know that well). It’s possible as well that the Emperor knew when the warp storms would clear up and chose that time to start forming the Imperium to get ahead of the Xenos.
That is typical of 40k lore though, everything is left vague and having multiple possible interpretations, and story threads are started then abandoned all over the place. It’s all just to facilitate sales of model kits in the end.
