So obviously she isn't planning on evolving a bunch of Magikarps into Gyarados, but her plan may be similar to a plan used in Pokemon Gold and Silver. In Gold and Silver, Team Rocket used a radio signal to force Pokemon near Lake of Rage to evolve, resulting in a shiny Gyarados.

Now lets look at what we know of the bad guys. Cinder has hacked into the largest communication tower in Vale, a tower which allows communication between all 4 kingdoms. New members of the White Fang currently are being sent to the South-East (I think it was the South-East) in order to help with some plan. Also in the South-East, the number of Grimm are increasing at an alarming rate, making it unsafe for any team below Second Years to go there on missions. Lastly, looking at the trailer Grimm will find a way into the city.

Is it possible the White Fang are working on a radio signal capable of drawing in Grimm and are planning on broadcasting this signal from every CCT Tower in order to draw all the Grimm in the area to the cities? It seems very possible. Obviously this doesn't account for the large supply of Dust, but that may be for another phase of the plan.
