We provide numerical evidence that electronic pre-turbulent phenomena in graphene could be observed, under current experimental conditions, through detectable current fluctuations, echoing the detachment of vortices past localized micron-sized impurities. Vortex generation, due to micron sized constriction, is also explored with special focus on the effects of relativistic corrections to the normal Navier-Stokes equations. These corrections are found to cause a delay in the stability breakout of the fluid as well as a small shift in the vortex shedding frequency. Finally, a relation between the Strouhal number, a dimensionless measure of the vortex shedding frequency, and the Reynolds number is provided under conditions of interest for future experiments.
