  The pattern of migrating zonal flow bands associated with the solar cycle,
known as the torsional oscillation, has been monitored with continuous global
helioseismic observations by the Global Oscillations Network Group, together
with those made by the Michelson Doppler Imager onboard the Solar and
Heliosepheric Observatory and its successor the Helioseismic and Magnetic
Imager onboard the Solar Dynamics Observatory, since 1995, giving us nearly two
full solar cycles of observations. We report that the flows now show traces of
the mid-latitude acceleration that is expected to become the main
equatorward-moving branch of the zonal flow pattern for Cycle 25. Based on the
current position of this branch, we speculate that the onset of widespread
activity for Cycle 25 is unlikely to be earlier than the middle of 2019.
