How much accurately location of the falling failing artificial satellites on earth may be predicted?

To forwarn the public and take preventive measures

Hi, it is difficult to give you a figure. Concerning reentry trajectories, the gravitational influence of the Earth is known with a high precision. The main source of uncertainty comes from the atmospheric drag. Hopefully the satellites are falling in the ocean, thus a very high precision on the falling point is not mandatory.
