Abstract: The intriguing possibility of employing future ground‐based gravitational‐wave interferometers to forecast short gamma‐ray bursts (GRBs) is explored. The forecasting prospect is quantified in terms of an advance‐warning time: the binary‐neutron star (BNS) inspiral time (to merger) from when the interferometer network accumulates a signal‐to‐noise ratio of 15. As sources for the Advanced LIGO–Virgo (ALV) network of 2020, BNS systems at luminosity distances of D ⩽ 200 Mpc are considered, and similarly, BNS systems at D ⩽ 1000 Mpc for Einstein Telescope. It is shown that the ALV network will provide a few minutes of warning time, thus will not forecast GRBs in the 2020s. On the other hand, Einstein Telescope will provide advance‐warning times of more than 5 hours for D ⩽ 100 Mpc. Taking 1 hour as a benchmark advance‐warning time, a corresponding BNS range of roughly 600 Mpc is obtained for Einstein Telescope. Using current BNS event rates, it is shown that Einstein Telescope will forecast GRBs in the 2030s. This warning‐time computation is reapplied to black hole–neutron star inspirals and it is found that one to three tidal disruption events are expected to be forecast by the same detector.
