IF your system is plugged into separate circuit(s), (as it should be) simply turn the breaker(s) off, back on after storm passes.
WHY would you unplug if the circuit is off?
IF your equipment is plugged into a protective device, either trust your protective device, OR, unplug the protective device, thus everything plugged into it is unplugged.
In your case, or if you do not want a protective device, a high quality plug strip into your separate circuit(s), outlet end located where you can reach it, plug/unplug the pieces there.
