Could we have a warning system to warn us of imminent geomagnetic storms?

Would it be possible, either right now or in the future, to have a warning system to advice of if a geomagnetic storm becomes imminent, so that we have time to intervene such as by putting our electronics in Faraday cages (ex.: the microwave)?

Inspired by an attempted April Fool done by my cousin saying all electronics should be closed as a geomagnetic storm would hit for the next 3 days; got me looking for evidence for a few minutes :P

My guess is that it's not possible, but I don't know.
