Jen, it is not the solar storm itself that is the issue (though that could be ugly in and of itself). But if the Van Allen belts have been scrambled by polarity reversal, the energy of a major storm would hit in concentrated strings and points as it was refracted moving through the twisted belt. You could potentially have effects like a microwave beam hitting different areas that could cause huge problems, most importantly in upsetting the normal heat/cold flow patterns of air and water. That level of major instability in the atmosphere would create some hellacious storms could be of magnitudes not known in human history.
Along with it you add in massive electronic destruction, radio interruption, etc. so that communications and emergency response becomes problematic…
Look at the effects of El Nino and La Nina on weather. That is one current in one area of the Pacific that disrupts “normal” temperature change and flow. Now instead of El Nino, substitute one area of super heated water in say the Bearing Straits…
