Feds Have a Plan For Catastrophic Solar Flares (digitaljournal.com)
New submitter Steve Sacco, referencing the newly released National Space Weather Strategy and the National Space Weather Action Plan, written in anticipation of large-scale disruptions from a solar flare or similar event, writes: Released on October 28, 2015, the White House plan involves the coordination of agencies from the federal level, state level, and including emergency managers, academia, the media, the insurance industry, nonprofit organizations and the private sector, all in preparation for the worst-case scenario possible, such as the Carrington Event that took place in 1859.

No, there is a better preparation, ground resistors for transformers so the grid doesn't even need to be shut down. Solved problem, just need to spend the money and do it; estimated cost by Michio Kaku and other members of the American Physical Society was less than $200 million. chump change, cheap insurance.
This.
The electrical grids consist of cables that are strewn over long distances. They act like giant antennas that pick up the EM radiation from the flare and its interaction with the Earth's magnetic field. To protect the grid, you disconnect portions of it from each other, so that instead of a few giant "antennas", you have many more small ones. The current induced in the smaller "antennas" is much lower and far less harmful. And this is why prediction is so important: the early warning allows grid-operators to disconnect the grid in time to avoid catastrophic damage.
Satellites are also vulnerable because they can suffer deep static-charging that burns out electrical components. Unfortunately, forecasting doesn't help as much for this. The best you can do is study the magnitudes of expected events, engineer as well as you can against them, and plan for redundancy and replacement of the satellites as needed.
If it weren't for deadlines, nothing would be late.
If you don't have solar power stored in a nice dark box inside a Faraday cage, along with (at least) a radio and anything electrical you need to survive
We're talking about a solar flare, not an EMP from a nuke at ground zero. The only reason massive solar flares damage things is because we have millions of miles of wires stretched across entire continents acting like massive antennas absorbing the energy from the flare on a massive, massive scale. The primary risk is the infrastructure itself going down - mainly in the form of tens of thousands of power transformers being destroyed. It's also possible that anything plugged into the grid can also be damaged, similar to a lightning strike, however in all likelihood the grid would be damaged before it can transfer the power of the solar flare into homes (it would be a slow build up over time - hours and maybe days - until it cooks the transformers and other equipment designed to regulate power).
So Faraday cages and the like to protect from solar flare are, well, about as useful as tin foil hats. Main thing is to disconnect your house from the grid via your main breakers when we know CME strike is imminent (and of course we will know about many hours in advance).

Auroras: spaceweather.com does daily aurora reports. Check them out. Auroras are not, generally, predictable; they are more common during times of geomagnetic storms, but sometimes happen when geomagnetic activity is low, and are sometimes absent when the activity level is high.
There is no need for "hardened" equipment, only properly working circuit breakers. The onset of a geomagnetic storm is slow, over the course of hours. All that you need is a circuit breaker that trips when excess current is seen. Stuff like this has already worked in the past, like the blackout in Quebec that was caused by a geomagnetic storm. Yes, the power goes out during the storm, but as soon as the storm is over you just reset the system and there is no permanent damage.
The only place there is serious risk is places where circuit breakers have not been properly set up. And it won't probably be the first ones that trip that cause the problem, but a cascade as the demand shifts to other lines. We've had this problem with non-solar related black outs cascading before, and often it involves circuit breakers that didn't have the correct current rating set and/or were poorly maintained. The cascading of loads is much faster than the timescale of the storm itself. There is also potential for issues on systems that have breakers based purely on AC signals that would miss the relatively DC effects of the storm, but this is pretty uncommon in first world power grids, and ultimately will trip AC circuits anyway when the transformers start to saturate.
To be fair, there's not much incredibly unique about solar weather like this that wouldn't apply to a general electrical catastrophe from an intentional EMP. There's a chance of getting some notice notice, but the practical effects of that will be slim other than telling anyone with a Faraday Cage to close and everyone else to attempt to power everything down first.
Sorry, but you and the mods need to learn there is a huge difference between an EMP and a geomagnetic storm, and that the latter has nothing to do with Faraday cages and telling everyone to shut things down.
Geomagnetic storms involve magnetic fields changing on the hour timescale. Induced voltage is proportional to the area of a loop of wire and inversely proportional to the timescale involved. That very slow timescale means the induced voltages will be insignificant for anything that doesn't involve many kilometers of wire covering enough ground that the area involved in the wire or the ground itself is large enough to cause significant changes in voltage.
There would be no impact on small scale electronics, especially anything disconnected from the grid. Faraday cages won't do much, as the skin depth of something that slow is several meters in a conductor. So it would be more like shielding something from a DC magnetic material, not that it would do any good as you would need to cover thousands of square kilometers of power distribution networks and ground.
What you need instead is simply circuit breakers that can cut connections when DC current is too high, and there are even ways of wiring the transformers to ground better to mitigate the need to cut power in the first place. Head knowledge of the storm is most useful for satellite controllers than can just put satellites to sleep, as they are dealing with increased flux of particles from solar wind and radio communication problems that have potential to create fake signals in the controllers and orientate them in a useless way. It is also useful to help be prepared for large scale tripping of breakers on a power grid so as to watch out for cascading problems from improperly configured breakers and connections.
EMPs from man made sources on the other hand are mostly much faster. Nuclear weapons can produce a couple different EMP components that have different timescales, including one that is slower and more like a geomagnetic storm. But the big concern there tends to be the much faster time scale, and faster timescale means it can induce voltages in much smaller things, like stuff that is disconnected from the grid, and things that wouldn't have a circuit breaker involved like your house wiring and power grids.
Geomagnetic storms is not an end of technology based life, but about disruptions (not complete destruction) of power distribution and satellites. It is a potential source of massive economic problems, but that involves a different kind of prep much more boring than what you would see in a TV show.
I don't care if you do or don't believe anything I or anyone else says. Confirm it on your own, or don't. I don't care.

"Remember, during Katrina, Sandy, and other disasters, no other country offered aid to the US (which is ironic because the US spends a lot of cash on aiding other nations)"

Some of them even have their own extensive wiki page.

Wow, looks like the whole world tried to help you out. People, money, equipment, doctors, emergency shelter and supplies! Of course the irony is with a solar flare event, most of the world will be hit. So they won't be able to help you out either.
I do find Americans responses to disasters interesting. In many countries, it brings people together, often in the US (or at least some parts) it drives the nation apart.
100% grade A baloney. This entire post is a radical survivalist's fantasy of what they think should have happened after a national-scale natural disaster, and bears no resemblance to what actually did happen. During the Sandy situation citizens of the New York City region showed for the second time in 14 years that they are far more resilient and cooperative than the average American. "+4 Interesting" - sheesh.

I live about 50 miles by road south of NYC. Closer as the crow flies. Nothing like this happened for Sandy (or Irene the year before). If anything, the event brought people closer together. Functioning power and cell phones were rare for a couple weeks, and gas got scarce fast (mostly due to lack of power for pumps). But we had a notable lack of marauders, and the neighbors showed a very strong preference for canned food over eating each other. People shared and generally acted like a right-wingers nightmare, coming together as a community to get through it together.
