Please check you prepper plans and compare them to this list (not comprehensive) of actions to take AFTER an EMP event. It does matter what the source of the EMP event may be. If it was a Solar Mass Ejection, it is unlikely to be repeated in the immediate future. The same cannot be said for an attack using a nuclear weapon induced EMP.
http://urbansurvivalsite.com/actions-must-take-emp-attack/With my comment (above) in mind, I recommend NOT immediately taking all your electronics out of their Faraday Cage storage. Take out one radio (and power supply if needed). Use the radio to scan for any information being broadcast.
A nuclear induced EMP may still leave some distant radio stations in operation. Gather information.
A Solar Mass Ejection is likely to affect a larger section of the globe, with fewer radio broadcast station still online.
I hope this helps with your plans.
