Apart from whatever you may read at the national level, North Carolina still has on the books a law prohibiting carry off one's property when any state of emergency exists.
From http://www.jus.state.nc.us/NCJA/ncfirearmslaws.pdf :
"5. Areas of Emergency and Riot
It is also a misdemeanor under North Carolina law for a person to transport or
possess, off his or her own premises, a dangerous weapon in an area during a declared
state of emergency, or in the vicinity of a riot. N.C. Gen. Stat. § 14-288.7 A concealed
handgun permit does not allow a permittee to carry a weapon in these areas. N.C. Gen.
Stat. § 14-415.11(c)"
This law needs to go, at the very least the emergency part. Until then, whether a misdemeanor is worth risking to protect oneself in such a situation by being armed, is a personal decision.
