Why are gun sales banned because of snow in King, North Carolina?

One county to the west of my position in King, North Carolina, the authorities have banned the sale of guns and ammunition during the "state of emergency" there caused by the winter storm of the past few days.

From the story at the WXII.com website...

Authorities lifted a curfew and alcohol restrictions in King on Sunday, but said a state of emergency declaration remained in effect until Monday.

Authorities said the state of emergency declaration would continue until Monday 9 a.m., barring any unforeseen circumstances or severe changes.

Effective Sunday afternoon, alcohol restrictions and a curfew were lifted. All other remaining restrictions would continue until Monday, said Paula May, King police chief.

Other restrictions include a ban on the sale or purchase of any type of firearm, ammunition, explosive or any possession of such items off a person's own premises.

King is a rather small town. If people are inclined to own a gun there, they're more likely than not probably already in possession of one.

Just don't understand what the point of this restriction is.
