South Carolina braced for the arrival of a massive winter storm system – dubbed “Leon” – on Tuesday, shutting down its government, schools and businesses in anticipation of the Arctic invasion.

And while kids dreamt of frolicking in powdery white snow, utility crews prepared for a nasty winter mix of precipitation that could result in widespread power outages due to iced over limbs and weighed down power lines. No one is quite sure how much snow and ice this system will dump on the Palmetto State (or where that precipitation will fall), but there is┬áparticular concern regarding the Lowcountry – which is expected to see more ice than snow.

“There appears to be an enhanced threat of damaging heavy accumulations of ice around Savannah, Ga., and Charleston, S.C.,” The Weather Channel reports. “This will bring the potential for extensive and long-duration power outages. Falling trees and heavy ice accumulations could cause widespread road closures and make travel nearly impossible by Tuesday night.”

Meanwhile the Midlands region of the state is projected to receive anywhere between 3-5 inches of snow – which would be the most it has seen since a 2010 storm dumped 8.5 inches.

The Upstate is projected to receive between 1-3 inches of snow.

The National Weather Service has placed almost the entire state of South Carolina under a winter storm warning through Wednesday morning at 9:00 a.m.

“Only travel if it is absolutely necessary,” the warning states.
