The East Coast is bracing for an impactful and typical winter storm, potentially a nor'easter, for the start of next week.

This system is so potent that it could even bring snow to portions of Florida and Georgia. A swath of 10-20+ cm of snow will likely accompany this system as cold air is present to the north.

But precipitation types and amounts will depend on the ultimate track of the system this system takes as it moves up the East Coast.

Snow accumulations may make travel hazardous. Roads and walkways could become slippery and difficult to navigate. Consider adjusting plans to avoid the most adverse conditions.

All the ingredients are coming together for a potentially impactful storm for much of the region. Nor’easter is set to develop Sunday evening off the northeastern U.S., then track towards Atlantic Canada overnight into Monday.
