Flash freezing risk in Nova Scotia during Tuesday commute

Today and tonight, a coastal low pressure system will move from Cape Cod and into the southwest of Nova Scotia before moving into the Gulf of St. Lawrence.

The passage of the low will be preceded by snow for many in the Maritimes and a significant mix of ice pellets, freezing rain and rain is expected overnight in Nova Scotia.

There will also be a sharp drop in temperatures early Tuesday morning and that has resulted in flash freeze warnings for much of Nova Scotia.
