The warning, issued at 4:32 a.m. Atlantic time on Sunday, March 19, says that ice build-up due to freezing rain is expected. A low-pressure system over the eastern seaboard will track slowly northeastward toward the Maritimes tonight.
“This system will spread wintry conditions over Nova Scotia this afternoon and evening,” the warning states.
The snow will change to a mixture of ice pellets and freezing rain overnight and then to rain on Monday morning, March 20. Freezing rain will persist the longest over central and eastern portions of the province. Snow and ice pellet amounts ranging from 5 to 15 cm will be followed by several hours of freezing rain early Monday.
“Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous,” the warning states.
Freezing rain warnings are issued when rain falling in sub-zero temperatures creates ice build up and icy surfaces.
