The City of Greater Sudbury has declared a 'significant weather event' as of 11 a.m.

"All roads and sidewalks maintained by the City are considered in a 'state of repair' until further notice," the city said in a news release.

"This declaration is not necessarily a notice of a reduced level of service or a road closure; it is to notify drivers and pedestrians to use an appropriate level of caution when travelling during this event and avoid unnecessary travel."

As a result, road and sidewalk maintenance may take longer than usual, leisure programs, garbage and recycling pick up may be affected, and transit schedules may be delayed.

Flash Freeze warnings

Temperatures are expected to drop rapidly throughout Wednesday morning with a brief period of freezing rain.

"During the transition from rain to snow, some areas may see a brief period of freezing rain and ice pellets. In addition, snowfall amounts up to 5 cm are expected today," the weather alert said.

"Ponding water, slush, and any falling precipitation will freeze as the temperature drops."

Snow squall warnings

A snow squall warning is in effect for Sault Ste. Marie and St. Joseph Island on Wednesday morning.

The snow squalls are expected to begin Wednesday morning and end Thursday morning, Environment Canada said.

Snowfall of 15 to 25 cm is expected with strong winds gusting 70 to 80 km/h creating reduced visibility.

"Ice pellets and snow will transition to snow squalls this morning with the passage of a strong cold front," the weather alert said.

"Wind will begin to ease late this afternoon or evening. Snow squalls will weaken and move north of the area by early Thursday afternoon."

Travellers are advised to consider postponing trips until conditions improve.
