Snow squall warning replaces snow squall watch for:
Parry Sound – Muskoka,
Haliburton,
Current details:
Multi-day lake effect snow squall event to begin this evening.
Hazards:
Locally heavy snowfall with accumulations possibly exceeding 30 cm by Friday night.
Peak snowfall rates of 5 to 10 cm per hour.
Very poor visibility in bursts of heavy snow and local blowing snow.
Isolated power outages due to the expected heavy wet nature of the snow.
Timing:
Beginning this evening and ending Sunday morning.
Discussion:
Lake effect snow off Lake Huron and Georgian Bay is forecast to strengthen this evening into Friday morning and will persist until Sunday morning.
Latest analysis indicates that a very intense band of lake effect snow will affect portions of the area during the day Friday. This band may extend well inland towards Haliburton and produce high snowfall rates. The band should shift south of the regions Friday night but is expected to move back north into the area on Saturday.
As is common with lake effect snow, snowfall amounts will be highly variable. Some areas may receive well in excess of 50 cm by Sunday.
Road closures are possible, especially over areas that receive multiple lake effect bands.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel is expected to be extremely hazardous due to reduced visibility. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.
