The cold weather has blown in and Eastern and Northern Lambton County is seeing some snowsqualls and that has caused at least one serious accident on Highway 402 which has closed a stretch of the highway.
Environment Canada says lake effect flurries and local snow squalls have developed in a northwest flow off Lake Huron. The squalls are more intense over the near shore areas south of Goderich towards Grand Bend and into portions of Eastern Lambton County. The snow squalls are expected to shift northward to affect the London area later today or this evening.
The squalls are causing problems on the road. EMS is on the scene of a serious multi car accident on Highway 402 near Watford. Four ambulances were dispatched to the scene and there are reports of at least two serious injuries. The OPP has closed the 402 from Lambton at Forest Road to Highway 401. They’re telling drivers to avoid the area.
Snow squalls cause weather conditions to vary considerably, changes from clear skies to heavy snow within just a few kilometres are common. Be prepared to adjust your driving with changing road conditions. Consider postponing non-essential travel until conditions improve.
Environment Canada says a period of very cold wind chills is expected. A strong cold front is crossing southern Ontario and is ushering in much colder temperatures and gusty north winds. Wind chill values this afternoon are generally expected to be between minus 20 and minus 30 across most of southern Ontario. Tonight will be very cold across all of southern Ontario. Although the winds will diminish somewhat, wind chills of minus 30 to minus 35 are expected overnight and into Friday morning.
