Lambton County has declared a significant weather event.

It was put in place as of 9 a.m. Saturday, due to current and forecasted weather.

This comes after Highway 402 is completely closed, as well as other roads in the county.

Drivers are reminded to use extreme caution when travelling. It could take longer to bring roads back to normal conditions, the county said.

In response, the Emergency Operations Centre has been activated as well. Warming centres are open for anyone who needs somewhere safe and warm to go. A full list is available here. All Lambton County Library locations are closed.

“Lambton Emergency Medical Services is experiencing prolonged response delays in the Plymptom-Wyoming and Lambton Shores areas,” the county said.

“Residents are asked to call 911 only for life-threatening emergencies at this time. For non-urgent medical concerns, residents are encouraged to contact Health Connect Ontario at 811 or online.”

Lambton EMS will continue at normal service when it’s safe to do so.

“Public safety is our top priority,” said Deputy Warden Jeff Agar.

“We are asking residents to take this situation seriously, avoid unnecessary travel, and follow all road closures and safety advisories. These measures help protect both the public and the emergency responders working in challenging conditions.”
