There's a power interruption at Clinton Public Hospital with the majority of power out.
Officials say patient safety is of paramount importance and staff are assessing the situation and putting a plan of action into place Thursday.
Officials are telling the public not to visit the emergency department at the hospital and instead are asked to attend Alexandra Marine & General Hospital in Goderich or the Seaforth Community Hospital.
Power is expected to be back on by 4 p.m.
