Severe storms Sunday knocked out power to thousands of people and snarled public transit in the Chicago area.

The Chicago Transit Authority said service along parts of three train lines was temporarily suspended Sunday evening.

CTA spokeswoman Catherine Hosinski says a pedestrian ramp canopy damaged by lightning, wind or a combination of the two caused an obstruction along the Blue Line.

There were no immediate reports of injuries.

Service on the Brown and Red lines was also impacted by storm debris.

Hosinski says the CTA is working toward having normal operations in place before the morning rush.

ComEd reported Sunday evening about 24,000 customers are without power in Cook County.
