Conservation authority issues warning

Meanwhile, a water safety warning has been issued by the Upper Thames River Conservation Authority on Wednesday.

The agency said waterways such as the Thames River pose a safety risk because of rain and above-zero temperatures.

No significant flooding is expected, but melting ice and snow are causing runoff.

Officials said everyone should stay off rivers, streams and ponds, and waterway banks, which pose a significant slip hazard.

Flood control measures are in place in Woodstock, St. Marys and London.

Peak water levels are expected Thursday through Friday.
