It was a dark and stormy afternoon and evening in Chatham-Kent.

Hydro One crews are working to restore power this morning.

Some areas, including Ridgetown and Blenheim, are believed to have received over 100 mm of rain over the course of the day, prompting a flood watch from the Lower Thames Valley Conservation Authority.

Officials expected to operate the McGregor Creek Diversion channel overnight to keep fast-rising water away from downtown Chatham.

The storm, which also brought high winds and hail, took down hydro lines, tree branches, and sign posts in some areas.

Hydro One crews continue to work on a few scattered power outages this morning, mainly in the Thamesville and Kent Bridge areas.
