The severe thunderstorm warning issued for the Windsor region earlier today has ended, but the the bulk of southwestern Ontario remains under a less serious thunderstorm "watch."
Environment Canada said there was a threat parts of the region could have seen between 50-75 millimeters of rain as the storm moved from west to east.
Earlier Wednesday, a severe thunderstorm watch issued for both Chatham and Windsor cautioned high winds, heavy rain and damaging hail could threaten both regions.
Wind gusts could reach as high as 90 km/h with the possibility of pea-to-dime-size hail hitting the bulk of southwestern Ontario.
"Heavy downpours can cause flash floods and water pooling on roads," the watch notice explains. "Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors."
