The Windsor area looks set to be spared from heavy rain on Wednesday as remnants of Hurricane Beryl move across southwestern Ontario.

As of 8 a.m. ET, the low pressure area is expected to pass south of Windsor-Essex later this morning and into the afternoon.

“The wind will continue to drift along Lake Erie for the rest of the day,” said Geoff Coulson, a meteorologist with Environment Canada.

“There will be more rain around it. But we will see the rain taper off into more scattered showers tonight.”

Coulson says Windsor has had about 30mm of rain so far since the showers started last night, but more is on the way.

“Rain has stopped for a while in far southwestern Ontario in and around the Windsor area over the past few hours, but more rain is coming soon to southern Michigan and northern Indiana, and will continue through the rest of the day.”

Environment Canada reported Tuesday that record rainfall is expected in parts of the region on July 10.

Coulson expects the heaviest rainfall in the region to occur just northeast of Windsor.

“Parts of Sarnia, Lambton County and into London and Middlesex County. Even areas further east could also see significant rainfall.

The Essex County emergency response coordinator said he has heard reports of minor flooding and standing water in a few areas of Lakeshore, but overall the county has not experienced any major damage or water backups, he added.

“The remnants of Beryl moved north, especially over our area. I suspect Sarnia and Michigan got more rain as the storm moved around. And now Niagara and Toronto will probably get more rain than we do before the storm passes,” said Dan Metcalfe.

“I think we’ve had the worst of it yet and it will clear up on Thursday, but you know Mother Nature is unpredictable sometimes.”

Tian Martin of the Essex Region Conservation Authority said their rain gauges are showing 30 to 40 millimeters across the city and region, with the highest amounts in LaSalle and Tecumseh.

She said there have been no reports of flooding in the region yet and she attributed this to low ground saturation due to the recent heat.

A rainfall advisory remains in effect for the region from Environment Canada, with some areas expected to receive as much as 60 millimetres.

The wildlife authority for parts of Sarnia-Lambton and Chatham-Kent reports that between 30 and 40 millimetres of rain had fallen as of 10 a.m. ET, with the heaviest rainfall along the shores of Lake Huron.

Nicholas Hagerty is a water technician with the St. Clair Region Conservation Authority (SCRCA).

He said 12 stream meters are being used to collect data in communities including Sarnia, Wallaceburg, Dresden, Petrolia, Alvinston and Florence.

“The stream data gives us real-time data on flows and conditions. And most of them have tipping buckets, so we can collect rainfall data as well,” he said.

According to Hagerty, not enough rain has fallen in a short period of time to meet the criteria for issuing a flood warning.

“Not at the moment. The forecast for the next 24 hours is five to ten millimeters, so that could change. I’m constantly checking the current conditions. What are the current meters telling me? How is the watershed responding?”
