Tornado warning issued in southern Ontario Wednesday night, rain and storm threat continues Thursday
Thursday, June 12, 2014, 9:15 AM - Rainfall warnings covered parts of Ontario Wednesday as two waves of moisture brought unsettled conditions to the province.
"Showers moved into southwestern Ontario overnight, reaching the Greater Toronto Area by the early morning commute," says Weather Network meteorologist Kelly Sonnenburg.
Much of the region saw a break from the rain through the afternoon and evening hours before a tornado warned thunderstorm pushed through late Wednesday night.
Just after 11 pm, a tornado warning was issued for parts of the region including St. Catharines, Grimsby and northern Niagara region.
"At 11:05 pm EDT, Environment Canada meteorologists are tracking a thunderstorm that is possibly producing a tornado," said Environment Canada in the warning. "The thunderstorm is located just northwest of Fenwick and is tracking northeast at 40 km/h." The warning was dropped shortly after and no tornado touch downs were reported.
Persistent heavy rain however, resulted in some traffic delays early Thursday.

Toronto and Region Conservation issued a flood watch Wednesday morning warning that the rainfall forecast could cause high flows and water levels in Greater Toronto Area creeks and rivers, resulting in unsafe conditions.
"Please exercise caution around all bodies of water," the warning read. "Please alert any children under your care of these dangerous conditions and supervise their activities."
Rainfall warnings remain in place for parts of eastern and northern Ontario Thursday with an additional 20-40 mm of rain possible through Friday.
"Much of the rain will come from thunderstorm activity, as a result, amounts will be quite variable," says Environment Canada in the warning. "Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible."
