Wednesday, April 5, 2017, 4:45 PM – Yet another moisture laden low is set to push into southern Ontario and southeastern Québec starting Wednesday night and impact the region through Friday with significant rainfall and some accumulating snow.
Environment Canada has issued a rainfall warning for most of southern Ontario, with 30 to 50 mm expected into Thursday. With this comes the risk of localized flooding as “the ground, already near saturation, has little ability to absorb further rainfall,” according to Environment Canada.
Meanwhile, snowfall warnings have been issued for Algonquin and Burk’s Falls, with 15 to 25 cm possible.
