Andrea Stockton, staff writer

November 17, 2010 — An intense low pressure system brought heavy rain to southern Ontario Tuesday evening. Now, authorities are keeping a close eye on fast-flowing rivers and streams.

It was a cool, windy and soggy evening in southern Ontario on Tuesday.

A system from the United States swept across the province, bringing heavy rain and gusty winds with it. 30 mm of rain was recorded at the Toronto Island Airport, and 26 mm fell at Pearson International. Kingston was soaked with more than 50 mm, and just over 20 mm fell in Hamilton, Sarnia and Windsor.

Brian Dillon is a meteorologist here at The Weather Network. He says this was a decent drenching for the province, considering the area hasn't had a significant rainfall in about two months.

“September 16 was the last time the GTA had more than 25 mm of rain and it was back on July 23 when more than 30 mm of rain fell.”

The onset of soggy weather has conservation officials on alert. A high water safety bulletin was issued by the Toronto and Region Conservation Tuesday afternoon. Authorities are warning residents to stay away from any rivers or streams as rising water levels could create fast flowing and dangerous conditions.

There's also some concern for flooding in certain communities. Residents are urged to clear their eavestroughs to prevent from any black flow happening.

Public Works crews in Hamilton are keeping a close eye on city streets as well.

“We have over 40 thousand catch basins in the city so when they plug that often results in flooding...So if a homeowner sees that there's leaves or debris on the catch basin in front of their house, it certainly helps us if they go out and clean it off,” says Dan McKinnon with the Public Works department.

The good news is that the rain is tapering across Ontario.

“There will be on and off showers throughout the day, but the bigger story today will be the wind,” says Dayna Vettese, another meteorologist here at The Weather Network. “There will be sustained winds around 40 km/h in Toronto.”
