September 29, 2010 — Another low pressure system is set to bring bands of heavy rain to much of eastern Canada Thursday.

It's been a soggy few days for much of eastern Canada.

Throughout the day on Tuesday, people in southern and eastern Ontario were hit with intense bands of rain and noisy thunderstorms. Nearly 47 mm of rain triggered some intense flooding in the city of Hamilton. Sarnia was hit with 43 mm, Bancroft saw 38 mm, and 31.6 mm of rain was recorded at Toronto's Pearson International Airport.

Ontarians faced a drier day on Wednesday, but the same low pressure system continued to soak southern Quebec and the Maritimes.

The most impressive rainfall totals however, come from western Newfoundland where around 90 mm has been recorded over the past couple of days.

“It's a very disorganized area of low pressure that has been bringing widespread rain from the Florida Panhandle to eastern Canada,” explains Michelle Cassar, a meteorologist here at The Weather Network.

Now, yet another low pressure system is set to move in on Thursday.

“A system swirling near Florida will head north over the next 24 hours, bringing drenching rain to the US eastern seaboard, southeastern Ontario and Quebec,” says Gerald Cheng, a meteorologist at The Weather Network. Parts of Quebec could see 50 to 80 mm of rain beginning Thursday morning.

“The Greater Toronto Area will be sandwiched between this system and an incoming cold front, so wet weather and cooler temperatures are expected there,” says Cheng.

If Ottawa receives 20 to 30 mm of rain on Thursday, the city could set a new record for monthly rainfall in September. The previous record of 173 mm was set back in 1945.
