Residents living near Calgary have been placed on notice after tributaries of the Bow River surged with as much as 70 millimetres of rain over the weekend.

Flood watches were in effect in several soggy communities, including Ghost River, Jumpingpound Creek and Waiparous Creek.

Many main roads swelled with water, forcing motorists to drive through flooded parking lots to find alternate routes.

The deluge of rain across southern Alberta is breaking decades-old precipitation records.

Springbank, northwest of Calgary, recorded a whopping 38 millimetres of rainfall over an 18-hour period by 6 p.m. Sunday night, Environment Canada reported.

The total beat the previous 110-year-old record of 29.5 millimetres set back in 1897.

Environment Canada said 27 millimetres of rain fell during the same time frame at Calgary International Airport, coming up short of the 29.5 millimetres recorded in June 17, 1897.

Calgary has already seen 149.2 millimetres of rain so far this June, which is normally the city's wettest month.

"The normal for the entire month is 79.8 millimetres, so they've had in total about 88 per cent rain more rain than they would normally get," Environment Canada senior climatologist David Phillips told CTV.ca.

"It's been almost a degree colder, with almost twice the rain -- I mean talk about depression."

Phillips says the record for rainfall in a month was 247.6 millimetres in June 2005. He said 10 per cent of the city's homes were flooded as a result.

While Calgary still has 12 days to surpass the record, Phillips says Alberta will see beautiful weather the rest of the week.

The forecast calls for a chance of showers in Calgary on Monday and Tuesday, but temperatures will be in the mid-20s all week with plenty of sunshine.

There were no reports of injuries or heavy damage due to flooding, but a violent lightning storm at a park 80 kilometres southwest of Edmonton killed a man and his wife's unborn baby.

Five other people were injured in the Saturday incident at Pigeon Lake Provincial Park.
