The Edmonton region received more rain this past weekend than the area typically gets in the entire month of June — and more precipitation is in the forecast.
On average, Edmonton receives 69.9 mm of rain in June. As of early Monday morning, Environment Canada had recorded 95 mm of rain in the core of the city and 73 mm out at the Edmonton International Airport, after the rain began falling Saturday.
It’s been a wet month: so far this June, Edmonton has recorded 189 mm of rain — the most in more than 60 years.
The city is now tied with tied with 1965 for second-wettest June on record — and is expecting to surpass it before month’s end, as more rain is expected next weekend.
The June rainfall record is held by 1914, when 216.5 mm of rain was recorded in the city.

Global NewsNorth Saskatchewan River flowing high, fast
The North Saskatchewan River is flowing high and fast after a weekend of relentless heavy rain.
As of noon, the river was flowing around 1,050 m³/s through Edmonton — about double the speed recorded 48 hours earlier. The river also rose about 1.5 metres over that time period.
Water levels may rise an additional 0.5 m before the river peaks late Monday or early Tuesday, Alberta Environment said in its advisory Monday afternoon.
A high streamflow advisory is in effect for the North Saskatchewan River and its tributaries between Rocky Mountain House and the Saskatchewan border.
Alberta Environment said water level increases of one to 1.5 metres are possible at various points along the North Saskatchewan, but as of Monday afternoon no river-related flooding was expected at this time.
Plenty of debris is being caught up in the strong current and high waters, including an entire dock with several boats still attached.

Supplied to Global NewsEmergency alerts as stormwater systems overwhelmed
The deluge on Saturday and Sunday forced several municipalities in the region, including the City of Edmonton, to issue emergency alerts as the heavy rainfall has pushed the region’s stormwater system to the brink.
Edmonton Mayor Andrew Knack is holding a news conference Monday afternoon to answer questions about the city’s water supply and the ongoing response to the heavy rainfall event.
“Thank you to everyone who has delayed laundry, shortened showers, reduced water use and taken other steps to help,” Knack said.
‘These actions matter, and help reduce the strain on the system at a critical time. I would also like to thank all the crews that have worked diligently over the weekend to ensure Edmontonians safety.”
Utilities provider Epcor said Monday with more rain in the forecast for the Edmonton area, the stormwater system remains under pressure.
It says it received more than 600 calls about flooding, adding that it continues to respond on priorities including public safety.
“It’s insane right now,” said Edmonton resident David Howard. “I saw pump trucks all over the city, just pumping water out of the sewers.”
Epcor said a rainfall event of this nature requires all kinds of equipment and with the amount received this weekend, pumps have been used to move stormwater to other parts of the system to balance capacity.
Epcor also said Monday that residents living near stormwater ponds should keep a distance as water levels continue to rise.
“These ponds are doing their most important job right now, collecting excess rainwater, slowing its entry into the system and improving the quality of water that will eventually enter the North Saskatchewan River,” Epcor said.

Global NewsThe emergency alert, issued Sunday evening, was one of seven to be sent out for areas near the city due to heavy rainfall over the past 24 hours.
That precipitation has pushed the region’s stormwater system to capacity, with localized flooding and backups being reported in neighbouring communities, the Alberta Emergency Alert said.
“If the stormwater system continues to operate over-capacity, flooding and sewer backups will continue to increase,” it added.
Authorities are advising residents to avoid unnecessary indoor water use, limit showers and baths, delay laundry and dishwasher use and ensure sump pumps and downspouts are functioning properly to direct water away from homes.
It’s unclear how long the alert will be in place for.
Other communities that issued alerts included Beaumont, Stony Plain, Tofield, Wabamun and parts of Lac Ste. Anne County.
St. Albert also issued an alert that was dropped Monday afternoon as their system had stabilized.
