The floods submerged multiple vehicles, and Royal Canadian Mounted Police spokeswoman Cindy Bayers said two such incidents in West Hants north of Halifax have left two adults and two children unaccounted for as of Saturday morning.
The two children went missing after the vehicle they were travelling in got stuck underwater, Bayers said, noting the three other occupants were able to escape safely.
Two other individuals, who Bayers described as a youth and a man, remain unaccounted for following a separate vehicle submersion. Two other people in that vehicle were rescued, she said, adding police are actively searching for all four missing people.
Torrential downpours started on Friday afternoon across the Halifax region, dumping more than 200 millimeters of rain in some areas. The port city typically receives about 90-100 mm of rain during an average July.
Based on radar estimates and unofficial observations, Environment Canada said on Saturday that some areas may have received more than 300 mm in 24 hours. Radar maps show the heaviest rainfall extending along the province’s southwestern shore to a point north of Halifax.
Widespread flooding has also been reported in Lunenberg County, which is west of the Halifax region.
On Friday night, water levels rose so fast in the Bedford area that volunteers with Halifax Search and Rescue were using small boats to rescue people from inundated homes.
In the Hammonds Plains area, northwest of the city, flooding washed out driveways and the shoulders of many roads.
That’s the same area where where 151 homes and businesses were destroyed by a wildfire that started on May 28, forcing evacuations that affected 16,000 residents. And for much of the past week, the Halifax area has been sweltering under an immobile dome of humidity — a rare event so close to the coast.
It was only last fall that post-tropical storm Fiona descended on the Atlantic region, killing three people, flattening scores of homes and knocking out power to more than 600,000 homes and businesses. Fiona was the most costly weather event in the region’s history, causing more than 800 million Canadian dollars ($604 million) in insured damage.
“It’s pretty obvious that the climate is changing — from Fiona last year to the wildfires in the spring and now flooding in the summer,” Halifax Mayor Mike Savage said.
“We’re getting storms that used to be considered one-in-50-year events ... pretty regularly,” he added.
While the official statistics have yet to be recorded, it’s believed the Halifax region has not seen this level of rainfall since Aug. 16, 1971, when hurricane Beth made landfall near the eastern tip of mainland Nova Scotia and then roared over Cape Breton. At that time, almost 250 mm of rain fell on the Halifax area, causing widespread flooding and damage.
