On May 29, 10 centimetres of rain fell in an hour on the small border town of Emerson. By the end of the day, more than 15 cm had come down. With the ground already saturated, the rain had nowhere to go, flooding most of the basements in town.
“It varied from home to home, but some had as much as [1 to 1.2 metres] in their basements,” said Jeanette Sabourin, town administrator.
A power failure affected part of the town as well, disabling any sump pumps. The mayor declared a state of emergency for the town.
