People around Quebec were cleaning up Monday, after tropical storm Irene brought high winds and heavy rains to many parts of the province.

Some roads were closed because of flooding or fallen trees, and about 150,000 households are still without power.

During the storm's peak Sunday night, Hydro-Quebec said nearly 250,000 customers lost power.

One man remains missing after a road washed out and two cars were swept into the Yamaska River near Sorel, northeast of Montreal.

Two other men escaped with minor injuries.

The hole in the road is about 30 metres long and 15 metres deep. Police said it's possible other cars were also washed away, as they are uncertain when the road collapsed.

Provincial police divers searched the river for the missing man throughout the day.

By 7:30 p.m. Monday, police had located two cars.

They could not confirm if either belonged to the missing man. On Monday night, police said they were still working to remove the vehicles from the water.

A section of highway in the Charlevoix region was also washed away.

Two people were reportedly injured when their car fell into a sunken section of road on route 138. The collapse prompted the closure of the highway between Saint-Siméon and Baie-Sainte-Catherine. One lane was reopened to traffic Monday evening.

Homes evacuated

In the Eastern Townships — one of the hardest hit areas — between 100 and 200 mm of rain fell over a 24-hour period, causing flooding in some spots.

Dozens of homes had to be evacuated when a river burst its banks in Cookshire, east of Sherbrooke.

Quebec civil security spokesperson Jean-Thomas Bilodeau-Fortin said there were other evacuations as well.

"Right now we have about 100 houses that are flooded and evacuated in the whole province," he said. "But [it's]

not as bad as we thought it would be."

The storm is continuing its move eastward, exiting the St. Lawrence River valley and heading toward Labrador.
