Heavy rains caused flooding in southern Norway Monday, forcing many residents to leave their homes.

Floods ripped through the northern tip of Randsfjord in southern Norway, Aftenposten reports.

Several homes were destroyed or severely damaged and cars were swept away after the heavy rains caused a dam to break, sending torrents of water rushing down the Nordraak River.

The broken dam resulted in landslides that ended up plugging the river, causing more flooding.

Authorities declared Randsfjord a disaster area.

Weather forecasters said more rain was expected Wednesday.

This summer has been southern Norway's wettest on record.
