The family of a woman who died in a landslip in Cornwall have said it was a 'potentially avoidable tragedy'. The home of 68 year old Susan Norman from Looe collapsed following torrential rain on Friday.
Her family say the property's safety had been a concern of Susan's for some time and that contractors had been working on the property to support the retaining wall. The house is due to be demolished today.
The weather has been causing major problems across the region, with many parts of Cornwall and Devon badly affected.
At the moment, the Environment Agency has 12 flood warnings and 44 flood alerts in place for the South West.
Some businesses hit by the rain overnight are still clearing up after the floods earlier this Winter.

Police searching for missing woman Susan Norman have found a body in her partially collapsed house in Looe.
The 68-year-old had not been seen since 6.50pm yesterday evening.
The body has not been identified or recovered at this time.
The overnight rain caused problems across Cornwall and Devon for drivers, residents and business owners.

The police have closed all roads to the school and therefore in order to keep everyone safe school is closed today.
The highways agency will be out to work on the road over the next few days and we currently expect to be open on Monday.
