Police in Kedah state said the body of 64-year-old German Erna Fisher, who went missing Wednesday, was recovered near her home, according to national news agency Bernama.
Fisher was reportedly living in Kedah state with her son and his Malaysian wife.
She was one of only two confirmed fatalities. The other was a 13-year-old boy who drowned Tuesday. Bernama quoted Kedah police as saying that two sisters, aged 13 and eight, were also feared drowned after the motorcycle they were passengers on crashed into a canal.
The New Straits Times said more than 41,000 people have now been taken to relief centres to escape the floods in Perlis, Kedah and Kelantan states.
Rising waters have hit three Malaysian states on the border with Thailand, which has also been seriously affected.
An airport and a major highway have been closed, and train services and water supplies have also been disrupted by Malaysia’s worst floods in five years.
