Heavy winds and rain in the central and south Chilean lowlands affected 26,000 people. Ten of the victims were killed in a landslide in the Biobio region 600 kilometres south of Santiago.
The rain has stopped after a two day downpour allowing officials to distribute aid and inhabitants to begin rebuilding houses as the storm moved into the Andes mountains toward Argentina.
President Michelle Bachelet travelled to the devastated region yesterday to personally deliver her condolences to those hit by the storm.
She went to discuss additional aid for the region which has been declared a disaster zone.
Meanwhile pelting winds and snow jammed traffic around the crucial 3,200 metre-high Christ the Redeemer pass and tunnel that links Mendoza in western Argentina with Santiago.
Route 7 was blocked by an avalanche of mud and rock on the Chilean side of the border to aggravate the situation.
