The cold means that Sara Andersson will leave Ruhpolding on Thursday or Friday.
"She is isolated from the rest of the team and will probably travel home today or tomorrow," writes national team coach Johannes Lukas in a message.
Andersson took gold and bronze in the JVM last year and would get the chance to drive in the World Cup for the first time this week in Germany.
Nor will Linn Persson start in the distance race which is broadcast on SVT starting at 13.55.
