Around 100 emergency places will be made available in Périgueux, Bergerac and Sarlat providing homeless people a warm place to stay in the fight against the freezing conditions.
Regular patrols will also be undertaken to try and spot people in difficulty and offer support, with drop-in centres also open providing advice, warm drinks and something to eat.
A nationwide telephone number, 115, is also available that is able to provide advice on temporary homing options for those with no where to stay.
The Dordogne authorities have also warned that with the expected negative temperatures, road users should be properly prepared advising people to ensure windscreens are clear and that they drive slowly in poor conditions.
Also around 60 staff are ready to take to the roads with gritting crews prepared and salt stockpiled in depots.
