The ongoing heatwave conditions in the north of France have led officials to raise the warning level in 14 departments to a tier-three orange level.

The warnings will come into place overnight between Thursday (September 7) and Friday (September 8).

The departments facing the elevated warnings are: Cher, Eure-et-Loir, Indre, Indre-et-Loire, Loir-et-Cher, Loiret, Paris, Seine-et-Marne, Yvelines, Essonne, Hauts-de-Seine, Seine-St-Denis, Val-de-Marne and Val-D'Oise.

Those in the affected departments should make sure they remain cool throughout the day, and keep up to date with local weather information and advice.

Alongside these, 37 departments – largely in the west and north of France – remain at a tier-two orange level.

The current heatwave – which started on Monday – has broken hundreds of September heat records in the country, as well as recording the hottest ever September day in France’s history.

Unlike August’s record-breaking heatwave, it is primarily affecting the north and centre of France, as well as parts of the western coastline.

Forecasters are still expecting temperatures to remain around current levels until at least Sunday, after which they should begin to drop.
