LEGE-CAP FERRET, France (AP) — French authorities gave the go-ahead Thursday for 84,000 evacuees forced out by a monster wildfire to go back to their homes in southwest France, the strongest sign yet that firefighters are turning a corner in their battle against the flames that have burned an area four times the size of Paris.The authorized returns announced Thursday covered nine localities that had been evacuated. In all, more than 220,000 people were forced to flee their homes since last week.Higher humidity, cooler temperatures and slight rain raised hopes that Thursday could be a decisive step on the way to vanquishing the fire.Local officials reported a “rather calm” night, with a fire that has not grown beyond the 42,000 hectares (about 162 sq. miles) already affected. Fire crews remained at “total mobilization” with 2,200 firefighters and over 20 aircraft.

Rain fell early Thursday in the city of Bordeaux to the east. Sophie Brocas, the prefect for the Gironde region, expressed some optimism that lower temperatures could help. “If that’s confirmed, we could foresee a return to a more normal life for residents, but also for businesses that need to work,” she told reporters late Wednesday.Humidity reached 80% overnight but was expected to drop by midday, authorities said. Some rainfall was expected along the coast that “could reach the fire zone,” Gironde officials said in a morning note.
