(MercuryNews) - Here are six things to know Friday morning as firefighters enter their sixth day battling several wildfires in Northern California.

1.) Friday morning, Napa police delivered some good news to their residents: Overnight, many people were allowed to return to their homes. At 5 p.m. Thursday, the Napa County Sheriff’s Office announced a mandatory evacuation order has been lifted for areas of the Silverado Country Club, Monticello Park and The Avenues.

2.) Thursday night, the death toll of the wildfires burning in Northern California hit 31, becoming the deadliest in the state’s history. There are still about 400 people missing in Sonoma County, and officials fear the number of deaths may continue to grow. Late Thursday, Sonoma County authorities released the names of ten of the dead.
