Authorities have so far counted 616 structures were destroyed and 183 damaged by the deadly Southern California fire.

The latest numbers issued Friday morning reflect damage assessments in 57% of the burned area.

Containment of the fire has also increased to 78% of the fire zone encompassing 153 square miles (396 square kilometers) of suburbs and wilderness west of Los Angeles.

Firefighters could be helped by onshore flows of moist air from the Pacific, with some gusts up to 20 mph (32 kph) in the afternoon and increased humidity levels.

Firefighters are monitoring unburned islands of vegetation and crews are working to restore utilities.

Repopulation of evacuated areas is continuing but authorities say some areas remain off-limits due to hazards ranging from burned power poles to compromised gas lines and destroyed roadways.

A firefighter assigned to the Woolsey Fire was struck by a private vehicle early Thursday and hospitalized with injuries that are not life-threatening.

Residents who stayed behind in coastal communities cut off by road closures are getting supplies by boat.

Gas, food, baby wipes and horse pellets are among the items brought ashore Tuesday in the Paradise Cove area of Malibu.

Large boats arrived from Redondo Beach, about 25 miles (40 kilometers) to the south. Supplies were unloaded onto smaller boats and even surf boards. Some residents donned wet suits and swam ashore with cases of water and beer.
