KAHULUI: Recovery crews in Hawaii are likely to find between 10 and 20 more victims per day, the state's governor has said -- meaning the toll from the deadliest US wildfire in a century is expected to rise sharply.

At least 96 people are already confirmed to have died, but Governor Josh Green said emergency responders with cadaver dogs will need more than a week to work their way through hundreds of homes and burned-out vehicles in hard-hit Lahaina.

"There are more fatalities that will come," he told CBS in an interview aired Monday.

He added: "They will find 10 to 20 people per day probably until they finish. And it's probably going to take 10 days. It's impossible to guess, really."

Hawaii fire death toll nears 100, and anger grows

The historic coastal town of Lahaina on the island of Maui was almost destroyed by the fast-moving inferno last week, with survivors saying there had been no warnings.

With some cell phone communications now restored, residents have been able to connect with family and friends, and the number of people still missing has been reduced from more than 2,000 to around 1,300, said Green.

"Our hearts will break beyond repair, perhaps, if that means that many more dead. None of us think that, but we are prepared for many tragic stories," he said.

The town, which served as the Hawaiian kingdom's capital in the early 19th century, was home to around 12,000 residents.

More than 2,200 buildings were damaged or destroyed as the fire tore through Lahaina, according to official estimates, wreaking $5.5 billion in damage and leaving thousands homeless.
