California wildfires burn 4 Million hectares and leave 31 people dead during the record breaking season

The flames burned an area larger than Connecticut, and firefighters in a fire in the Wine Country north of San Francisco were on alert on Friday when the weather forecast warned of extreme fire danger until Saturday.

Deputy Fire Chief Jonathan Cox said 3.98 million acres have been burned by forest fires in California since August 15.

"We should not underestimate the fact that we have burned an unprecedented number of acres across the state. And, unfortunately, we are entering some of the most critical months of fires in California". 

Strong winds did not appear early Friday morning, so firefighters had a chance to win something, but wind speeds of up to 30 miles per hour were predicted, which would sweep the hills of Napa and Sonoma counties, while the glass fire, which exploded on a massive scale earlier this week, threatened more than 28,000 homes and other buildings.

The wind was blowing on the west side of the fire at a higher altitude, and crews were expecting a long battle to prevent the flames from jumping over the containment lines and to prevent the fires from jumping forward and setting new fires.

The glass fire is the fourth major fire in the region in three years and is approaching the third anniversary of a fire on October 8, 2017, which killed 22 people.

The death toll has risen to 31 people after a person burned in the LNU flash fire complex died from their injuries, Cal Fire said in a statement.

A group of fires started in mid-August in San Francisco Bay after the lightning strike was completely contained on Thursday.

Since the fire broke out on Sunday, the fire has destroyed nearly 600 buildings, including 220 homes and almost the same number of commercial buildings.

About 150 miles north of wine country, the Zogg fire, which also broke out during Sunday's strong winds and grew rapidly, killed four people and destroyed 153 buildings.
