As some people return to what's left of their homes after the Los Angeles-area wildfires, experts are warning about possible dangers of the ash that's left behind.

A weekend weather system could hamper firefighters’ efforts in Northern California to battle the week-old blaze that’s become the largest in the state so far this year.

Firefighters again prevented flames from entering a Northern California mountain town and reported major progress against the week-old blaze that’s become the largest in the state so far this year.

Five of the 10 largest wildfires in state history have occurred since August. Beyond their size, how do the scope and devastation of this year's fires compare to previous wildfire seasons in California? The previous record was set in 2018 when deadly wildfires destroyed 1.67 million acres (2,609 square miles or 6,760 square kilometers). The August Complex, burning in the Coast Range between San Francisco and the Oregon border, surpassed 1 million acres, another record. Gavin Newsom said the amount of land scorched by the August Complex is larger than all the recorded fires in California between 1932 and 1999.

Deadly wildfires in California have burned more than 4 million acres (6,250 square miles) this year more than double the previous record for the most land burned in a single year in the state. California fire officials said the state hit the astonishing milestone Sunday, Oct. 4, 2020 with about two months remaining in the fire season. “And that number will grow.”So far, in this year’s historic fire season, more than 8,200 California wildfires have killed 31 people and scorched “well over 4 million acres in California” or 6,250 square miles, Cal Fire said Sunday in a statement. The astonishing figure is more than double the 2018 record of 1.67 million burned acres (2,609 square miles) in California. Flannigan, the fire scientist, estimates the area of land burned from wildfires in California has increased fivefold since the 1970s.

CNN Video(CNN) - As wildfires swept across California, President Donald Trump took to Twitter Sunday to criticize the state's Democratic governor, Gavin Newsom, for the way his administration has handled the crises.

Must also do burns and cut fire stoppers...."Facts First: The recent fires in Southern California did not originate in forests, so blaming bad "forest management" misses the point. The President previously blamed poor forest management for California fires in 2018, shortly before he met then Lt. Gov. Trump has received criticism for casting sole blame on the state's forest management practices, since the federal government manages over half of California's forest land.
