At least five people were killed and over 30 civilians and firefighters have reportedly been injured in dozens of wildfires raging throughout Northern California.
The death of a resident in Solano County, in the northeastern San Francisco Bay Area, was reported Thursday by Sheriff Thomas A. Ferrara, although he didn't have any additional details, reports AP.
In addition, three civilians had died in Napa County since the fires began, said Daniel Berlant, a Cal Fire assistant deputy director.
In all, more than 30 civilians and firefighters have been injured.
More than two dozen major fires were scorching California and taxing the state's firefighting capacity, sparked by an unprecedented lightning siege that dropped nearly 11,000 strikes over several days.
The fires have destroyed 175 structures, including homes, and are threatening 50,000 more, said Daniel Berlant, an assistant deputy director with the state Department of Forestry and Fire Protection. In all, 33 civilians and firefighters have been injured.
At least two people were missing.
Smoke and ash billowing from the fires has fouled the air throughout the scenic central coast and San Francisco.
It wasn't immediately clear whether the Solano and Napa county fatalities included a Pacific Gas & Electric utility worker who was found dead Wednesday in a vehicle in the Vacaville area between San Francisco and Sacramento.
A pilot on a water-dropping mission in central California also died Wednesday when his helicopter crashed.
Gov. Gavin Newsom addressed the wildfires, calling them clear evidence of climate change, in a last-minute video recorded for the Democratic National Convention from a forest near Watsonville after he visited an evacuation center.
Most of the activity is in Northern California, where fires have chewed through about 500 square miles (1,250 square kilometers) of brushland, rural areas, canyon country and dense forest surrounding San Francisco.
More than 10,000 firefighters are on the front lines, but fire officials in charge of each of the major fire complexes say they are strapped for resources. Some firefighters were working 72-hour shifts instead of the usual 24 hours. The state has requested 375 engines and crew from other states.
More firefighters were sent to battle a complex of fires in Santa Cruz and San Mateo counties but "it's still not enough," said the incident commander, Cal Fire Assistant Chief Billy See.
Cal Fire spokesman Dan Olson said there are concerns that some people are trying to organize through social media to create volunteer brigades and fight the fire themselves.
In Monterey County along the coast, about 9,000 people have been evacuated for a fire that's now 52 square miles (136 square kilometers).
Two fires in Sonoma County prompted evacuation orders for 8,000 residents near the Russian River Wednesday. Residents of Healdsburg, with a population of about 12,000, were warned Wednesday night to be ready to flee. Fires in that region destroyed more than 100 buildings, including some homes, and threatened 25,000 people across five counties.
Tim Edwards, president of the union representing 7,000 Cal Fire firefighters, said lawmakers need to allocate more money at a time when firefighters are working 40 to 50 days at a time without real relief.
California State Parks announced full or partial closures of more than two dozen parks, including Big Basin Redwoods in the Santa Cruz Mountains, where the park headquarters and other facilities were damaged. The park featuring towering stands of ancient coast redwoods dates to 1902 and is the state's oldest.
