Location of Northern California wildfires

2017 California wildfires from January 1 to October 11

Copernicus Sentinel-3A satellite picture, October 9.

The October 2017 Northern California wildfires are a series of wildfires that are burning across the state of California, United States. They broke out throughout Napa, Lake, Sonoma, Mendocino, Butte, and Solano counties during severe fire weather conditions effectively leading to a major red flag warning from much of the Northern California area. Seventeen separate wildfires were reported during this time.

Due to the extreme conditions, shortly after the fires ignited, they rapidly grew to become massive full scale incidents spanning from 1,000 acres (400 hectares) to well over 20,000 acres (8,100 ha) each within a single day. By October 12, 191,437 acres (77,472 ha) in California were burning, and an estimated 3500 structures were destroyed. In addition, the Northern California fires have killed at least 23 people and hospitalized at least 100.

Weather

Days prior to the wildfires, the California Department of Forestry and Fire Protection (CAL FIRE) had begun issuing red flag warnings throughout much of the northern California as conditions were expected to become extremely volatile, with winds expected to be gusting between 25 to 35 miles per hour (40 to 56 km/h) from the north to the south. By the evening of October 8, the Diablo winds were reported gusting up to 70 miles per hour (110 km/h) within the affected areas as over a dozen wildfires began to break out.

By October 12, the air quality in the city of Napa was ranked the poorest in the nation, due to high levels of particulates and ozone. Smoke from the wildfires had spread nearly 100 miles since October 8, with "unhealthy" air quality indices registered in the cities of Oakland, San Francisco, and San Rafael.

Disaster declaration

On October 9, 2017, California governor Jerry Brown declared a state of emergency for the counties of Napa, Sonoma, Yuba, Butte, Lake, Mendocino, Nevada, and Orange, and sent a letter to the White House requesting a major disaster declaration. President Donald Trump approved the disaster declaration on October 10. That evening, Brown issued an emergency declaration for Solano County as well. Surveying the region, representative Mike Thompson of California's 5th Congressional District stated "I fully expect this will be the worst fire disaster in California history."
