SACRAMENTO, Calif. - SACRAMENTO, Calif. - Hundreds of lightning-sparked wildfires have turned the air of Northern California into an unhealthy stew of smoke and ash, forcing the cancellation of athletic events and other outdoor activities.
Health advisories urging residents to stay indoors to limit exposure to the smoky air were issued Saturday from Bakersfield north to Redding, a distance of nearly 450 miles.
Air pollution readings in the region are two to 10 times the federal standard for clean air, said Dimitri Stanich, spokesman for the California Air Resources Board.

Some areas are experiencing the worst air quality on record, with the smoke hanging to the ground like a fog.

Air quality agencies are especially concerned about small-particle pollution. The tiniest particles can penetrate the body's immune defenses, traveling deep into the lungs and the bloodstream.

"When you have it on the scale we are seeing now, it is very dangerous to the general public health," Stanich said. "This is a very serious problem."

Changing weather brought smoke-clearing breezes and brief relief to some areas Saturday, but it could bring lightning storms similar to the ones that ignited fires across Northern California a week ago.

The thunderstorms could also bring a small amount of much-needed rain, he said. The front was expected to pass today, setting up another week of abysmal air quality.

The renewed threat of dry lightning and stiffer breezes that could stir the wildfires led fire officials to declare a "red flag warning" - meaning the most extreme fire danger - until 5 a.m. Monday for Northern California.
