CAL FIRE reported Sunday morning, Sept. 3, that more than 12,000 firefighters are battling 19 large wildfires in California.

A strong high pressure is forecast to continue to be over the state’s northern region today, with temperatures as much as 20 degrees above normal throughout the region.

Afternoon relative humidity will be 5 to 15%, with recovery only to 20 to 30% at night in many areas. The stable conditions under the strong high will also lead to poor smoke dispersion and poor air quality in canyons and valleys near and downwind of active fires, according to CAL FIRE.

CAL FIRE notes that embers from a wildfire can travel up to a mile away from the main fire and ignite a new fire. It encourages a visit to the ReadyForWildfire.org website to learn more about being prepared for wildfires.
