The National Weather Service has declared a Red Flag Warning for Orange County and the Inland Empire tomorrow.
That means increased fire danger for the region.
The Red Flag Warning from 6 a.m. to 6 p.m. Saturday covers Orange, Riverside and San Bernardino counties, including the Santa Ana Mountains, foothills and Cleveland National Forest.
Forecasters say moderate Santa Ana winds will buffet the region, but it won't be quite as gusty as last Thursday. Still, they predict the winds will gust up to 35 to 55 mph, especially in the mountains and passes.
Forecasters say it will be warm and relative humidity levels will drop to between 5 and 12 percent. The amount of moisture in vegetation is also expected to drop. The National Weather Service says that could mean "explosive fire growth" if a fire gets going.
The Irvine Ranch Conservancy has called in its fire watch volunteers for the day to keep a closer eye out for any wildfires.
