June 30, 2008 -- A "red flag warning"—meaning the most extreme fire danger—was still in effect for Northern California until 8 a.m. EDT Monday. And the coming days and months are expected to bring little relief.  Some 364,600 acres—or almost 570 square miles—have burned.  Lower-than-average rainfall and record levels of parched vegetation likely mean a long, fiery summer throughout northern California, according to the Forest Service's state fire outlook released last week.  The fires burning now were mostly sparked by lightning storms that were unusually intense for so early in the season. But summer storms would probably be even fiercer, according to the Forest Service.  "Our most widespread and/or critical lightning events often occur in late July or August, and we have no reason to deviate from that," the agency's report said.  The blazes have destroyed more than 50 buildings, said Gregory Renick, state emergency services spokesman. More than 19,500 firefighters are battling the blazes and 926 helicopters have been used.  A wildfire in the Los Padres National Forest has forced the closure of a scenic stretch of a coastal highway and driven away visitors at the peak of the tourist season.  Air quality districts from Bakersfield to Redding issued health advisories through the weekend, urging residents to stay indoors to limit exposure to the smoky air.  On Saturday, President Bush issued an emergency declaration for California and ordered federal agencies to assist in firefighting efforts.  But California emergency officials said state and local governments would also need federal financing to cover the costs of fighting so many fires this early in the year.  Federal aid now includes four Marine Corps helicopters, remote sensing of the fires by NASA, federal firefighters, and the activation of the Federal Emergency Management Agency.
