Fire seasons are based on weather. In the past, they have started as early as April in some areas and continued into December. Authorities have predicted that the biggest threat to Southern California could come in June – the driest month of the year. Early summer weather is prompting the state’s firefighting agency to declare the opening of fire season in 19 California counties. The declaration will be made Monday for counties spreading from Nevada County in the north to San Diego County in the south. “Temperatures are rising, vegetation is drying out and summer weather patterns have begun. There is always a tremendous potential for wildfire in California,” Ruben Grijalva, director of the California Department of Forestry and Fire Protection, said in a statement. June 12 will be the opening of fire season for other counties in the north. Separately, Orange County’s fire authority said it will declare the season open on Wednesday. The CDF declaration means that the agency will increase its fire preparedness. That could include hiring seasonal firefighters, staffing some fire stations around the clock and moving firefighting planes from Sacramento to areas around the state that have high fire danger.
