But by June, the mountains and forests around the Bay Area as well as the Sacramento Valley and nearby foothills are projected to have above-normal fire potential. The areas with above-normal fire potential are expected to expand north to the Oregon border in August. The report also noted that there is a large number of dead and downed trees and plants in the northern Sacramento Valley because of a heavy snowstorm in February that caused extensive damage. That will increase the potential of significant wildfires.
