Fire danger is high across the Bay Area with soaring temperatures expected all week. The scorching heat combined with dried-up vegetation ready to ignite has fire crews throughout the region on alert. Firefighters responded early Monday to a mulch fire at a compost facility in Cordelia, right on the outskirts of Benicia. The blaze caused plumes of smoke and traffic delays during the morning commute along Interstate 680. Crews extinguished the blaze and no injuries were reported. The Solano County Sheriff says the fire was reported about 3:40 a.m. on Goodyear Road about five miles (8 kilometers) northeast of the Valero refinery.
