The Silverado Fire was a wildfire that burned in October and November 2020 in southern Orange County, California northeast of Irvine. The fire started on October 26 around 6:47 AM near Orange County Route S-18 (Santiago Canyon Road) and Silverado Canyon Road, fueled by strong Santa Ana winds gusting up to 80 miles per hour (130 km/h) and low humidity. Orange County Fire Authority Chief Brian Fennessy stated, "The winds were extraordinary even by Santa Ana standards. Fire spread is exceeding more than anything I've seen in my 44 years." The fire initially moved south from Loma Ridge toward the Orchard Hills, Northwood and Portola Springs communities of Irvine before moving southeast through Limestone Canyon and toward the communities of Foothill Ranch and Lake Forest. The fire burned in a path similar to that taken by the 2007 Santiago Fire, mostly through terrain that had not seen significant burning in the 13 years since that fire. 100% containment was announced on November 7, 2020. The cause of the fire remains under investigation. Southern California Edison officials stated in a letter to the California Public Utilities Commission that they suspect a "lashing wire" in one of their telecommunication lines may have caused the fire.
