As the tornado crossed Interstate 215, a semi-truck was lifted 30 to 40 feet into the air and nine empty BNSF railroad cars were derailed. The driver of the semi had to be extricated using the ???jaws of life??? and was hospitalized for over a month due to moderate head injuries. The tornado also damaged the roofs of several homes and a trailer on Kuder Ave. It should be noted that another tornado developed nearby while this tornado was in progress. Based on input from Dr. Kisho Mehta and Tim Marshall, damage to the rail cars was consistent with wind gusts up to 120 mph, or an EF-2 tornado. This is the first EF-2 tornado in California since the new scale was implemented in February 2007, and the first F2 tornado in California since the 1998 Sunnyvale tornado. EPISODE NARRATIVE: A thunderstorm developed near Redlands around 3:30 PM and quickly became severe as it moved south-southwest toward Moreno Valley along the Elsinore Convergence Zone. This storm produced large swaths of hail, flash flooding, and at least four tornadoes. | |||||||||||
