The damage path was around 200 yards wide and was rated F1 in intensity. As it traveled northeast, it snapped, uprooted and twisted numerous trees and caused minor roof damage to a manufactured home. As the tornado crossed Highway 49, two and a half miles north of the town of Black, it caused considerable damage. Numerous trees were snapped and uprooted, an unanchored manufactured home sustained heavy damage and was shifted 30 feet. Two automobiles were lifted distances ranging from 10 to 50 yards and two other homes sustained varying degrees of damage directly from the tornado and from fallen trees. A well defined convergent pattern was evident in the debris and eyewitnesses indicate the tornado had a multiple vortex structure. The damage path was around a third of a mile wide and was rated a high end F1 in this location. Further to the northeast, the tornado crossed Route MM around eight tenths of a mile north of Monterey. At this location an uninhabited home was completely destroyed with the walls pulled from numerous anchor bolts attached to the concrete foundation. Also, a wooden power pole was snapped at the base and numerous trees were snapped. The damage path was around a quarter of a mile wide and was rated a low end F2 in this location.
