1.4 SE Fransisco - 1.8 ESE Fransisco A tornado produced EF-1 damage near Highway 25 between mile markers 25 and 26. The primary damage indicators were trees on both sides of highway. The beginning of the tornado damage was observed on the west side of Hwy 25 on the downslope of an east-facing ridge. An extensive area of downed trees was noted along the slope as it approached the valley. As the tornado tracked east-northeast back up a west-facing slope along Hwy 25, trees were uprooted across the road and a distinctive cyclonic circulation approximately 200 yd wide was observed. Due to inaccessible locations, the damage assessment team approximated the touchdown near the mid-slope of the ridge west of Hwy 25 and the lifting point on lower half of the slope on the east side of Hwy 25. Start: 34.9682/-86.2307 End: 34.9692/-86.2217
