What happened
Small streams across the northern portion of the county flooded. ||An elderly couple was driving home along Linscott Run. This is a small tributary to Federal Creek near Amesville.

The wife was using a walker due to recent hip surgery. She slipped and the husband could not hold on to her. The current swept her away. The fire department located her body around dawn on the 5th, about a half mile downstream. The husband was helped to safety by neighbors using a garden hose. Route 550 was also flooded in Amesville. ||Several streets in Nelsonville were flooded including along Dorr Run and Pleasant View Road.

What happened
A combination of snow, sleet and freezing rain created slippery travel conditions across portions of southeast Ohio on the morning of the 8th as an upper level disturbance pulled a stream of Gulf moisture north. This moisture moved over a very cold air mass, resulting in the wintry mix of precipitation. Multiple traffic accidents occurred due to icy roads. One resulted in a fatality, in Athens County a semi truck driver lost control and slid over a bridge falling onto the road below. The driver, a 56 year old man from Georgia, died in the accident.
