...Summary...
The National Weather Service in Wilmington OH has confirmed a
tornado northeast of Hamersville in Brown County Ohio on February
25 2018.

Damage assessed to be tornadic is first believed to have occurred
near Lucas Road about one mile northeast of Hamersville. More
significant damage was observed near the intersection of White Oak
Valley Road and Smokey Row Road, where a well-built home suffered
partial roof loss and additional loss of roofing material. At
another property on White Oak Valley Road, a trailer was flipped
over. Tree damage was extensive along Smokey Row Road, especially
near its intersection with Vinegar Hill Road.

On New Hope - McKinley Road, about a half mile east of US-68, a
mobile home had its roof completely removed. Debris from this roof
was observed thrown about 500 yards downstream (northeast) of its
origin. Additional tree damage was observed along New Hope - White
Oak Station Road.

In addition to the tornadic damage described above, the National
Weather Service storm survey observed non-tornadic damage across a
much wider area. This area of damage extended about 13 miles in 
length, stretching from far southeastern Clermont County through
north central Brown County. This straight-line wind damage
affected areas near Feesburg and Hamersville, and was observed on
both sides of the surveyed tornadic circulation. This damage
consisted of additional tree and outbuilding damage, including the
destruction of a few outbuildings.

The National Weather Service in Wilmington Ohio would like to 
thank officials with the Brown County and Ohio Emergency 
Management Agencies for their help with this survey.
