The National Weather Service in Wilmington OH has confirmed a tornado near Celina in Mercer County Ohio on Sunday afternoon, November 5, 2017.

Law enforcement observed a funnel cloud near the intersection of Main Street and Schunk Road. Just to the northeast of this report is where it appears the tornado first touched down, where multiple tree limbs were knocked down between Main Street and West Bank Road.

It is believed that the tornado then skirted Grand Lake St. Marys, producing minor tree and structural damage near the corner of  Lake Shore Drive and Elmgrove Avenue. The tornado then likely moved back over a small portion of Grand Lake St. Marys before knocking down a fence and a few small trees at the back parking
lot of Wendy’s on E Market Street. A one story home on Vine Street also had shingles removed from about 10 percent of its roof.

Further east on E Market Street, the tornado intensified as it impacted Lakeshore Auto Sales. This business had its roof completely destroyed. Along Lake Street, several large branches were knocked down on one property, with significant debris
splatter on the east-facing side of a home along with some removal of siding.

Further east on E Market Street, another business had a significant portion of its roof removed, and windows at the front of the business were broken.

Onto the 1100 block of E Livingston Street, tree damage was common and several of the homes also exhibited minor roof damage. One of the homes also had one large hardwood tree knocked down onto its second floor, producing significant roof damage.

To the northeast, an outbuilding associated with a business on Grand Lake Road was completely destroyed. On the other side of Grand Lake Road, significant debris wrapped around a fence on Montgomery Field. Trees were also uprooted on adjacent May Street.

The most significant damage was then observed beginning at Crown Equipment Corporation. A significant portion of the roof was removed, and exterior walls on the southwest side of the building also collapsed. Damage was also noted on the east-facing side of the building.

Businesses along Havermann Road were also affected, most notably C-Town Wings where the front windows were blown out and the Dollar General which sustained considerable structural damage including roof collapse and exterior wall failure. Observed damage from the Crown Equipment Corporation to the Dollar General was consistent with EF2 tornadic winds.

Several businesses within a strip mall along Havermann Road also sustained some damage, particularly a sports store where the front doors were blown in and a portion of the roof collapsed into the store.

Damage to the northeast of the strip mall became more sparse,  however some trees were downed near the intersection of Howick Road and Riley Road. The end of the tornado appears to have occurred near the 8000 block of Riley Road.

The National Weather Service would like to thank local officials in Mercer County and Celina, including Mercer County Emergency Management; Van Wert County Emergency Management, the Ohio Emergency Management Agency and interviewed eyewitnesses for their assistance with this storm damage survey.

A survey team from the National Weather Service in Wilmington Ohio, with assistance from the Mercer County Emergency Management Agency and Ohio Emergency Management Agency, confirmed a tornado that occurred in western Mercer County on Sunday afternoon, November 5th 2017.

The tornado path surveyed in western Mercer County is the tail-end of a long track tornado that moved out of Jay County, Indiana.

(Please see Below) additional statements from the NWS offices in Indiana for details on earlier segments of this tornado.

The tornado crossed into Ohio (Mercer County) near the  intersection of St. Anthony Road and County Road 235. The tornado traveled northeast for just more than 8 miles before terminating in a wooded area north of Carmel Church Road and west of Now Road. A few pieces of light debris were carried slightly further to the northeast, but the tornado is not believed to have been on the ground east of Now Road.

The vast majority of the surveyed path in Mercer County contained damage consistent with winds of 60-100 MPH, including scattered tree damage, significant damage or destruction of outbuildings,  and minor damage to well-built homes. In all, 20-25 different  properties were affected by this tornado in Mercer County.

Damage was determined to be most significant at two different locations along the track, with wind speeds estimated at 120 MPH, or EF2 on the Enhanced Fujita Scale. The first of these locations was a dairy farm on State Route 49 north of St. Anthony Road. At this location, a small home had its roof completely removed, with the removal and collapse of some exterior walls. It was noted that while some walls were collapsed, toe nailing was the primaryanchoring mechanism for the roof and walls on this home. Barns and outbuildings on the property were significantly damaged or  destroyed, and debris from this location was deposited up to a mile downstream.

The second location exhibiting EF2-rated damage was at a property on Mud Pike Road just east of Township Line Road. Here, a well-built residence had the majority of its roof removed, including the entirety of the garage roof. Sections of brick facade were removed from the exterior walls of the home, with significant mud splatter on the east-facing exterior wall. A large well- constructed barn adjacent to this home was completely demolished, with debris thrown about a mile downstream of its source location.

Throughout its track through Mercer County, this tornado exhibited a large and relatively uniform width, with damage observed that indicate a width of near or slightly greater than three tenths of a mile. Some minor damage was even observed outside of this estimated width. Downstream of some of the affected properties, debris fields were observed to be long, wide, and relatively uniform.
