HUNTSVILLE, Ala. (WHNT) – The National Weather service has determined that two EF-1 tornadoes are responsible for the damage in the Lily Flagg and Dug Hill communities.

The EF-1 tornado that hit Lily Flagg had a path that was 300 yards wide and 1.96 miles long.  It started at 4:25 p.m. and lasted until 4:28 p.m.  Its peak wind velocity is estimated to be 90 mph.

About the Lily Flagg tornado, the NWS reported, “Survey summary: a tornado touched down on the west side of Memorial Parkway in the 9000 block of Craigmont Drive. In this area…several large trees were snapped or uprooted with at least one falling on the back of a house. The tornado moved northeast crossing the parkway with trees snapped along Oldfield Road. Extensive power line and power pole damage was noted at the intersection of Whitesburg Drive and Lilly Flagg Road. Several wooden poles were snapped near the base and a street light was snapped at the base as well. Several business signs were blown out in the area. The tornado was likely at its strongest point in this area reaching EF-1 intensity.

The tornado then moved across several residential neighborhoods snapping and uprooting both soft and hardwood trees. Minor damage to roofs…mainly from falling trees…was also noted. A large tree fell on a house on Valley View Drive causing major damage to the home. The occupants relayed that they heard the sirens and took cover several minutes before the tree fell through the dining room.

The tornado crossed Hickory Hill Road snapping trees and eventually causing minor tree damage in the Valley Hill Country Club area. The tornado finally lifted near Haven Street just west of Bailey Cove Road.”

Large cedar trees were snapped and twisted in this area. Other smaller softwood trees were also snapped in this area. Further east-northeast along Dug Hill Road…a large swath of cedar trees and other hardwood trees were snapped or uprooted… several snapped near the base which was consistent with EF-1 damage. A roof was also ripped off a barn on the east side of Dug Hill. The tornado then lifted just north of Raintree Road.”
