KGRAHAMThe national radar mosaic for the moment the first event began.
2 thunderstorm wind, 1 tornado. Local standard time, as filed.
Roof and structural damage was reported to a residence north of Picayune.
Isolated wind damage was noted in an area from approximately 5 miles west of Mcneil to just northwest of Mcneil. Damage consisted primarily of a few downed large tree limbs. Minor roof damage was also reported to a mobile home by emergency management. Event time was estimated based on radar.
A tornado touched down just west of Mississippi Highway 53 and south of Mcneil-Mchenry Road in Pearl River County. Near where the tornado touched down, an outbuilding was destroyed and tree limbs were downed. As the tornado tracked east-northeast, more tree limbs were downed and a few wooden power poles and trees were snapped. Shortly after travelling east of Highway 53, a mobile home and outbuilding were damaged. Additional tree damage continued farther east-northeast before the tornado lifted.
