Tornado in HOWARD, MARYLAND

Location: GUILFORD
Tornado F-scale: EF0
Property damage: 50.00K
Reported by: NWS Storm Survey

A brief EF0 tornado touched down at the Snowden Square shopping mall. Damage was limited to a quarter-mile path, and peak wind gusts were estimated to have been around 70 mph.
Initial tree damage was noted in front of the Goodwill store where two ornamental trees were snapped at their base. Small branch and leaf litter was noted as the tornado passed over the open parking lot towards a BJs store. As the tornado passed over a BJ`s store and tire center, a section of the wall facade, estimated about 50 feet by 20 feet, was removed. The affected wall was on the opposite side from the direction of storm motion. An employee at the tire center noted that nearby shopping carts were lofted and then rapidly blown to the north. The store manager noted the time of the incident from a video taken in the store shortly after it happened. That time matched the time that a tight tornadic circulation with hook echo was noted right over the shopping center by the nearby TBWI terminal doppler weather radar. TBWI
radar had a good view of the event, and was just 10 miles away and sampling only 600 feet off the ground over the shopping center.
Final damage was noted to two more mid-sized trees at the end of Snowden Square Drive. Large branches were snapped off and thrown in multiple directions, north to southeast. Trash and debris was also noted to have been blown to the southeast into an adjacent field. No further damage was noted past this point.
