Location: SUNNYBROOK

Reported by: NWS Storm Survey

A tornado touched down just north of the intersection of Merrymans Mill Road and MD-146 Jarrettsville Pike, where minor tree damage and snapped tree tops were observed.
The tornado continued moving northeastward producing more significant tree damage as it moved east of MD-146 Jarrettsville Pike towards the southern end of Overshot Court. The most extensive tree damage was noted along Overshot Court where multiple hardwood and softwood trees were uprooted and snapped. About 100 trees were damaged on Overshot Court, with many uprooted trees falling in a convergent, crossing manner and pointed to the west-to-north (generally along and left of the tornado track). At least 20 hardwood trees ranging between 10 and 20 inches in diameter were snapped off about 10 feet above the ground. Some of the uprooted trees also fell towards the east. A house on Overshot Court had siding damage, lost a portion of its eave on the northeast side of the house, had a shutter blown off, and a flagpole blown down. Siding from this house was found 120 yards to the northwest of the house.
Eyewitness accounts were taken from several residents along Overshot Court. They all relayed a similar story of relatively quiet conditions followed by a loud and incessant roaring sound, with reduced visibility due to heavy rain and swirling winds. One resident texted that they entered their basement when they heard the loud roar, with the timestamp of that text being 4:57 PM EDT. All residents noted the damage occurred quickly lasting well less than one minute.
As the tornado moved northeastward, it crossed wooded areas south of the Carroll Manor Recreation Council Building on MD-145 Sweet Air Road, where limited tree damage was noted. No damage was noted along Fox Run Court, but as the tornado crossed the 14000 block of Blenheim Road, several trees were damaged; several were uprooted and several were topped. One large 2-foot-in-diameter tree was uprooted facing toward the west, while a trampoline from a residence was blown over 200 yards toward the east, and several softwood pine trees were snapped. The large uprooted tree damaged a section of a covered porch.
The tornado produced only minor tree damage as it moved northeastward from Blenheim Road, and may have lifted briefly as it crossed MD-145 Sweet Air Road just west of Manor Road. As the tornado crossed Manor Road just north of MD-145 Sweet Air Road, minor tree damage was noted mainly with mainly a few large tree branches down.
Farther to the northeast, the tornado produced tree damage to a residence at the end of Cremson Drive off of Manor Road. A large hardwood tree about 20 inches in diameter was twisted off 10 feet up from the ground. A resident at this location described hearing a loud sound akin to a freight train and observed the tornado cause the aforementioned damage. The resident noted he was in his basement because of a Tornado Warning, with the damage occurring 5 minutes after his phone had alerted him to the Tornado Warning.
No further damage was noted to the northeast of the location on Cremson Drive, and the tornado likely lifted before crossing Maple Ridge Court.
