An EF0 tornado touched down in Montgomery County on Monday afternoon, according to the National Weather Service, and meteorologists were also investigating a possible tornado in southern Pennsylvania.
In the Silver Spring area, a tornado with peak winds of about 70 miles per hour toppled several large trees and sent them crashing into houses, NWS officials said. No injuries were reported.
The tornado struck around 3:48 p.m. in an area north of where University Boulevard and Colesville Road converge in Silver Spring. It started near Dennis Avenue and Royalton Road and traveled one-fifth of a mile to Lockridge Drive.
The tornado came as a line of storms passed through the Washington suburbs and Baltimore on Monday afternoon.
Separately, weather service meteorologists in Pennsylvania said they were investigating possible tornado damage in York County, just over the state line. A tornado warning was issued there about 1:45 p.m. Monday when radar indicated strong rotation in storm clouds.
