The count of confirmed tornadoes that struck Maryland on June 1 reached a dozen on Thursday as meteorologists continued to survey radar images and storm damage.

Tornadoes added to the list most recently included those confirmed in Queen Anne's County, North Laurel in Howard County, near Poolesville in Montgomery County, and in Allegany County. Those previously confirmed struck the Fallston area, near BWI Marshall Airport, south of Westminster, and near Mount Airy and Damascus.

Meteorologists are still in the process of reviewing radar images that showed strong rotation and exploring the areas for damage. One area of focus is near Freeland and Maryland Line in northern Baltimore County, said Steve Zubrick, science and operations officer at the National Weather Service's Sterling, Va., office.

The Queen Anne's County tornado was confirmed Wednesday by the Mount Holly, N.J., weather service office.

Fourteen tornadoes confirmed in Maryland on July 27, 1994, is the record for most seen in one day, with the July 1 ranking second, surpassing the nine tornadoes confirmed Aug. 28, 1992. Zubrick said he did not put too much stock in those rankings, though, which date back to about 1950.

"We find tornado damage that might consist of a dozen trees damaged," Zubrick said of current storm evaluation. "In the old days they wouldn’t even give that the time of day."

Also, Zubrick emphasized that the total could continue to change.

"We always reserve the right to go back and say, 'Oh, maybe this wasn’t a tornado.' But it was a busy day."
