GRAY — The National Weather Service issued a rare tornado warning as a line of thunderstorms raced through New Hampshire into western Maine.

NWS Meteorologist Chris Kimble says the thunderstorms packed gusts of 60 mph to 70 mph, causing downed trees and power lines in Maine and New Hampshire. Earlier, the same line of storms caused similar problems in Vermont.

Kimble said a tornado warning was issued as a radar indicated a possible tornado moving from Kingfield, Maine, to Bingham, Maine. The tornado was not immediately confirmed.

The worst damage was in central New Hampshire from Lebanon to Plymouth to an area north of Conway.
