severe hazard. Isolated instances of large hail could occur as well.

The severe thunderstorm watch area is approximately along and 70
statute miles east and west of a line from 25 miles northeast of
Martinsburg WV to 40 miles southeast of Lynchburg VA. For a complete
depiction of the watch see the associated watch outline update
