Pennsylvania Gov. Tom Wolf announced on Friday the first batch of counties moving to “green,” the least restrictive phase of his reopening plan, including: Bradford, Cameron, Clarion, Clearfield, Crawford, Elk, Forest, Jefferson, Lawrence, McKean, Montour, Potter, Snyder, Sullivan, Tioga, Venango, and Warren. All of them are lightly populated counties across a northern swath of the state.

Health officials say they are working on specific guidelines for counties in the green phase.
