HARRISBURG, Pa. - Thirteen more counties in western Pennsylvania moved from Governor Tom Wolf's red to yellow phase on Friday.

That means those counties can take the first step to start easing some restrictions on work and social interaction.

Schools, gyms, indoor recreation centers, and hair and nail salons remain closed, and limitations on large gatherings are still in place.

Wolf is expected to announce Friday the next set of counties that will soon be able to see the tightest pandemic restrictions lifted.

Counties and lawmakers continue to pressure him to ease his orders, but Wolf said he hasn't changed his criteria for deciding which counties can emerge from his stay-at-home order and his business shutdown order.

His health secretary echoed that, saying the administration will continue to count cases in prisons, factories and nursing homes in a county’s total. That is bad news for counties that blame much of their outbreak on a single institution.

Counties in the red phase, including eastern and southeastern Pennsylvania, are under a stay-at-home order through June 4.
