A new protocol has been put in place for Pittsburgh Public Schools in lieu of this weekend’s heat wave and any future summer temperatures that could affect students.

PPS announced Tuesday that it will monitor the temperatures inside of its school buildings when outside temperatures are expected to be 85 degrees or higher, OR if the heat index readings from the National Weather Service exceed 90 degrees. The school said in a press release that any excessive heat could lead to a switch to remote learning.

There are currently over 40 buildings in the Pittsburgh Public Schools system that do not have sufficient air conditioning systems.
