"As Philadelphia welcomes the world and celebrates our nation's 250th anniversary, I want every resident and visitor alike to know that there are places across our city to cool off and find relief from the heat," saidMayor Cherelle L. Parker.

A declaration of a Heat Health Emergency activates the City's emergency heat programs, which include the Philadelphia Corporation for Aging's (PCA) Heatline, cooling centers, home visits by special field teams, enhanced daytime outreach for people experiencing homelessness.

It also serves as a reminder for the public to safely check on older friends, relatives, and neighbors from a distance.
