The City of Saskatoon says with warmer temperatures expected over the long weekend, the Extreme Heat Emergency Response will be activated tomorrow (Fri) and continue through Monday. When the hot weather becomes dangerous, the Saskatoon Emergency Management Organization coordinates a response plan to help protect those who are most vulnerable. It provides residents with cooling locations, outreach services, wellness checks and water distribution. As part of the Emergency Response Plan, all spray pad hours will be extended to 10 pm from Friday through Monday.
