The Kent Office of Emergency Management is cautioning that dangerous heat returns this week.  Very warm and fairly humid conditions are expected today, with maximum heat indices topping out in the low to mid-90s in the valleys.  Residents are reminded to stay hydrated if spending time outdoor.  The Kent Office of Emergency Management and the Kent Memorial Library have partnered to provide a cooling center for those individuals needing relief from the heat. The cooling center is open during business hours at the library, during the week 10am to 5:30pm, Saturday 10 to 4, and Sunday noon to 4.
