  4. Use air conditioning or visit cooling centers
  5. Never leave children or pets in parked vehicles

As this heatwave persists, it's crucial for residents in affected areas to stay informed about local weather updates and follow safety guidelines. Remember, heat-related illnesses can be prevented with proper precautions.
