AWS Personal Health Dashboard is able to show information such as open issues, scheduled changes and event log that may be relevant to your AWS resources.
The most convenient way to set up notifications is based on AWS Cloudwatch Events.
To notify the team when there is an open issue happening in AWS Personal Health Dashboard is create a CloudWatch Event which monitors AWS Health Event and trigger a SNS notification when there is a new event.
