If I don't reside in a participating city, can I still get NotifyJoCo alerts?

Yes. All Johnson County Kansas residents will receive county-wide emergency alerts. All WaterOne customers will receive emergency alerts. However, if you live in a city that is not yet participating in NotifyJoCo, you will not receive local city-wide alerts or non-emergency alerts from NotifyJoCo.
