Sign Up for New County-wide Emergency Alerts

Olathe residents can now receive direct messages about impending emergencies in Olathe and surrounding Johnson County with the launch of NotifyJoCo, a free, mass communications system that sends alerts about incidents from evacuations to water outages, via phone, text or email.

The system, which is free to the public, is an unprecedented effort between Johnson County, Water One, and the cities of Lenexa, Mission Hills, Olathe, Overland Park, Prairie Village and Shawnee.

As part of Severe Weather Awareness Week, a test of the NotifyJoCo system will be conducted at 10:00 a.m. on Tuesday, March 5.  A test message will be sent to approximately 140,000 residents and businesses in Johnson County who have published phone numbers.  Anyone who lives, works, or plays in Johnson County is encouraged to go to to set up a free NotifyJoCo account and personalize their contact preferences.  Account holders can identify multiple locations they want to receive emergency messages about and they can sign up to receive emails, texts, or phone calls on multiple devices.
