An alert system provided to Platte County by Konexus AlertSense 

Sign up to receive emergency alerts and severe weather warnings that could directly impact you and your family

Platte County is able to send you emergency alerts via text message, email, pager, or voice mail (in extreme cases), based on your preferences. It is important that we collect this contact information because many households no longer utilize traditional land-based telephone lines.
The system is intended to be used for emergency alerts, as well as non-emergency incidents that may have significant impacts to residents. Emergency Alerts could be related to specific hazards that require some kind of action be taken such as evacuation, shelter in place, boil water orders, etc. Non-emergency alerts could include significant transportation problems with prolonged impacts or significant ongoing police or fire activity. This list is not meant to be all inclusive, and demonstrates that this system will not be used for routine information. In addition to receiving information on your wireless device, you may also receive notification on your land telephone line (if you have one) depending on the type of incident or event.
Please provide your address and preferred method(s) of contact. Adding your address will allow tailoring so you do not receive alerts that don’t pertain to your geographical area.
These alerts are provided free of charge, however standard text messaging rates and other charges may apply.
