Information on Wireless Emergency Alerts

Why did I receive a WEA (Wireless Emergencey Alert), or cell phone alert when there was no warning in effect for my location?


A tornado warning was in effect earlier this afternoon for Stephenson County, IL. For those in the southern portions of Green, Rock, or Lafayette counties, your cell phone may have alerted for this tornado warning.  WEA messages are broadcast using radio-like technology from cell towers in, and sometimes around, the actual warning area. Therefore, an alert can reach cell phones outside of the actual warning area depending on the broadcast range of the cell towers which broadcast the alert. This overreach is typically more prevalent in rural areas than in more densely populated cities. Whenever you receive a WEA, you should seek additional information on radio, TV, or other sources for detailed information on the warning.
