Douglas County's outdoor warning siren system consists of 44 sirens placed strategically throughout the county as an early warning device to alert citizens outdoors of imminent severe weather. A map of siren coverage is linked at the bottom of this page.
The outdoor warning siren system is an effective method of outdoor notification, but Douglas County Emergency Management recommends a duplication of ways to receive warnings and notifications. In other words, it is best to have more than one way to be warned of potential dangers. Warning and notification can be received by monitoring the following:
Developed as an early warning system of severe weather to persons outdoors, the system should not be relied upon for early warning to individuals indoors. Air-conditioning, thunder, wind, rain, and other conditions can cause the sirens not to be heard indoors (even if sirens can be heard indoors during tests). Sirens are also subject to equipment malfunction as well as failure due to damage from lightning strikes. This is another reason to have numerous ways to receive warning and notification. Furthermore, sirens do not provide any information concerning the type of threat or exact location of the potential danger. For this reason, if you are outdoors and hear a siren, you should seek shelter immediately as the threat may be in your immediate area.
Individuals, families, and businesses are strongly encouraged to use NOAA weather radios to receive warnings and emergency information. Douglas County Emergency Management sells these radios at cost for $30.00.
