Outdoor Weather Emergency Warning Sirens
In order to better protect the residents within the Sugar Hill Community, the City of Sugar Hill has contracted with Sirens for Cities to install outdoor emergency weather warning sirens.
The City of Sugar Hill’s outdoor warning siren system consists of seven (7) sirens placed strategically throughout the city as a warning device to alert citizens outdoors of imminent severe weather. The City of Sugar Hill's Outdoor Severe Weather Warning Sirens are activated automatically when the National Weather Service issues a Tornado Warning in the Sugar Hill area. (Tornado Watch does not activate the sirens)
When residents hear the sirens, they are urged to seek shelter and turn on a radio or TV for emergency information. When the sirens are sounding for severe weather, the radio or TV announcements will provide you with information regarding the type of storm and appropriate safety actions.
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. Sirens are also subject to equipment malfunction as well as failure due to damage from lightning strikes. 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. (VHF-Atlanta KEC80, 162.55 and/or VHF-Cleveland WXJ53, 162.525) NOAA weather radios can be purchased at most electronics stores. For additional information on weather radios go to: www.nws.noaa.gov/nwr/
Warning sirens do not sound for the duration of the threat, sirens will sound for 3 minutes. Sirens can be reactivated if a new threat enters the area following the initial warning. The outdoor warning sirens are never used to announce an "all clear." This announcement is made only over radio or TV.
