Outdoor Sirens

Allen operates fourteen outdoor warning sirens that sound during severe weather events, including large hailstorms, heavy winds and tornado warnings. Though the sirens are placed strategically throughout the city, they are designed to warn people who are outdoors. People who are inside may not hear them, as air conditioning, thunder, wind, rain and other conditions can drown out the sound.

The City of Allen highly recommends each home and business have other means to receive warnings and notifications, including internet, radio, television or a NOAA weather radio.
