[ARCHIVED] Severe Weather Notice About Use of Sirens

City of Allen outdoor warning siren

There is a possibility of severe storms today. The City of Allen highly recommends each home and business have means to receive weather warnings and notifications, including internet, weather apps, radio, television or a NOAA weather radio. Allen operates 14 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 only. People who are inside may not hear them, as air conditioning, thunder, wind, rain and other conditions can drown out the sound. 

If activated, the sirens will sound a wail tone for three (3) minutes to indicate any of the following conditions:

  • Hail 1 inch or greater in size
  • Severe Thunderstorm Warning from the National Weather Service with winds forecast more than 70 mph
  • Tornado Warning from the National Weather Service naming Allen in the path

Please note that outdoor warning sirens from neighboring cities may be heard in some areas of Allen; however, warnings initiated by other cities may be based on other weather conditions or criteria.
