Siren Test is Wednesday Morning in Rochester

  Federal Siren 

Summer Siren Test Schedule Begins April 5, 2017

Siren Test Day is Wednesday morning in Rochester. Sirens are a way to alert you to go indoors and seek shelter. A siren system is used to alert people outdoors. Sirens are used to warn of tornados, or other life-threatening conditions. When you hear a siren, go indoors and tune to local news for more information. Another source for updated information is Rochester Alert website.

Fall/Winter test schedule: Partial 1 minute test first Wednesday morning (October - March). Growl test on remaining Wednesday mornings at 10 am.

What is a growl test? Is the siren broken?

A "growl" test is performed 2nd, 4th, 5th Wednesdays throughout the summer months (April - September). A growl test momentarily starts the siren, and quickly shuts down. It might seem like the siren is broken, but it's just a growl test.

Siren system test is every Wednesday morning at 10 am. Testing the system allows us to make sure sirens will work when needed.

Summer test schedule: Full 3 minute test first & third Wednesday mornings (April - September) at 10 am.

From April through September, a full 3 minute siren test will be heard the first & third Wednesday mornings, weather permitting. This is a routine test to ensure the sirens operate when needed. On the 2nd, 4th, and 5th Wednesdays, a quick "growl" test happens. Questions? Contact City of Rochester Emergency Management Director.
