Testing Wednesday: Fifteen new outdoor warning sirens in and around downtown Minneapolis

Wednesday, May 2, as part of the regular monthly outdoor warning siren test, the City is sounding 15 new outdoor warning sirens installed in downtown. These new sirens meet a Federal Emergency Management Agency (FEMA) guideline that the sound of the sirens exceed the ambient noise level by at least 10 decibels. The new sirens are 105-110 decibels.

The new siren locations are:

These complement 50 existing larger sirens around the city. The total of the 65 sirens will bring the entire city up to the FEMA guideline’s level. Phase 1 of the project was completed in 2013 with 43 sirens around the city; Phase 2 was completed in 2017 with seven sirens in and around downtown.

What to do when you hear the sirens
For severe weather warnings, outdoor warning siren activation in Hennepin County is based on the following criteria:

People who are in their vehicles when the sirens sound should seek shelter immediately. The safest place to be is in a sturdy building on the lowest level away from windows. If there is not a building nearby and a tornado is approaching, people should quickly get as far away from the road and cars as possible and lie in a low area covering their heads with their arms. They should stay away from overpasses as the bridge may collapse or create a wind tunnel with debris.
