How Storm Sirens Work

We’ve been seeing some questions about how the storm sirens work in our County. When the National Weather Service notifies St. Croix County Emergency Communications of severe thunderstorm or tornado warnings, the sirens are activated in the affected quadrants throughout the County.

  • Quadrant 1: Hudson, North Hudson, Roberts, and Hammond
  • Quadrant 2: Somerset, Star Prairie, New Richmond, and Deer Park
  • Quadrant 3: Deer Park and Glenwood City
  • Quadrant 4: Woodville, Baldwin, and Hammond

The July 24, 2023 Storm

The strong winds from the storm that hit the Hudson area on July 24 were identified as a downburst. Downbursts are powerful winds that descend from a thunderstorm and spread out quickly once they hit the ground. Emergency Communications did not receive an initial notification from the National Weather Service for this storm. Subsequent alerts were activated when notification was received from the National Weather Service.

The safety and well-being of our residents remain our top priority. We are committed to continuously monitoring our alert systems and working with the National Weather Service to ensure swift and efficient responses to weather-related incidents.

Recovery and Assistance

  • If your property sustained damage during the storm, contact your insurance company.
  • If you experienced food loss, we recommend reaching out to your local food shelf for support.
  • For questions about other resources, we encourage you to call the United Way at 211.

Important Reminders

It’s important to remember that outdoor warning sirens are designed to alert people who are outdoors to seek shelter and more information about the warning. They’re not intended to be the alert system for people who are indoors. It is recommended to have at least 3 ways to receive information about warnings in addition to weather sirens. Other ways to receive warnings include:

  • NOAA Weather Radio
  • Internets & Apps
  • Wireless Emergency Alerts (WEA)
  • Local TV & Radio
