Monthly Siren Testing Reminder: Platteville & Gilcrest
Hello, Platteville and Gilcrest residents! This is a reminder that on the first Saturday of every month (April through October), both towns conduct a test of the audible alert siren system at approximately 10:00 AM.
🗓️ Test Details
Duration: A brief test lasting about one minute.
Schedule: Monthly on the first Saturday (April–October).
Weather Policy: To avoid confusion, tests will be canceled if there is an active weather event or significant cloud cover.
🏠 Indoor vs. Outdoor Safety
Please remember that sirens are designed to alert those who are outside to seek shelter; they are not always audible indoors. For indoor notifications, we strongly encourage all residents to sign up for CodeRed.
🚨 What to do in a Real Emergency
If the sirens sound outside of a scheduled test:
Seek Shelter: Move to the innermost room or hallway of your residence immediately.
Stay Safe: Stay away from windows and do not go outside.
Emergency Warning: A 3-minute steady tone (may be sounded multiple times).
"All Clear": A 30-second up-and-down tone.
Stay Informed: Follow instructions provided via CodeRed, radio, or local news.
