Emergency alerts
Sign up for city emergency alerts to receive notifications about severe weather, road closures, water advisories, and other emergency situations. Alerts are delivered by email and text message.
Severe weather safety
During tornado warnings, move to an interior room on the lowest floor of a sturdy building. Avoid windows. During winter storms, limit travel and keep emergency supplies in your vehicle.
Emergency supply kit
Every household should maintain a basic emergency supply kit with water (one gallon per person per day for three days), non-perishable food, flashlight, batteries, first aid kit, medications, and important documents.
Rock County Emergency Management
