Stay apprised in real time by email of hazardous weather conditions in Delaware when a news release posts on news.delaware.gov concerning events like snow, ice, blizzards or hurricanes by subscribing to weather alerts.
Delaware Emergency Notification System
The Delaware Emergency Notification System (DENS) is the primary system used to warm Delaware citizens about emergency situations.
DENS allows 911 centers to send messages to specific locations or larger areas that might be affected by the emergency event. Since many homes and businesses do not use landline phones today, you can register your mobile phone in the DENS system.
Plan ahead for any emergency by giving 9-1-1 the information they need to help you fast by registering at Smart911.
Environmental Release Notifications
DERNS alerts the public of the release or discharge of contaminants or pollutants locally or statewide when thresholds are exceeded.
In response to the 2001 Delaware law codified in Title 7, Delaware Code, Section 6028(a), the Department of Natural Resources and Environmental Control (DNREC) developed the notification system to promptly alert Delawareans to releases or discharges of contaminants or pollutants that meet or exceed certain thresholds in their neighborhoods or throughout the state.

Driving Warnings and Restrictions Due to Unsafe Conditions
When there are severe weather events or other unsafe conditions, the Governor may issue a Driving Warning, Restriction, or Ban. Press releases announcing these conditions are posted on Delaware News' weather notifications area. You can also sign up to receive weather-related press releases.
Level 1 Driving Warning
Drivers are discouraged from operating a motor vehicle on the state’s roadways, unless there is a significant safety, health, or business reason to do so. During a level 1 Driving Warning, all citizens are asked to drive with extreme caution.
Level 2 Driving Restriction
Travel on the roads is restricted to emergency workers, public utilities, healthcare providers including hospital staff, public and private operators of snow removal equipment, private sector food and fuel deliveries. Industries, companies or organizations that have been provided a waiver, are also permitted to be on the road, including businesses with pressing continuity and operational issues.
Level 3 Driving Ban
Complete ban on driving except for first responders, utility personnel, and public or private snow removal. Businesses and organizations should adjust work schedules so that employees do not need to be on the roads during a Level 3 Driving Ban.
Level 3 Bans are different from Level 2 Restrictions. Level 2 allows people with waivers and essential personnel to remain on the road, whereas a Level 3 Bans are much stricter, only allowing emergency personnel.
Waivers are not valid during a State of Emergency Level 3 driving ban.
