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.

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.
