  A civil danger warning (SAME code: CDW) is a warning issued through the Emergency Alert System (EAS) in the United States to warn the public of an event that presents danger to a significant civilian population. It is typically issued by a local or state authority and is relayed by the National Weather Service. The warning usually mentions a specific hazard such as contaminated water supply, active shooting, unexpected weather alert such as causing roads to be extremely dangerous, major accident, or an imminent or in-progress military or terrorist attack. It may also provide instructions for protective action such as to evacuate, shelter-in-place, boil water or seek medical treatment. The warning has a higher priority than a local area emergency (LAE).
  
  ## Examples
