As New Jersey deals with a blast of chilly temperatures, Code Blue alerts have been issued in 15 of the state's 21 counties through at least Wednesday night into Thursday morning.

  • County notifications:
  • Bergen County
  • Burlington County
  • Camden County
  • Cape May County
  • Essex County
  • Hudson County
  • Hunterdon County
  • Middlesex County
  • Monmouth County
  • Ocean County
  • Union County

In Morris County, the alert is for each overnight through Saturday, Nov. 16.

In Sussex County, the Code Blue alert is now through Sunday morning, Nov. 17.

Passaic County and Somerset County both have Code Blue alerts "until further notice."

A Code Blue alert "enables authorities to take homeless adults to shelter programs that have agreed to make additional beds available," according to the state's NJ211 site. Warming centers are also opened and advertised through local media and social media.

Many of the state's designated warming centers are at local library branches and senior centers. For a full list, organized by county, click here.

The state’s Code Blue law, signed in May 2017, calls for such alerts whenever the temperature drops below 25 degrees without precipitation, or below 32 degrees with precipitation.

Code Blue procedures also apply when the National Weather Service wind chill temperature is at 0 degrees or less for a period of two hours or more.
