Arctic air that arrived in New Jersey over the weekend spurred at least 15 out of NJ's 21 counties to issue Code Blue alerts as of Monday, Jan. 21.

Through the state Code Blue law, signed in May 2017, counties issue alerts whenever the temperature drops below 25 degrees Fahrenheit without precipitation, or below 32 degrees Fahrenheit with precipitation. Code Blue procedures also apply when the National Weather Service wind chill temperature is at 0 degrees Fahrenheit or less for a period of two hours or more.

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 designated 'warming centers' around the state are at local library branches and senior centers. The coldest day of 2019 so far happened to fall on a federal holiday, Martin Luther King Jr. Day, and many county facilities were closed.

Mercer County officials said the Lawrence, Ewing, Hickory Corner and West Windsor branches of the County Library System are open from 9:30 a.m. to 5 p.m.

Despite the strides made with Code Blue efforts, Somerset County does not have overnight shelters available. Resident there are advised to call the County Office of Emergency Management for help with overnight placement at 908-725-5070.

Other active code blue alerts: Atlantic, Bergen, Burlington,Camden, Cumberland, Essex, Hudson, Hunterdon, Monmouth, Morris, Ocean, Passaic, Salem, Union
