NEWARK - People across New Jersey are dealing with bitter cold temperatures.

In many parts of the Garden State, the temperature barely reached 30 degrees. Temperatures were mostly in the teens Tuesday morning.

Health officials say that wearing layers is important when temperatures get this cold. People should try to limit the amount of skin that is exposed to the elements by making sure they wear hats and gloves.

Several towns have issued “Cold Blue” alerts and have opened shelters for the homeless or anyone who may not have heat in their homes.

Tuesday’s overnight temperatures could dip into the teens and even single digits.

News 12 New Jersey Meteorologist Dave Curren says that Wednesday should warm up as highs climb into the high-30s and low-40s.
