New Jersey weather: 19 counties under 'Code Blue' declaration as arctic blast moves through region

PENNASUKEN, New Jersey (WPVI) -- Nineteen counties in New Jersey are under a "Code Blue" declaration for Tuesday and some into Wednesday due to the cold conditions. Parts of the Garden State also saw their first snow of the season as an arctic blast moved through the region.

The little bit of snow took many people by surprise, even though it didn't last long. Folks were out all bundled up as the snow dusted the grass and parked cars.

"I didn't think it was going to be snow," said Lucy Okonkwo, of Merchantville, New Jersey. "I don't like it."

The cold is also causing some problems. In Atlantic City, city officials had to close city hall because the building does not have heat. There has been no word on ow long the repairs will take.

A "Code Blue" is declared when the temperatures drop below freezing and conditions pose a threat to unsheltered people. During the such cold weather events, the county offices of emergency management will initiate a "Code Blue," which enables officials to make shelter arrangements for adults experiencing homelessness, including warming shelters.
