RALEIGH, N.C. — The Latest on a winter storm that hit North Carolina (all times local):

3:50 p.m.

North Carolina’s governor is warning residents to remain cautious of icy roads as frigid temperatures hang around into the weekend.

Gov. Roy Cooper issued a statement Friday that many primary roads and highways have been cleared, but treacherous patches remain — especially on secondary roads. Troopers have responded to nearly 1,300 collisions since the snow storm blew in Wednesday, with the majority in the first 24 hours of the storm. Four traffic deaths are attributed to the storm.

Power outages have also dropped to about 1,200, mostly in Wake County.

The National Weather Service extended a winter weather advisory for the central part of the state into Saturday, due to cold temperatures, wind chill and residual snow and ice. Forecasters also issued a weather statement warning of similar conditions along the coast.

Authorities have confirmed a fourth North Carolina death because of the winter storm that blanketed the state.

Surf City Police Chief Ron Shanahan released a statement that officers found a vehicle submerged in a canal during the snow storm early Thursday and were investigating the cause. Shanahan said 20-year-old Dax Christopher Baker was found dead inside.

State Emergency Management spokesman Keith Acree said Friday that investigators have determined the winter storm caused the driver to slide off the road and into the canal.

More progress has been made on restoring power to those who lost it in the storm. Acree said Friday there were only about 2,300 outages across the state, with only a small fraction of those in hard-hit coastal areas. That’s down from a peak of about 20,000 outages after the storm blew in Wednesday.

8:25 a.m.

It’s bitterly cold in North Carolina after a storm dumped more than 6 inches (15 centimeters) of snow in the eastern part of the state.

The National Weather service issued a winter weather advisory Friday for about two dozen counties in central and eastern North Carolina. Forecasters say says snow cover and the ice create dangerous driving conditions.

A wind chill advisory is in effect for almost the entire the state. Wind chill readings are ranging from minus 25 degrees (-32 Celsius) in the mountains to around 0 degrees (-18 Celsius) on the Outer Banks.

Schools and some government offices are still closed in parts of central and eastern North Carolina.

As the storm moved north along the East Coast, parts of the Outer Banks were hit with hurricane force winds.
