UPDATE – 7:01 a.m.: All Chatham schools and school offices will be closed on Wednesday due to the weather, officials announced Wednesday morning.

The district had announced a delayed opening for Wednesday morning but altered the announcement to cancel school after more ice and freezing rain fell Tuesday night.

Chatham Borough offices will have a delayed opening.

The Library of the Chathams closed at 4 p.m. Tuesday due to weather, said Borough Mayor Nelson Vaughan.

While Chatham schools remained open Tuesday, all after-school activities have been postponed as a record snowfall in January has given way to a stormy start to February.

The Cougars' basketball games against Pequannock High School and the fencing team's match against Morristown High have been postponed.

The National Weather Service has issued a winter storm warning for much of Northern New Jersey from late Monday night through Wednesday evening with snow, sleet and freezing rain expected the next couple of days.

After a record 16.1 inches fell in January, snow has mixed with sleet Tuesday before changing to freezing rain Tuesday night and possibly ending as snow on Wednesday, according to the National Weather Service.

The storm is expected to produce anywhere between 4 and 10 inches of snow and some ice accumulation. The precipitation is expected to taper off Tuesday afternoon before intensifying again during the night into Wednesday, the National Weather Service said.

The icy conditions will likely impact road conditions and could cause down limbs and widespread power outages. JCP&L maintains an online outage map here. PSE&G has its outage map here.

Patch will continue to update this story throughout the storm, including any school delays, closures and event postponements.
