Athena is at the door.

Winter Storm Athena has forced a winter weather advisory for much of North Jersey, with the National Weather Service forecasting snow, sleet and rain for Wednesday and a snowy mix for Thursday. Temperatures are expected to be at or just below freezing Wednesday and in the low 40s on Thursday.

The winter weather advisory is in effect until 6 a.m. Thursday, and 60mph wind gusts could blow over much of the area.

The Weather Channel is predicting that the “subtle” system will strengthen as it moves up the coast.

Accuweather.com is reporting that snowflakes are falling in Pennsauken, which is located across from Philadelphia on the Delaware River.

According to meteorologists, snow is expected to begin falling in Central Jersey at noon and change over to rain and warmer air moves further inland. Some coastal flooding could occur as well.

North Jersey could get hit with snow, rain, and high winds, which could hamper the region’s recovery from Hurricane Sandy. That storm left millions without power and heat for days. Some North Jersey residents still don’t have power and are pleading with PSE&G and JCP&L to get their power back.

"You can probably expect that if you've gotten power, some of you may lose power again," Christie said.
