New Jerseyans braced for another round of snowy weather on Monday, as a large storm system moving up the mid-Atlantic coast was expected to dump as much as 8 inches of snow on parts of the Garden State.

The storm comes one day after another system dropped a mix of snow, freezing rain and sleet that created treacherous travel conditions across the state, causing hundreds of accidents and claiming the lives of three people.

The National Weather Service issued a winter storm watch for most of central and southern Jersey, which was to remain in effect through Tuesday morning. Forecasters said the snow would likely start sometime Monday afternoon, with the heaviest amounts expected at night.

Anywhere from 4 to 8 inches of snow was possible in central and southern areas, while 2 to 4 inches was expected in the northern portion of the state. However, the storm's track remained uncertain early Monday, and forecasters warned that even a slight change in its path could significantly alter the amount of snow that hit the region.

"Even with some new information we're getting right now, we're still not completely sure what will happen with this [storm system]," Patrick O'Hara, a meteorologist with the National Weather Service in Mount Holly, said late Sunday night.

Monday's storm was expected to be an all-snow event, a change from the mixed precipitation that coated the state Sunday morning.

Snowfall totals from that storm varied widely, from trace amounts in Atlantic City to a high of 4 inches reported in Ewing Township, Mercer County. However, the combination of snow, freezing rain and sleet left many roadways slick and icy, and three people died early Sunday in two separate single-car accidents.

Meanwhile, numerous accidents — mostly spinouts with minor injuries — were reported along the New Jersey Turnpike and Garden State Parkway, as well as secondary and local roads around the state. State police spokesman Steve Jones said troopers responded to 586 accidents by early Sunday night, including 246 on the Turnpike and Parkway, and 25 on the Atlantic City Expressway.
