Flooding, snow a threat for New Jersey roads Tuesday

The first round of snow passed through New Jersey early Tuesday whitening the ground and cars, but largely left the roads alone.

Still, it's having an effect on traffic:

The Garden State Parkway had a reduced speed of 45 mph in effect between Exist 30 (Route 30) in Somers Point and Exit 124 in Sayreville just before the Driscoll Bridge. An accident on Route 1 southbound in West Windsor early Tuesday morning caused a multi-mile delay as a fuel spill was cleaned up but it was moved to the shoulder by police. It's not known if that incident was weather related.

A higher than normal high tide led  to the closure of lanes along some  immediate coastal routes on Tuesday morning.. Route 36 in Sea Bright remained closed between Center Street and the Highlands Bridge in both directions while Route 35 had lanes blocked for high water in Brielle and Belmar. Long Beach Boulevard on Long Beach Island was also flooding. Gateway National Park in Sandy Hook is closed due to flooding on Tuesday.

Route 40 in Atlantic City including ramps from the Atlantic City Expressway were also been closed around high tide.

"Surge models show Tuesday morning’s tides will be the highest of the week," said meteorologist Dan Zarrow. North Wildwood Mayor Patrick Romanello said he expects the tide will be higher than Monday. "The only difference is that it is a much calmer day with  lower winds and the ocean isn't as whipped up."

The National Weather Service has a winter weather advisory in effect for most oft the state until Wednesday morning, while a coastal flood advisory is posted until late Tuesday afternoon.

Tuesday afternoon's commute will be more affected by snow than the morning.

"Occasional periods of snow mixed with rain are expected throughout the daytime hours on Tuesday. The heaviest precipitation of the storm should hold off until later, moving into the southern half of the state (below I-195) between about 2 and 8 p.m. Tuesday," Zarrow said.
