A nor'easter will bring another round of coastal flooding to the mid-Atlantic and southern New England Wednesday into Thursday. This will affect the areas that were hardest hit by Hurricane Sandy last week.
Along with heavy rain, strong winds and interior snow, this nor'easter will bring a water rise of 2 to 4 feet above tide level to some areas.
A water rise of this magnitude normally wouldn't be as significant an issue; however, Hurricane Sandy damaged or destroyed a lot of the dunes that were in place to protect beach communities from this scenario.
With limited or damaged dunes in place, the water will have free reign to flow into coastal communities, especially along a portion of the New Jersey coastline.
This nor'easter's wind pattern will be different than what occurred with Sandy. The primary wind direction with Sandy was out of the southeast, but this storm will have more of a northerly wind for the mid-Atlantic and northeasterly wind for the New England beaches. In many cases this wind direction will work to push almost as much water away from the coast than that which trying to coming in from farther out to sea.
A north to northeasterly wind means that the most significant coastal flooding will occur along the northern coast of Delaware, northern New Jersey, the western end of the north shore of Long Island, N.Y. and eastern Massachusetts.
At the present time, AccuWeather.com meteorologists are expecting a 2- to locally 3-foot water rise on top of the normal tide level from about Ocean City, Md., through Atlantic City, Belmar and Sandy Hook, N.J.
A water rise of 1 to 2 feet above normal tide levels are likely from Staten Island through Long Beach, Fire Island and Hampton Beach, N.Y.
Additional areas of higher water rises will occur across the western end of Long Island Sound where a northeast wind will cause water to pile up along the north shore of Long Island. A water rise of 3 to 4 feet above normal tide level is possible in this region.
Water levels of about 2- to locally 3-feet above normal are forecast along the Connecticut and Rhode Island coasts.
The worst of the coastal flooding and strongest winds are expected during two phases on Wednesday. The two times that are of utmost concern across the region are during high tide Wednesday afternoon and a second high tide late Wednesday night/early Thursday morning.
Below is a table of Wednesday afternoon high tide times and expected water levels. The water levels factor in both the tides and storm surge.

Residents still cleaning up from Sandy are urged to take precautions by securing or removing debris that was left by Sandy as objects can be tossed around easily by the high winds.
Coastal residents are urged to take precaution against another round of rising water as there isn't much protection in place to hold the water back.
Additional power outages and damage to trees will be likely due to the already soft ground in place across the region.
