A nor'easter low pressure system developing along the coast of the Carolinas is expected to move toward the hard-hit Hurricane Sandy areas bringing heavy rain and strong winds Wednesday into Thursday to New York, New Jersey and Pennsylvania, the National Weather Service reports.
The system could produce strong northeast winds and moderate to heavy rain, with Wednesday night seeing some snow in the higher elevations of the Lehigh Valley and 1-4 inches over the southern Poconos.
The approaching system will not arrive until after Election Day, which in the Lehigh Valley should be a sunny day with a high temperatures of about 45 degrees.
With the storm system still two days away, weather models show rainfall amounts could range from under an inch to between 1-11/2 inches. The highest amounts of rain would fall east of the Interstate 95 corridor, and the strongest winds would likely be along the northern New Jersey coastline.
Separate high pressure systems before and after the nor'easter will impact temperatures, with the first keeping temperatures below normal and the latter raising temperatures to near normal. The Lehigh Valley forecast shows temperatures climbing into the upper 50s Saturday and Sunday.
Recovery efforts that began after Hurricane Sandy came ashore in New Jersey Monday night as a post-tropical cyclone or Superstorm Sandy could be hampered or delayed until the nor'easter passes. The storm could cause moderate tidal flooding along the coast, Raritan Bay and lower Delaware Bay, but there are no major inland flooding concerns.
However, the National Weather Service says the storm could further damage trees weakened during Sandy and hamper work to restore power.
The low pressure system is referred to a nor'easter or northeaster because the storm moves from the south to the northeast and the winds come from the northeast.
